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). [12], The unresectable disease is an absolute contraindication to performing a neck dissection. 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) Modifiedradical neck dissection type III (MRND-III): Lymph nodes from level I-V undergo removal, with preservation of SCM, IJV, andSCM. Any patient on anti-coagulation needs to have a clear plan for the management of this medication perioperatively. All the tissue on the side of the neck from the jawbone to the collarbone is removed. In: StatPearls [Internet]. RND includes resection of sternocleidomastoid muscle (SCM) and accessory nerve (XIn) and internal jugular vein (IJV). For purposes of lymph node dissection, the unilateral neck is classified by discreet anatomic . The work of Henry T. Butlin, an early head and neck surgeon. 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. Medially, the cervical rootlets provide the appropriate depth of dissection (superficial to the deep layer of the deep cervical fascia). Continuing Education Activity The history of the neck dissection for head and neck cancer stretchesback nearly two centuries. -. Level IB is then dissected free from the mandible and reflected inferiorly. In less advanced disease, the modified radical neck dissection and some cases selective neck dissection have replaced this procedure. These are based upon anatomic studies delineating drainage pathways from different head and neck subsites. {{courseNav.course.mDynamicIntFields.lessonCount}}, What Is a Goiter? A simple system of nomenclature has been suggested which allows specification of the node levels dissected and the structures preserved. Modifications to the radical neck dissection include the following: Type I: The spinal accessory nerve is preserved. Kerawala CJ, Heliotos M. Prevention of complications in neck dissection. 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. Next, the marginal mandibular nerve is identified and protectedby elevating the fascia overlying the submandibular gland. CN XI often gives off a small branch to the trapezius prior to entering the SCM.[11]. A radical neck dissection is the most thorough of all the types of neck dissections. In a type, I MRND CN XI is spared. A selective neck dissection is also called a functional neck dissection. 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. 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. Parkin DM, Bray F, Ferlay J, Pisani P. Global cancer statistics, 2002. Contributed by Dr. Shekhar Gogna. Consensus statement on the classification and terminology of neck dissection. By George Crile. The muscle is skeletonized from the mandible to the hyoid, and the level IA contents are rolled towards the ipsilateral anterior digastric. Many surgeons prefer to avoid this as it places a relatively hypo-perfused tri-point directly atop the carotid vessels after closure. Modified radical neck dissection. 7.

The omohyoid muscle, which lies just superficial to the IJV,is also divided. 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. 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. If there is a concern for significant airway obstruction due to disease, anatomy, or pre-existing treatment (ie, previous radiation or cervical spine surgery), awake fiberoptic intubation or awake tracheostomy may need to be planned and coordinated with the anesthesia team. In level IIb of the neck, the lymphatic packet is dissected free from the deep layer of the deep cervical fascia and passed under CN. The carotid sheath is identified deep to the muscle. Historically, there were named subtypes of selective neck dissections: supraomohyoid: levels I-III extended supraomohyoid (anterolateral): levels I-IV posterolateral: levels II-V, suboccipital, postauricular On the 13th day after surgery, the patient was studied with videofluoroscopy, which showed absence of fistula, The risk of a life threatening complication is negligible, but there are risk to the procedure.

The lymph nodes in the neck are divided into seven levels by anatomic landmarks. Inferior dissection:The dissection is continued posteriorly and inferiorly along the anterior border of the trapezius muscle. 2. This should include a biopsy with a diagnosis of cancer, imaging of the head and neck, and PET-CT or chest CT to evaluate distant metastasis and accurately stage the disease. These physical changes result in a syndrome of pain, weakness, and deformity of the shoulder girdle commonly associated with the radical neck dissection. However, this procedure resulted in significant cosmetic deformity and loss of function. Patterns of cervical lymph node metastasis from squamous carcinomas of the upper aerodigestive tract. The credit for neck dissection as a curative procedure for cervical metastases belongs to George Washington Crile from the Cleveland Clinic. Modified radical type II: En bloc removal of the lymph-node-bearing tissues of one side of the neck, includes sternocleidomastoid Modified radical type III: En bloc removal of the lymph-node-bearing tissues of one side of the neck. Careers. It is performed when the cancer has spread widely in the neck. Radical neck dissection was first described by Crile in 1906 and popularized by Hayes Martin and still2 and it was the main surgical modality of metastatic cervical lymphadenopathy secondary to squamous cell carcino- ma (SCC) until the last third of the 20th century. The anterior border of the SCM is identified, and the muscle is retracted posteriorly while dividing the fascia that ensheaths the muscle. Over the lifetime, 492 publication(s) have been published within this topic receiving 11702 citation(s). The fibro-fatty tissue in this region is then gently pushed in an upward direction, exposing the brachial plexus, the scalenus anterior muscle, and the phrenic nerve (Fig. The duct and submandibular ganglion are then ligated, preserving the lingual nerve. 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. The nerve is then skeletonized superiorly to the posterior belly of the digastric muscle and posteriorly to the trapezius. Level: I (submental and submandibular nodes). 's' : ''}}. The facial artery and vein are ligated on the inferior aspect of the submandibular gland. A procedure called a modified radical neck dissection (or anterolateral neck dissection or comprehensive neck dissection), in untreated patients, should only be performed in instances of ultrasound with fine needle aspiration confirmed thyroid cancer spread to lymph nodes on the side of the neck.

