(a) Lateral venogram of patient who underwent modified radical neck dissection, showing flow straight down ipsilateral internal jugular vein. Since Crile's landmark publication in 1906, the radical neck dissection (RND) has remained the criterion standard for excision of cervical nodal metastases resulting from head and neck cancer. Bladder Neck Transection. Lesser resections are involved in modified radical neck dissection and selective neck dissection. During this period, the neck dissection literature lacked any standardization in the nomenclature describing each surgical procedure, resulting in an initiative by the Committee for Head and Neck Surgery and Oncology of the American Academy of Otolaryngology/Head and Neck Surgery to standardize the diverse nomenclature. Modified Radical Masectomy Warujpong Boonkum Vestibular schwanoma 03342729593 NASOPHARYNGEAL CARCINOMA Mamoon Ameen Tumors of the Lung and Surgery of Mediastinum Muhammad Eimaduddin Occult primary mangmnt Md Roohia NECK DISSECTION- A COMPREHENSIVE STUDY Priyanko Chakraborty carcinoma breast RADIOTHERAPY TECHNIQUES Nabeel Yahiya The modified radical neck dissection, which advocated for the preservation of at least one of the critical non-lymphatic structures (CNXI, IJV, or SCM) was proposed by Drs. Injury to the SAN results in dysfunction of the trapezius muscle. Medscape. A rational classification of neck dissections. Cells from cancers in the mouth or throat can travel in the lymph fluid and get trapped in your lymph nodes. Head and neck cancer is cancer of the oral cavity, salivary glands, paranasal sinuses and nasal cavity, pharynx, larynx, or lymph nodes in the upper part of the neck. This nerve is not really in the area of dissection, but it can be compressed by retractors during the procedure. A 71-year-old patient with tongue cancer underwent radical excision. An en bloc approach should be pursued, and nodal metastases encapsulated by reactive connective tissue must be resected atraumatically. Modified neck dissection. A selective neck dissection refers to a cervical lymphadenectomy in which there is the preservation of one or more of the lymph node groups that are . Epub 2014 Apr 1. de Campora E, Radici M, Camaioni A, Pianelli C. Eur Arch Otorhinolaryngol. The submental (IA) and submandibular contents (IB) have been dissected away from the underlying soft tissues (arrow). The different types of neck dissection are classified based on the site (zones I-V) from where nodes are being removed and whether the following three important surrounding structures are removed: Apart from modified radical dissection, the other types include: The goal of neck dissection is to remove all cancer while preserving as much healthy tissue as possible. Modified radical neck dissection type 3 is indicated in metastatic differentiated thyroid carcinoma 10. Crile G. Excision of cancer of the head and neck with special reference to the plan of dissection based on one hundred and thirty-two operations. Am J Surg. Terminology, technique, and indications The terminology relating to the various modifications of radical neck dissection is loose and confusing. Treatment selection bias probably also affected the results of these retrospective studies because MRND may have been used to treat less-advanced nodal metastatic disease. Sternocleidomastoid muscle (SCM) resection results in loss of normal contour in the anterior neck with resultant cosmetic deformity. These cancers account for 3% to 5% of cancers in the U.S. Tobacco and alcohol use are important risk factors. Epub 2014 Sep 17. This study was planned to determine whether Selective Neck Dissection (SND) is oncological safe procedure even in patients with lymph node metastases. https://profreg.medscape.com/px/getpracticeprofile.do?method=getProfessionalProfile&urlCache=aHR0cHM6Ly9lbWVkaWNpbmUubWVkc2NhcGUuY29tL2FydGljbGUvODU0Mjk2LW92ZXJ2aWV3. Variations on neck dissections exist, depending on the extent of the cancer. These 2 studies offered valuable insight about patterns of nodal metastases and provided a rationale for the modified neck dissection and the selective neck dissection. . No formalized indications have been created for modified radical neck dissection (MRND), and indications vary widely from one clinician to another. Patients should be counseled that loss of cutaneous sensation occurs in the distribution of the cervical plexus, including the skin of the neck and the periauricular region. As it is classically described, the dissection is carried across the inferior portion of the parotid tail including it in the specimen. These give sensation to neck, anterior shoulder, lower jaw area and the area near the lower part of the ear. Removal of sternocleidomastoid (SCM) muscle with secondary asymmetry, Removal of spinal accessory nerve with secondary shoulder weakness and pain (see Shoulder Rehab), Possible injury to hypoglossal nerve with secondary tongue weakness affecting speech and swallow, Possible injury to vagus nerve with secondary weakness in voice and swallow, Possible injury to facial nerve with secondary weakness of lower lip and/or face, Possible injury to sympathetic trunk with secondary Horner's syndrome, Possible injury to thoracic duct with secondary chyle leak, Risk of significant facial or cerebral edema (primarily if both jugular veins are removed or injured).

