Skin flaps are raised in the subplatysmal plane from the mandible down to the clavicle. [18]The marginal mandibular branch is also commonly injured, with rates ranging from 5% to 12%.[18][19]. The majority of the time (~85%), CN XI runs superficial to the IJV, but it may also run deep (~14%) or through (<1%) the IJV as well[10]. The spinal accessory nerve and the transverse cervical vessels are divided as they cross the anterior the border of the trapezius muscle. When the daily output of chyle exceeds 600 mL in a day or 200 to 300 mL per day for 3 days, especially when the chyle fistula becomes apparent immediately after surgery, conservative closed wound management is unlikely to succeed; these are indications for surgical exploration. - Definition, Function & Examples, Ectropion: Definition, Symptoms & Treatment, Etiology of Disease: Definition & Example, Pediculosis: Definition, Symptoms & Treatment, Radical Neck Dissection: Definition, Complications & Side Effects, What Is a Morbidity Rate?

The most important aspects of success involve interprofessional care of the patient. In a type III MRND CN XI, the IJV and the SCM are all spared. The muscle, nerve, salivary gland, and major blood vessel in this area are all removed. Modifications to the radical neck dissection include the following: Type I: The spinal accessory nerve is preserved. Identifying Marginal mandibular nerve: Careful identification of the marginal mandibular branch of the facial nerve is crucial. [13], Other relative contraindications include uncompensated coagulopathy, poor overall health with a high risk of anesthetic complications, and poor neurocognitive state. An official website of the United States government. The wound is then closed in layers. Next, the tendons of the digastric and stylohyoid muscles are divided while protecting the hypoglossal nerve (CN XII), allowing for access to the superior aspect of the IJV and the submandibular region contents. This nerve lies just anterior to the submandibular fascia and superficial to the posterior facial vein. Anterolateral neck dissection: En bloc nodes from I, II and III The posterior flap is then raised in the subplatysmal plane by applying traction to the flap with skin hooks and counter-traction of the deeper soft tissues. Carotid artery rupture. Kerawala CJ, Heliotos M. Prevention of complications in neck dissection. A radical neck dissection would be done if the tumor spread to the neck is quite extensive. Key structures and relationships: The lingual nerve, hypoglossal nerve, submandibular duct, and facial artery and vein are all found in level I. Interprofessional cooperation will assist in making sure patients obtain the best outcomes. Care is taken to avoid injury to the vagus nerve during the dissection. The submandibular gland andassociated lymph nodes are then reflected superiorly and raised off of the mylohyoid. The omohyoid muscle, which lies just superficial to the IJV,is also divided. Boundary: Level IV is bounded by the posterior border of the SCM laterally, the lateral border of the sternohyoid medially, the inferior border of the cricoid superiorly, and the clavicle inferiorly. Bocca E, Pignataro O, Oldini C, Cappa C. Functional neck dissection: an evaluation and review of 843 cases. - Definition, Causes, Symptoms & Treatment, What Is Chemotherapy? - Causes, Symptoms & Treatment, What Is Pyrexia?

In type II, MRND CN XI and the IJV are spared. The loss of trapezius function decreases the patients ability to abduct the shoulder above 90 degrees at the shoulder. Federal government websites often end in .gov or .mil. Next, the marginal mandibular nerve is identified and protectedby elevating the fascia overlying the submandibular gland. Once deep to the cervical rootles, care must be taken to avoid injury to the phrenic nerve and brachial plexus. Level II (upper jugular lymph nodes - level IIa begins at the posterior border of the submandibular gland and extends to the accessory nerve, level IIb is the node-bearing tissue bordered anteriorly by the accessory nerve and posteriorly by the trapezius and suboccipital muscles) borders are: 3. 6. Radical neck dissection dissection upon site, and may be as high as 50% (Fig. Cervical lymphadenectomy is most frequently classified according to the associated anatomic domain sampled, with central neck and modified radical neck dissections being the most commonly described nodal harvesting procedures for thyroid cancer. Level: I (submental and submandibular nodes). A radical neck dissection will include between 10-30 lymph nodes (unless affected by chemotherapy or radiotherapy) but 50-100 nodes have been found in some specimens. Subramanian S, Chiesa F, Lyubaev V, Aidarbekova A, Brzhezovskiy V. The evolution of surgery in the management of neck metastases. ), FRCS(Eng.),FRCS(Glas.