In: Lore JM, ed. If the SCM is being resected, transection is performed below the mastoid tip and above the clavicle as in a RND. Modified radical neck dissection (MND) is a complicated operation. During the neck dissection, the sternocleidomastoid muscle was removed and a major nerve (forget the name) cut and repaired. This nerve runs deep in the neck. At this time, intraoperative assessment is necessary to determine the proximity and/or fixation of lymph node metastases to the IJV, SAN, and SCM. Neck pain is any degree of discomfort in the front or back of the neck between the head and the shoulders. Shoulder pain and function after neck dissection with or without preservation of the spinal accessory nerve. MND is very effective treatment for regional node disease. A modified neck dissection removes less tissue than a radical procedure, and a selective neck dissection removes the least amount of tissue of all these types of surgeries. The approach is more useful when the surgeon chooses to resect the SCM from the onset of surgery. Antibacterial ointment is then applied to the incision line. Use cautery to separate the SCM attachments posteriorly from the skin and mastoid tip. Carver College of Medicine Further, only specific groups of lymph nodes rather than all the lymph nodes on the side of the neck are dissected. on exactly the same lines as the Halstead operation for cancer of the breast. Injury to this nerve is very rare. Neck dissection is surgery to remove the lymph nodes in your neck. Modified radical neck dissection. The specimen is dissected free of the internal jugular vein, and brought over or under it to join the medial portion of the dissection. Head Neck. Please confirm that you would like to log out of Medscape. I'm a thankful 5 year survivor of thyroid cancer (papillary carcinoma). The IJV is once again evaluated. The term "modified RND" refers to preservation of nonlymphatic structures, whereas the term "selective neck dissection" refers to preservation of levels of lymphatics. "Although the laryngectomy with neck dissection code describes a radical dissection, not a modified radical, it can be frowned upon to bill the modified radical," says Barbara Cobuzzi, MBA, CPC, CPC-H, an otolaryngology coding and reimbursement specialist and president of Cash Flow Solutions, a physician billing firm in Brick, N.J. Laryngoscope. 1990 Nov-Dec. 12(6):476-82. (Their findings are reviewed in the section Supporting Evidence.). If the SAN can be preserved, dissection is then continued from its proximity to the IJV posterocaudally to the trapezius muscle, dividing the SCM (see the image below). Type II: The spinal accessory nerve and the internal jugular vein are preserved. You may have a neck dissection if there is a high risk of the cancer spreading to the lymph nodes in your neck. Raleigh, NC 27607, PAUL PARK MD Terms of Use. Upfront chemoradiotherapy can also be a valid therapy technique however, as with N2 illness, patients requiring salvage surgery endure . Patients who underwent surgery and postoperative radiotherapy, 100% of whom had jugulodigastric nodal involvement, demonstrated a 0% recurrence rate (see Table 3). Use This Code : You Be The Coder. Care is taken during flap elevation to remain superficial, preserving the greater auricular nerve and the SAN (see the image below). Chapter 113: Neck Dissection. 3rd ed. Cf Radical neck dissection. John Werning, MD, DMD, FACS Associate Professor, Department of Otolaryngology-Head and Neck Surgery, University of Florida College of Medicine Suarez later realized that cervical lymphatics are contained within fascial spaces, consisting of the fascia covering the submandibular glands, carotid sheath, SCM and deep cervical muscles and nerves, and he incorporated this fact ino his neck disections. The terminology relating to the various modifications of radical neck dissection is loose and confusing. Careers. Resection may also contribute to fibrosis and limitation of range of cervical motion. Bethesda, MD 20894, Web Policies This classification has become widely accepted and has also been endorsed by the American Head and Neck Society. Neck dissection is usually performed to remove cancer that has spread to lymph nodes in the neck. Epub 2006 Aug 4. 