The SCM and IJ are then reflected superiorly, allowing access to the supraclavicular lymph nodes and the floor of the neck (composed of the splenius capitus, levator scapulae, and scalene muscles). Access free multiple choice questions on this topic. Refers to the removal of all lymph nodes by radical neck dissection with preservation of one or more of the non-lymphatic structures: i.e., the spinal accessory nerve, internal jugular vein and the sternocleidomastoid muscle. de Vries EJ, Sekhar LN, Horton JA, Eibling DE, Janecka IP, Schramm VL, Yonas H. A new method to predict safe resection of the internal carotid artery. Although the term MRND strictly implies a comprehensive dissection of levels I-V, in the context of thyroid cancer, dissection . The radical neck dissection was designed to ensure completecancer removal in individuals with very advanced cancers inthe neck. Common types of neck dissection surgery Modified Radical Neck Dissection (MRND) Removal of all lymph node groups routinely removed with preservation of one or more of the accessory nerve, sternomastoid muscle and internal jugular vein; Selective Neck Dissection (SND) Dissection then continues through the superior aspect of the SCM at the mastoid tip, allowing for en bloc removal of the specimen. Parkin DM, Bray F, Ferlay J, Pisani P. Global cancer statistics, 2002. MeSH I feel like its a lifeline. At this point in the dissection, the internal jugular vein and the spinal accessory nerve are identified and preserved, reflecting the lymph node-bearing tissue inferiorly with the surgical specimen. Brazilian Head and Neck Cancer Study Group. Argentinian surgeon Oswaldo Suarez was the first to describe functional neck dissection in 1963, now called modified radical neck dissection (MRND). [Neck dissection complications]. 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 .

These may be altered to suit the individual preferences of the operating surgeon: 15 blade scalpels Monopolar cautery with the protected tip Bipolar bayonet forceps Surgical laparotomy sponges Sterile saline for irrigation Suction Elastic stays The ipsilateral digastric is then skeletonized to the digastric tendon and back along the posterior digastric tendon until the facial vein is reached. These are based upon anatomic studies delineating drainage pathways from different head and neck subsites. Ipsilateral selective neck dissection (levels 2 4) or a modified radical neck dissection (1 5) is indicated for the N1 neck. As previously mentioned, a radical neck dissection is a major surgical procedure. The levels are identified by Roman numeral, increasing towards the chest. If these side effects are severe, a follow-up surgery may be performed to try to fix them. A modified radical neck dissection that preserves all of these structures is also referred to as a type III modified radical neck dissection (MRND), a functional neck dissection, or a Bocca neck dissection [ 8, 9 ]. The clinical team, assisted by the nursing staff, must make sure protocols are followed to avoid infections, hydration issues, and calorie intake. Boundary: Level VII is bounded superiorly by the inferior border of the suprasternal notch and inferiorly by the innominate artery. The surgical bed is irrigated with saline, inspected for hemostasis and chyle, and surgical drains are placed. Medially, the cervical rootlets provide the appropriate depth of dissection (superficial to the deep layer of the deep cervical fascia). This activity presents the causes, pathophysiology, indications, contraindications of head and neck cancer. Shaw HJ. Unable to load your collection due to an error, Unable to load your delegates due to an error. The anterior border of the SCM is identified, and the muscle is retracted posteriorly while dividing the fascia that ensheaths the muscle. Modified radical neck dissection type I (MRND-I): Lymph nodes from level I-V, ipsilateral sternocleidomastoid muscle, and internal jugular vein are removed, with preservation of the spinal accessory nerve. Certain primary parotid malignancies also warrant this operation. Included in this tissue, which extends from the collarbone (clavicle) inferiorly to the jawbone (mandible) superiorly are dozens of . RND includes resection of sternocleidomastoid muscle (SCM) and accessory nerve (XIn) and internal jugular vein (IJV). 1984 Jul;94(7):942-5. MND preserves SCM and/or XIn and/or IJV.