1994;251(6):335-41. doi: 10.1007/BF00171540. Patient. World J Surg. Selective neck 3. Background & Aims: To describe unilateral and bilateral modified radical neck dissections with access to the thyroid gland and all neck lymph node levels through a single supraclavicular transverse incision. Small branches may be controlled with bipolar electrocautery. Neck pain (cervical pain) may be caused by any number of disorders and diseases. 1990 Feb. 104(2):154-6. Medina JE. The most important permanent risk of surgery involves nerve injury. Offer. There are several types of neck dissections. With any unexplained or persisting neck pain or dizziness, consult with a health care professional, who can determine whether the symptoms are harmless and temporary or serious and threatening. 1996-2022 MedicineNet, Inc. All rights reserved. An image depicting a neck dissection incision can be. 47:1780-1786. MedicineNet does not provide medical advice, diagnosis or treatment. 1989 Mar. Postoperative radiotherapy reduced the recurrence rate to 7% in 43 additional dissected neck sides with extracapsular spread (see Table 2). Patients who underwent a supraomohyoid neck dissection had the least dysfunction. Sacrifice or preservation of the new lymphatic structures usually depends on the size and extent of lymph node metastases at level II, the upper jugular lymph nodes. Injury to this nerve is quite rare as it is easily seen and few lymph nodes are near it. However, a plane of dissection was easily developed between the SAN and the nodal metastases. Tying rootlets with 2-0 silk (or using hemoclips) may theoretically decrease the risk of neuroma. A modified radical neck dissection (38724) is a little more difficult, but also involves removal of all the lymph nodes from levels 1 through 5. The preserved nonlymphatic structures should be specifically mentioned (eg, modified radical neck dissection with preservation of the IJV and SCM). Crile G. Excision of cancer of the head and neck. 110(4):620-6. Functional Neck Dissection* (Open Table in a new window). As the last fibers of the SCM are divided, the internal jugular vein and omohyoid muscle are fully exposed. Modified radical neck dissection (MRND). An extensive body of literature documents morbidity following RND. Utility or Lahey incision made in the skin creases of the neck beginning in the low neck and extending to the mastoid tip; occasionally a posterior limb is added, Schobinger incision, which has a high horizontal limb (hyoid to mastoid tip) and long curving descending limb; this may be most useful in treating oral primary lesions. Postoperative complications following modified radical neck dissection (MRND) match those experienced with radical neck dissection (RND) and include hematoma, infection, skin flap necrosis, chyle fistula, marginal mandibular nerve injury, and carotid artery rupture. 1994 Jul. 66(1):109-13. J Craniomaxillofac Surg. In the past, patients with neck cancer persistence or recurrence after irradiation or chemo-radiation were generally treated with a comprehensive neck dissection. The posterior belly of the digastric muscle is retracted superiorly and the internal jugular vein is ligated at the base of skull. It is not always necessary to resect the tail of the parotid gland. Modified radical neck dissections remove levels I-V (similar to a radical neck dissection). [14] Overall, he encountered an 8.1% recurrence rate in the neck 5 years following surgery. John Werning, MD, DMD, FACS is a member of the following medical societies: American Academy of Facial Plastic and Reconstructive Surgery, American Academy of Otolaryngology-Head and Neck Surgery, American College of Surgeons, American Head and Neck SocietyDisclosure: Nothing to disclose. Radical neck dissection Refers to the removal of all lymph node groups extending from the inferior border of the mandible superiorly to the clavicle inferiorly, from the lateral border of the sternohyoid muscle, hyoid bone, and contralateral anterior belly of the digastric muscle medially, to the anterior border of the trapezius muscle laterally. The neck recurrence rate for elective FND was 2.3% versus 30.4% for therapeutic FND. The skin with surgical clips, 4-0 or 5-0 nylon. The suprahyoid muscles are the digastrics, stylohyoid, mylohyoid, and geniohyoid. 2011 Feb. 33(2):274-80. You should rather give importance to the surgeons experience and your rapport and comfort level with them. Indications for MRND-I is in bulky nodal disease with extracapsular spread involving the SCM and IJ, where the accessory nerve is free of . However, 26% of the 27 neck dissections that had multiple involved lymph nodes with extracapsular spread developed recurrence. Dissect internal jugular vein identifying the vagus nerve and carotid. Modified radical neck dissection preserves the structures that are usually sacrificed in the standard radical surgery, such as the spinal accessory nerve, the internal jugular vein, or sternocleidomastoid muscle. Postoperatively, compression of the IJV should be minimized by avoiding tight dressings and tracheostomy tube ties. Int J Clin Oncol. Alternatively, preserve the internal jugular vein. [QxMD MEDLINE Link]. Balm AJ, Brown DH, De Vries WA, et al. 1978 Oct. 136(4):516-9. A study of 967 cases from 1970 to 1980. 200 Hawkins Drive Most patients take narcotic pain medication for 1-2 weeks. RND includes resection of sternocleidomastoid muscle (SCM) and accessory nerve (XIn) and internal jugular vein (IJV). 2005 Oct. 131(10):874-8. See additional information. Previous extensive blunt dissection along the posterior aspect of the IJV prevents elevation of the neck dissection over the IJV. A final risk of surgery involves the Thoracic duct. This is a large thin-walled lymphatic vessel that is present at the base of the neck and empties lymphatic fluid from the body into the blood stream at the jugular vein on the left side of the neck. [15] They were unable to demonstrate a statistical difference in the neck recurrence rate overall or in patients with N2 or N3 disease. Blindness: a potential complication of bilateral neck dissection. A muscle on the side of your neck called the sternocleidomastoid muscle, Sometimes, a combination of either of these structures may be removed. The surgeon attempts to preserve the important neck structures as far as possible in modified neck dissection. 1992 Apr. [QxMD MEDLINE Link]. MND preserves SCM and/or XIn and/or IJV. For patients who are clinically staged N0 or N1, a selective neck dissection or MRND would be appropriate. The contents of levels II, III, and IV have been elevated after division of the omohyoid muscle. A further Level VII to denote lymph node groups in the superior mediastinum is no longer used. Head Neck. 2800 Blue Ridge Road, Suite 300 Modified radical neck dissection preserves the structures that are usually sacrificed in the standard radical surgery, such as the spinal accessory nerve, the internal jugular vein, or sternocleidomastoid muscle. In general, however, loss of the SCM results in the least morbidity of the 3 nonlymphatic structures sacrificed during RND. No prospective studies compare modified radical neck dissection (MRND) with radical neck dissection (RND), and few studies exist that have compared the outcomes following RND with outcomes following MRND. A posterior to anterior dissection is then performed beginning at the anterior border of the trapezius muscle. Intracranial pressure changes during bilateral radical neck dissections. The dissected contents of sublevels IA and IB are then elevated over the digastric muscle in continuity with the nondissected portion of the neck (see the images below). See additional information. The submandibular triangle in radical neck dissection. A closer look at the individual findings of Byers and Shah, however, can provide clinicians with applicable information that supports the use of the MRND in properly selected patients. Of the patients who underwent surgery alone, 73% had pathologic jugulodigastric node involvement with an 8% recurrence rate in the dissected neck. Rarely, this plexus may be important if cancer penetrates deeply (inferiorly) down the neck through the thoracic inlet into the upper chest. CPT code 60252 is reported when a limited neck dissection is done, while CPT code 60254 is reported if a radical neck dissection is included in the procedure. Medina JE, Weisman RA. On the affected side, patient experience difficulty raising the eyelid, diminished sweating on that side of the face and a constricted pupil. Head and neck cancers include cancers of the throat, lips, nose, mouth, larynx, and salivary glands. Of 343 elective neck dissections, 113 had pathologically documented nodal metastases. [QxMD MEDLINE Link]. We now refer to this as a "modified neck dissection." 1985 Oct. 150(4):414-21. There are different types of modified radical neck dissection. A radical neck dissection would be done if the tumor spread to the neck is quite extensive. A radical neck dissection removes all the lymph nodes in the neck on one side, as well as the sternocleidomastoid muscle (SCM), the internal jugular vein (IJV), and cranial nerve XI or the spinal accessory nerve. Therefore, an MRND with preservation of the SAN was performed. Patients with persistent pain and dysfunction after 1 year of conservative treatment may be candidates for surgical reconstruction with the Eden-Lange procedure, in which the insertions of the levator scapulae, rhomboideus minor, and rhomboideus major are transferred. However, these patients tended to demonstrate improvement in their EMG results over time. Cpt Code Modified Radical Neck Dissection . Many patients with N3 disease (nodal metastases > 6 cm) require RND, but MRND can be considered when dissection is feasible. Lymph nodes are small bean shaped glands scattered throughout the body that filter and process lymph fluid from other organs. FOIA Modified radical neck dissection The removal of the cervical lymph nodes is the neck dissection 'neck dissection,' and various types of neck dissections 3. 