Explain common complications associated with radical neck dissections. Arch Otolaryngol Head Neck Surg. However, this operative procedure is not without significant morbidity, as it results in a cosmetic deformity and dysfunction of shoulder movement due to en bloc resection of the accessory nerve, sternocleidomastoid muscle, internal jugular vein, and the tail of the parotid gland. Superior Dissection:The fibrous fatty tissue of the submental triangle is dissected off the anterior bellies of the digastric muscles and the mylohyoid. While numerous modifications have been made to the originally described radical neck dissection to reduce morbidity, the procedure remains an oncologically sound procedure to remove the advanced cervical disease that involves the IJV, SCM, and CN XI. Modified radical neck dissection (MND) is a complicated operation. Head and neck cancers most commonly metastasize initially to the cervical nodal basins. As anatomic and oncologic understanding has improved, the neck dissection has become increasingly narrow in scope. Neck Dissection. The nodal packet is divided inferiorly at the level of the clavicle after mobilization of the omohyoid inferiorly. Modified radical neck dissection The removal of the cervical lymph nodes is the neck dissection 'neck dissection,' and various types of neck dissections 3. [5]For a neck dissection to fall intothe MRND classification, levels I-V must be removed, and at least one of the following structures must be preserved: spinal accessory nerve, sternocleidomastoid muscle, and internal jugular vein. Purpose The purpose of radical neck dissection is to remove lymph nodes and other structures in the head and neck that are likely or proven to be malignant. [3][4]This system divides the lymph nodes in the lateral aspect of the neck into five nodal levels, I through V, as described below.

This activity highlight the role of the healthcare team in managing patients with head and neck cancer. American Academy of Otolaryngology--Head and Neck Surgery. The modified radical neck dissection also removes levels I-V but spares at least one non-lymphatic structure (SCM, IJV, or CN XI). Selective neck dissection (SND) involves removal of some but not all of the cervical lymph node groups removed in the radical neck dissection. -, Weiss MH, Harrison LB, Isaacs RS. [Updated 2022 Oct 2]. A horizontal line extended from the inferior border of the cricoid divides levels Va (superior to cricoid) and Vb (inferior to cricoid). Even in the early 19th century, physicians were aware of the poor prognosis associated with cervical metastases in head and neck cancer. For patients with complex medical comorbidities, the expertise of hospitalists is invaluable in ensuring patients' other health parameters are maximized both before and after surgery. Just deep to the digastric tendon, CN XII is identified and protected. Identify the key anatomic relationships in the neck. She made about a 7" incision. Dr. Closure: Incision closure is in three layers: the first layer approximates the platysma anteriorly and the subcutaneous tissue laterally, and the second layer approximates the subcuticular layer. Sutures for vessel ligation (both regular and stick tie). The amount of tissue taken out depends on how much can safely be removed, and some surgeries remove all of the tissue from one side of the neck, including muscles, nerves, lymph nodes, and blood vessels. Removal of the cervical lymph nodes for oncologic reasons is termed a "neck dissection," and the surgery is tailored to address the lymph node basins at risk for metastatic spread depending on the site of the primary tumor. One method is to section the specimen at 5mm sequential intervals but retain its integrity by conserving . 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. - Definition, Causes & Removal, What Is Glaucoma? If available, a surgical assistant is recommended. [18][19], Currently, head and neck surgeons throughout the world use a variety of different cervical lymph node dissections for the surgical treatment of the neck in patients with cancer of the head and neck region. The selective neck dissection refers to any procedure which removes one or more levels of the neck based on patterns of cervical metastasis. ), Various pickups (Addson, Gerald, Cushing, DeBakey, etc. So my surgery was BIG, much bigger than just a neck. Finally, an extended neck dissection refers to any neck dissection that removes additional structures of lymph nodes from areas not addressed in radical neck dissection. Key structures and relationships: The phrenic nerve runs deep to the cervical rootlets and superficial to the anterior scalene muscle beneath the deep layer of the deep cervical fascia. The carotid sheath is identified deep to the muscle. We advise the use of the scalpelor scissors to dissect aroundthe mandibular branch rather thanelectrocautery as it may cause temporarydamage to the nerve. The omohyoid muscle is divided, and the external jugular vein can either be preserved or divided, depending upon the vascular needs of the reconstructive surgeon. 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. 