1994 Dec;22(6):323-9. Treatment at home may incorporate resting, icing, and elevating the injury. You are being redirected to Dissection proceeds superiorly going from posterior to anterior superficial to the deep cervical fascia. Before The nerves at risk with MND fall into two broad categories. Shah JP, Candela FC, Poddar AK. Medina JE. Modified radical neck dissection (MRND). Arch Otolaryngol. The author prefers to use an apron flap design that extends from the mastoid tip to the mandibular symphysis (see the first image below). Robbins KT. Although the term MRND strictly implies a comprehensive dissection of levels I-V, in the context of thyroid cancer, dissection . Terrell JE, Welsh DE, Bradford CR, et al. When the jugulodigastric nodes in the upper anterolateral neck were pathologically involved and the nerve was preserved, the recurrence rate decreased from 17% to 4.7% with the use of postoperative radiotherapy. PMC This surgical incision location is ideal to minimize scarring, while also enabling the surgeon to safely remove any cancerous lymph nodes. Subplatysmal plane leaving cervical plexus nerves and external jugular veins down, If tumor is close to the platysma, elevate the skin above the platysma in that region (elevate subcutaneously). 1951 May. The sternocleidomastoid muscle has been bisected to preserve the spinal accessory nerve as it courses towards the skull base. It was the standard of care for the next 70 years. (Above, left) The defect involved the tongue, floor of the mouth, mandible, and posterior . 2000 Apr. Radical neck dissection removes nearly all lymph nodes on one side of the neck as well as the internal jugular vein, sternocleidomastoid muscle and . Patients present with an asymmetric neckline, a drooping shoulder, winging of the scapula, and weakness of forward elevation. May be a useful preoperative evaluation if the risk of entering the carotid is high, even if resection of the carotid artery is not planned. This problem occurs in about 3% of patients and is an issue only with left MND. Further, only specific groups of lymph nodes rather than all the lymphnodes on the side of the neck are dissected. Unable to load your collection due to an error, Unable to load your delegates due to an error. Most recently, Terrell and colleagues found no significant difference in shoulder or neck pain between patients who underwent MRND and those who underwent RND, but patients treated by RND used pain medications more frequently. However, patients receiving radiotherapy combined with surgery were not evaluated separately from patients who underwent surgery, and patients who underwent delayed neck dissections were also grouped with patients treated with immediate neck dissections. [QxMD MEDLINE Link]. The Latin-derived term cervical means "of the neck." A modified radical neck dissection, which is the most comprehensive form of functional neck dissection, entails the resection of the nodal groups I through V, and is still considered the standard of care for management of the cN + neck. During surgery, trauma to the IJV should be minimized by atraumatic manipulation and avoiding IJV desiccation. Shoulder immobility or spinal accessory nerve palsy is reported as the most common complication occurring in 10% of patients after selective or modified radical neck dissection [ 9 ], but with preservation of . Radical neck dissection - discharge; Modified radical neck dissection - discharge; Selective neck dissection - discharge. Concerns regarding sternocleidomastoid muscle (SCM) resection focus mainly on the cosmetic deformity that results from loss of muscle mass and the subsequent change in normal contours of the anterior neck. Lymph nodes may be intimate to it. [5] Of these patients, 42 experienced shoulder discomfort, and 60 demonstrated shoulder stiffness and decreased range of motion. Patients who undergo MRND with preservation of the spinal accessory nerve (SAN) may develop shoulder pain and dysfunction. Spinal accessory nerve injury. Injury to this nerve will compromise shoulder function especially raising the shoulder. government site. EndocrineSurgeryNC.com has been created by Dr. Faust and reflects his professional opinions. Level V Metastasis in RND Patients*. This description is combined with intraoperative photographs and . Elevation of the level I contents out of the submental and submandibular triangles, exposing the digastric and mylohyoid muscles. 2. The purpose was to effectvely remove all of the lymph nodes present in the neck and their interconnecting lymphatics. 1984 Oct. 148(4):478-82. Sobol et al performed electromyography 16 weeks following surgery. There are different types of modified radical neck dissection. Modified radical neck dissection (MRND). modied radical neck dissection (MRND) for papillary thyroid carcinoma with clinically positive lymph nodes in the lateral compartments. [QxMD MEDLINE Link]. Medina JE. Identify the angle of the jaw, mastoid tip, midline of the neck, anterior and posterior borders of the SCM muscle and the clavicle. The immune cells in the lymph nodes help the body fight infection. The standardization of terminology is important to communicate to other practitioners which levels were dissected and which structures were resected for postoperative management. Mitzner R. Neck Dissection Classification. Shah JP. This problem has been reported after extensive dissection around the carotid artery as well. Further advancements have demonstrated that depending on the situation, not all levels must be explored, thus developing the concept of the "selective neck dissection.". In 1980, a method for modified radical neck dissection was reported and then accepted as a substitute for classic neck dissection. Accessibility Alternatively, preserve the internal jugular vein;. Dissection in this area could result in a Horners syndrome. Increasing awareness of the morbidity associated with radical neck dissection (RND) led head and neck surgeons to explore modifications of the classic procedure. The plane of dissection should be just superficial to the adventia of the vein. Functional neck dissection: an evaluation and review of 843 cases. It is uncommon to require sacrifice of XI. I've gotten use to the limited mobility in my neck, soreness in my left arm and dry mouth. [QxMD MEDLINE Link]. The internal jugular vein is encountered and XI nerve is either divided a second time (less commonly) or retracted (more commonly) if one intends to preserve it. Other researchers have similarly demonstrated the disability resulting from neck dissection. 2006 Dec;33(4):365-74. doi: 10.1016/j.anl.2006.06.001. Selective Neck Dissection - Only some of the lymph nodes and tissues are removed. . The site is secure. A technique of modified neck dissection, which excludes dissection of the posterior triangle and spares the sternocleidomastoid muscle and spinal accessory nerve, has been described. Dissection continues superiorly deep to the digastric up to the lateral process of C2. 1984 Jul. Ipsilateral radical neck dissection or selective neck dissection (levels 2 5) is indicated for the N2/3 neck. This nerve is high and very shallow in the neck. Khafif et al compared the outcomes of patients who underwent RND with the outcomes of those who underwent MRND in 1990. It is modified in the structures it preserves. Byers RM. health & living health center/related resources /what is removed in a modified radical neck dissect article. Identification of the spinal accessory nerve (SAN; arrow) posterior to the sternocleidomastoid muscle (SCM) as it courses through the posterior triangle to the trapezius muscle. 1988 Sep;167(3):259-69. Causes of neck pain and dizziness vary, and treatment depends on the cause. This large nerve runs the length of the neck along the major blood vessels. It controls a large muscle of the shoulder called the trapezius. Neck dissection for cutaneous malignant melanoma. Illustrated by: Timothy McCulloch, MD, Copyright The University of Iowa. The neck supports the weight of the head and is highly flexible, allowing the head to turn and flex in different directions. Completed modified radical neck dissection (MRND). Ann Surg Oncol. Bookshelf In the healing setting, postoperative chemoradiotherapy is normally necessary for a chance at native control. Surgeons don't routinely do a neck dissection on everyone because it can have long-term side effects. Furthermore, if evidence of extranodal fixation to the surrounding soft tissues of the neck (ie, deep cervical musculature) is found, performance of an RND (or extended RND) must be considered because of the advanced stage of regional metastatic disease present. The posterior triangle contents are elevated in an en bloc fashion off the fascia of the deep cervical musculature, preserving the phrenic nerve and the brachial plexus, located deep to this fascia. Strong EW. The nerve branch can be identified beneath the prevertebral fascia between the middle and posterior scalene muscles, and confirmed by stimulation. The marginal mandibular nerve can be preserved by elevating the