346 lessons, {{courseNav.course.topics.length}} chapters | Anxiety and depression in patients with head and neck cancer: 6-month follow-up study. During this step of the operation, it is important to preserve the branches of the cervical plexus that innervate the levator scapulae muscle, unless the extent of the disease in the neck precludes it. Elective radiotherapy of the N0 neck to embrace either side and the retropharyngeal nodes is indicated. Lydiatt DD, Karrer FW, Lydiatt WM, Johnson PJ. Level VI is divided into left and right by the trachea. Tumor Boards, where all subspecialties and allied health practitioners meet to discuss and plan treatment for new cancer diagnoses are now the norm and the expectation. Level I (submental triangle is level Ia and submandibular triangles are level Ib) borders are: 2. The suprahyoid muscles are the digastrics, stylohyoid, mylohyoid, and geniohyoid.. If certain nerves are removed or damaged during the surgery, this can result in loss of feeling or movement of the tongue and/or lip as well as ear numbness. Modified radical neck dissections are classified as type I, II, or III based on which structures are saved. Finally, the facial artery is ligated as it crosses forward, under the posterior belly of the digastric muscle. The neck is hyper-extended with the use of a shoulder roll, and rotated to the opposite side. Create an account to start this course today. 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 in the shoulder. [1] A radical neck dissection removes the most tissue. I was in the hospital for 2 days before going home. [6]The types and indications of various types of neck dissection areas follows: 1. The IJV is then ligated high in the neck. Enjoy access to millions of ebooks, audiobooks, magazines, and more from Scribd. Modified Radical Neck Dissection (MRND): Removal of all lymph node groups routinely removed in an RND, but with preservation of one or more non-lymphatic structures (SAN, SCM, and IJV). Shah JP, Strong E, Spiro RH, Vikram B. Surgical grand rounds. Medial dissection:Thedissectionis continuedmediallyto expose the vagus nerve, the common carotid artery, and the internal jugular vein. Brain blood flow SPECT in temporary balloon occlusion of carotid and intracerebral arteries. Thesubmandibular gland is then dissected free from the mandible and reflected posteriorly, exposing the superior aspect of the IJV. The single most important factor affecting prognosis for squamous cell carcinoma is the status of the cervical lymph nodes. Other surgeons had advocated for the removal of the lymphatic tissue of the neck,but it was Dr. George Criles 1906 article that described en bloc resection of the cervical lymph nodes for a clinically positive nodal diseasethat is credited with the first description of the technique. The facial vein is ligated, and the remaining posterior digastric muscle is skeletonized. If the tumor mass is located low in the jugulodigastric region or the mid-jugularregion, the internal jugular vein is first ligated and divided superiorly. In contrast to the measured pace of refinements to the technique of neck dissection, the role of neck dissection in the management of regional disease across the entire gamut of histologies, from squamous cell carcinoma to cutaneous melanoma, to papillary thyroid carcinoma, is evolving rapidly. 's' : ''}}. Nursing staff who care for head and neck patients should be familiar with common postoperative complications so they can be identified in a timely manner. 1-6). [15], Incision: There are many historical incisions including the Latyshevsky and Freund, Mac Fee,Crile, Kocher, Schobinger, and Hockey stick, but in modern head & neck surgery, the operation is performed via a single incision placed in an existing neck skin crease midway down the neck. The nodal contents of level V are reflected medially and included with the nodes of levels II-IV. This can greatly increase vessel length available for microvascular reconstruction and should be discussed between the ablative and reconstructive surgeons preoperatively if it is oncologically sound to perform this dissection. Its like a teacher waved a magic wand and did the work for me. Modified radical neck dissection. Read this lesson to learn more about the procedure and its potential complications or side effects. The duct and submandibular ganglion are then ligated, preserving the lingual nerve. 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. Modern care of the cancer patient is by definition, multi-disciplinary. 2012 Dec 15;5(4):410-3. Allmembers of the treatment team should be familiar with head and neck cancer patients. Also, preparation of the neck dissection incisions must take into consideration any reconstructive effort required to repair the surgical defect created after the excision of the primary tumor. Key structures and relationships: Level II is divided into two parts by CN XI. The right recurrent laryngeal nerve courses more obliquely due to coursing around the innominate artery, while the left nerve has a more vertically oriented course after looping around the aorta. Babin RW, Panje WR. Radical Neck Dissection - All lymph nodes and tissues (muscle, nerves, blood vessels, and salivary gland) on the affected side are removed Modified Radical Neck Dissection - The lymph nodes are completely removed, while the remaining tissue is removed selectively Selective Neck Dissection - Only some of the lymph nodes and tissues are removed The facial vessels will once again be encountered on the anterior aspect of the submandibular gland and will require a second ligation. Mathews D, Walker BS, Purdy PD, Batjer H, Allen BC, Eckard DA, Devous MD, Bonte FJ. The radical neck dissection refers to the removal of levels I-V along with the SCM, IJV, and CN XI. Official report of the Academy's Committee for Head and Neck Surgery and Oncology. The fascia is then dissected off the anterior belly of the digastric muscle, and the specimen is retracted posteriorly, removing the fibrous fatty tissue containing lymph nodes lateral to the mylohyoid muscle. 2022 May;52(3):511-525.