submandibular gland fascia as part of the flap or by elevating the flap deep to the common facial vein after dividing it. Identification of the spinal accessory nerve anterior to the sternocleidomastoid muscle in the contralateral neck of the same patient as it courses lateral to the internal jugular vein. Modified radical neck dissection To describe the lymph nodes of the neck for neck dissection, the neck is divided into 6 areas called Levels. Additional concerns arise when neck dissection is combined with pharyngeal procedures and/or when bilateral neck procedures are performed: Nerve stimulator control unit and instrument, Place towels outlining the chin, neck, and upper chest, 10 mm fully-perforated Jackson Pratt drains, Tube position: Corner of mouth contralateral to procedure, 150 cc (transfusion is very rare unless the neck dissection is accompanied by other concurrent surgery, such as composite resection or free flap). [10, 11, 12] They demonstrated that nodal metastatic disease predictably occurs in certain regions of the neck based on the site of the primary tumor. In the absence of a prospective randomized comparison of these 2 surgical procedures, the results discussed above support the oncologic safety of the MRND in a number of situations in which the RND was previously routinely performed. Head Neck. This nerve is difficult to identify and while injury is uncommon, it is an important source of problems for affected patients. He described the removal of all five lymph node levels in the neck while preserving the spinal accessory nerve, sternocleidomastoid muscle, and internal jugular vein to limit any functional disability . If there is extensive disease around the carotid artery, preoperative evaluation of carotid and cerebral blood flow may be valuable including four-vessel cerebral angiography and carotid balloon test occlusion if consideration for carotid resection is entertained. Consequently, the indications for MRND and selective neck dissection in these patients also remains poorly defined. Also, see eMedicineHealth's patient education article Cancer of the Mouth and Throat. Injury is very rare. Second, to let others who may find themselves with the same diagnosis know they can reach out. Would you like email updates of new search results? Ann Otol Rhinol Laryngol. Increased intracranial pressure may result, and reports of blindness, laryngeal edema, stroke, and death exist within the medical literature. The sternocleidomastoid muscle has been transected inferiorly and the external jugular vein has been ligated. I, therefore, extend the incision laterally (parallel to the clavicle) to the anterior border of the trapezius muscle. 1977 Dec;103(12):705-6. doi: 10.1001/archotol.1977.00780290041003. Shah retrospectively reviewed 1081 patients who underwent 1119 RND procedures with an average harvest of 39 lymph nodes. Full recovery from the surgery is about a month to 6 weeks. In addition, these studies differed in their indications for neck dissection, use of preoperative or postoperative radiotherapy, and follow-up interval. Cotter CS, Stringer SP, Landau S, et al. Modified radical neck dissection (MRND). Clipboard, Search History, and several other advanced features are temporarily unavailable. July 2005 edited March 2014 in Head and Neck Cancer #1. Hence, comparing the outcomes of RND and MRND in these series is of limited value. Otolaryngol Head Neck Surg. Identify the nerve as it exits posteriorly to the SCM, 1 cm superior to Erbs point, or infero-laterally as it courses superficially to the lower one-third of the trapezius muscle. They have to carefully consider who will benefit from it.

Raleigh, NC 27607, TELEPHONE: (919) 784-7874 A simple system of nomenclature has been suggested which allows specification of the node levels dissected and the structures preserved. The bladder neck transection can be a problematic for novice surgeons, due to the junction's innate natural anatomic variability and the absence of obvious visual landmarks [21, 25].The assistant plays a critical role identifying the junction between the bladder neck and the prostate [].Switching the camera to the 30-degree down scope, first identify the . Radical neck dissection (RND) refers to the removal of all ipsilateral cervical lymph node groups extending from the inferior border of the mandible superiorly to the clavicle inferiorly and from the lateral border of the sternohyoid muscle, hyoid bone, and contralateral anterior belly of the digastric muscle anteriorly to the anterior border of the trapezius muscle posteriorly. The contents of the submental triangle (sublevel IA) are then elevated from the inferior border of the mandible and the opposite digastric muscle off of the mylohyoid muscle, leaving the overlying muscle fascia intact.