Postero-lateral neck dissection: Removal of levels IIV, suboccipital, retro-auricular nodes withsparing of IJV, SCM, and SAN. Other surgeons had advocated for the removal of the lymphatic tissue of the neck, but it was Dr. George Criles 1906 article that described en bloc resection of the cervical lymph nodes for a clinically positive nodal disease that is credited with the first description of the technique. 2. The modified radical neck dissection uses the same incisions and elevation of subplatysmal flaps as the radical neck dissection. Level Ib is bordered by the anterior belly of the digastric muscle anteriorly, the posterior belly of the digastric muscle posteriorly, the posterior edge of the submandibular glands laterally, and the mandible superiorly. Nodal Drainage Patterns by Head and Neck Subsite. Level IV (lower jugular lymph nodes) borders are: 5. Boundary: Level III is bounded by the posterior border of the SCM laterally, the lateral border of the sternohyoid medially, the hyoid superiorly, and the inferior border of the cricoid cartilage inferiorly. The surgeon should always consider whether an operation may be detrimental to the overall health of the patient due to underlying comorbidities and the inherent stressors of surgery.[14][15]. Lecturer at Department of Oral Medicine and Periodontology, Faculty of Dental Sciences, University of Peradeniya The surgeon must remain very vigilant on the left side to be able toidentify thoracic duct, which arches downward and forward from behind the common carotid to open into the internal jugular vein, the subclavian vein, or the angle formed by the junction of these two vessels. Rodrigo JP, Grilli G, Shah JP, Medina JE, Robbins KT, Takes RP, Hamoir M, Kowalski LP, Surez C, Lpez F, Quer M, Boedeker CC, de Bree R, Coskun H, Rinaldo A, Silver CE, Ferlito A. They include wound dehiscence, percutaneous or pharyngocutaneous fistula, infection, hematoma, sialocele, and chylefistula. The reported incidence varies between 1% and 2.5%. Dissection then continues through the inferior 1/3 of the parotid--or parotid tail-- being careful to avoid injury to the main trunk of the facial nerve. The evaluation, indications, and contraindications of selective neck dissections. In: StatPearls [Internet]. (Figure I). When the dissection reaches the posterior border of the mylohyoid, this is retracted anteriorly, exposing the lingual nerve and the submandibular gland ductare divided. The brachial plexus may be identified in the lateral, inferior portion of this dissection between the anterior and middle scalenes and should be protected. The American Cancer Society reports that 40% of patients with squamous carcinoma of the oral cavity and pharynx present with regional metastases to the cervical lymph nodes. Avoidance of paralytics is advocated at this point in the operation by some surgeons. The four main types of neck dissection are: Radical neck dissection: This is the standard procedure for neck dissection, and all other forms of neck dissections are a modification of this procedure.

Care should be taken to ensure that the head does not "hang" and is supported to prevent neck injury. Please enable it to take advantage of the complete set of features! Indications for MRND-Iis in bulky nodal disease with extracapsular spread involving the SCM and IJ, where the accessory nerve is free of disease. [Neck dissection complications]. The resulting denervation of the trapezius muscle causes destabilization of the scapula with progressive flaring at the vertebral border, drooping, and lateral and anterior rotation. modified radical neck dissection: A spectrum of head and neck surgeries performed on a person requiring excision of tissue involved by cancer, usually squamous cell carcinoma. Sometimes the blood vessels, muscles and the nerves (neck) are spared. Key structures and relationships: The recurrent laryngeal nerve runs through level VI. The internal jugular vein can almost always be spared with meticulous technique, but if resection is necessary, it is important to obtain circumferential control of the vessel proximally and distally with vessel loops before cross-clamping and dividing it. JAMA. Side effects vary based on which structures are removed. On the 13th day after surgery, the patient was studied with videofluoroscopy, which showed absence of fistula, The fibro-fatty tissuemedialto the muscle is incised, exposing the splenius capitis and the levator scapulae muscles. Side effects vary based on what structures are removed. You may have a neck dissection if there is a high risk of the cancer spreading to the lymph nodes in your neck. Removing part or all of the sternocleidomastoid muscle can physically change the appearance of the neck and make moving the head forward more difficult. Boccaand Suarezindependently in the 1960s. Various incisions can be used, but the most commoninclude the "hockey stick" incision from the mastoid tip extending inferiorly and then curving anteriorly into a midline neck crease at least two fingerbreadths below the mandible. All patients should have a complete oncologic workup completed prior to surgery. Modified radical neck dissection involves the removal of all lymph nodes typically removed in the RND, with sparing or preservation of at least one of the following structures: SAN, IJV, SCM. I would definitely recommend Study.com to my colleagues. Additional, specialized, instruments are at the surgeon's preference and can include McCabe nerve dissectors, nerve hooks, harmonic scalpels, 0.9mm forceps, Munion right-angle clamps, and many others. Chylous fistula. This is an extensive surgery, so it's usually done once the cancer has already spread around the tissues in the head or neck, but not after cancer has spread to other parts of the body; removing the tissues is the most successful way to stop the cancer from spreading to other regions. HHS Vulnerability Disclosure, Help End results of a prospective trial on elective lateral neck dissection vs type III modified radical neck dissection in the management of supraglottic and transglottic carcinomas. Finally, the nodal packet is dissected free from the bifurcation of the IJV and common facial vein, allowing for en bloc removal of levels I-V. -, Shedd DP. Finally, an extended neck dissection refers to any neck dissection that removes additional structures of lymph nodes from areas not addressed in radical neck dissection. Any patient on anti-coagulation needs to have a clear plan for the management of this medication perioperatively. This might also be called a partial neck dissection. It is performed when the cancer has spread widely in the neck. Shedd DP. Alternately, the facial vein and marginal mandibular nerves can be skeletonized and preserved individually. Boundary: Level Ia (a midline structure) is bordered by the bilateral anterior bellies of the digastric muscles laterally, the hyoid inferiorly, and the mandible superiorly. (PDF) Neck Dissection Techniques and Complications Neck Dissection Techniques and Complications Authors: Jaimanti Bakshi Postgraduate Institute of Medical Education and Research Naresh K Panda. The site is secure. If the skin incisions have the proper design, the carotid seldom becomes exposed in the absence of a salivary fistula. The procedure removed all lymph nodes in the lateral neck (now known as levels I-V) and the spinal accessory nerve (CN XI), internal jugular vein (IJV), sternocleidomastoid muscle (SCM) along with several other surrounding structures including the tail of the parotid gland. Radical en-block procedure was suggested by Crile for management of metastatic cervical cancer but since then many modifications in surgical procedures and flap design have been documented in the past [].Nowadays many conservative approaches are advocated for preservation of Spinal .

The most notable sequelae observed in patients who have undergone a radical neck dissection arerelated to the removal of the spinal accessory nerve. Attention is then turned to the contralateral anterior digastric. Modified radical neck dissection To describe the lymph nodes of the neck for neck dissection, the neck is divided into 6 areas called Levels. In 2002, the American Academy of Otolaryngology-Head and Neck Surgery proposed a standardized classification system for naming the various neck dissections in use which is still in use today. This activity reviews the indications and procedural steps for radical neck dissection and briefly discusses other variants of the neck dissection for head and neck cancer. The procedure is indicated in N0 neck for SCC of the lateral tongue, oral cavity, anterior floor of mouth, or for N1 disease in these primary sites.[10]. Neck dissection: current status and future possibilities. At the posterior border of the submandibular gland, the facial artery is identifiedandmay be ligated or traced through the submandibular gland and left intact. The SlideShare family just got bigger. Modified radical neck dissection type 3: Lymph nodes from level I-V undergo removal, with preservation of sternocleidomastoid muscle, internal jugular vein and spinal accessory nerve.