The functional neck dissection for lymph node neck metastasis in oral carcinoma. This nerve lies just anterior to the submandibular fascia and superficial to the posterior facial vein. As a result, removal of the cervical lymph nodes is an important component of the standard of care for many head and neck cancers. MRND-III isindicated in metastatic disease with limited extracapsular spread and the IJ, SCM, and accessory nerve can all be dissected free.[8][9]. [11], There are no absolute contraindications to neck dissection beyond those that make a patient unfit for general anesthesia and resection, with one exception: unresectable disease. Muscles in the front of the neck are the suprahyoid and infrahyoid muscles and the anterior vertebral muscles. 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. 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 Superior Dissection:The fibrous fatty tissue of the submental triangle is dissected off the anterior bellies of the digastric muscles and the mylohyoid. 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]. eCollection 2018. If the nodes from zones I through V are removed and one of these three structures is preserved, it is called a modified radical neck dissection.

Official report of the Academy's Committee for Head and Neck Surgery and Oncology. The facial vessels will once again be encountered on the anterior aspect of the submandibular gland and will require a second ligation. Identifying Marginal mandibular nerve: Careful identification of the marginal mandibular branch of the facial nerve is crucial. 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. 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 .

I was in the hospital for 2 days before going home. The flap is elevated up to the anterior border of the trapezius muscle. Identify the key anatomic relationships in the neck. Tumor encasement of the carotid artery (NOTE: many authors view this as 'unresectable disease,' as resection and grafting does not confer a survival or local control advantage, even if it is technically possible), Fixed neck mass in the deep neck muscles, prevertebral fascia, and/or skull base involvement (unresectable disease). Modified radical neck dissection The removal of the cervical lymph nodes is the neck dissection 'neck dissection,' and various types of neck dissections 3. Level VI is divided into left and right by the trachea. Babin RW, Panje WR. Academys classification. 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. 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.

A neck dissection is a type of surgery in which groups of lymph nodes in the neck are removed to determine if they contain cancer cells. If the carotid artery may be sacrificed, preoperative evaluation with carotid artery balloon occlusion studies with xenon CT or SPECT-CT imaging should be undertaken to determine the role of carotid reconstruction. The neck is hyper-extended with the use of a shoulder roll, and rotated to the opposite side. By George Crile.

Chintamani Ten Commandments of Safe and Optimum Neck Dissections for Cancer. 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. [2] Therefore, the management of cervical lymph nodes is a vital component in the overall treatment plan for patients with squamous cell carcinoma of the head and neck. A radical neck dissection removes the most tissue. 2012 Dec 15;5(4):410-3. 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. Ipsilateral radical neck dissection or selective neck dissection (levels 2 5) is indicated for the N2/3 neck.

Supraomohyoid neck dissection (SOHD): Lymph nodes removed are Levels III, with sparing of IJV, SCM, and accessory nerve. 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 surgery may include removing important structures, such as the sternocleidomastoid muscle, which is responsible for flexing the head, internal jugular vein, and salivary gland. The classification of cervical lymph nodes is according to the system developed at Memorial Sloan-Kettering Cancer Center in the 1930s.

The ansa cervicalis is seen running across the IJV at this point of the dissection and may be sacrificed. Level VII:(superior mediastinal lymph nodes) borders are: Before discussing the indications for neck dissection and the operative technique, it is essential to review the brief background, history, and types of neck dissection. Head and neck surgery for cancer is a major undertaking with potentially enormous morbidity. Alternately, the facial artery and vein can be dissected through the substance of the submandibular gland to increase the length of these vessels available for microvascular anastomosis, or if a submental flap is planned. Carotid artery involvement may be considered either an absolute or relative contraindication to surgery. The IJV is then ligated high in the neck. A modification of the MacFee incisions for neck dissection. This is the most common type of neck dissection. With proximal and distal control of the IVJ, the inferior end of the internal jugular is isolated and ligated, taking care to ensure that neither the carotid nor the vagal nerve (CN X) is included in the ligation. The reported incidence varies between 1% and 2.5%. Access free multiple choice questions on this topic. The 5 levels are labeled using Roman numerals (I, II, III, IV, and V). To prevent a chyle leak, the surgeon must also remember that the thoracic duct may have multiple connections at its upper end and that at the base of the neck it usually receives a jugular, a subclavian, and perhaps other minor lymphatic trunks, which must be individuallyligated or clipped. Shah JP, Strong E, Spiro RH, Vikram B. Surgical grand rounds. If the thoracic duct is violated, clips or suture should be used to prevent a persistent chyle leak. General endotracheal anesthesia is essential for performing a neck dissection, and the use of paralytic agents should be discussed between the surgeon and anesthetist. The clinical team, assisted by the nursing staff, must make sure protocols are followed to avoid infections, hydration issues, and calorie intake. Argentinian surgeon Oswaldo Suarez was the first to describe functional neck dissection in 1963, now called modified radical neck dissection (MRND). The most notable sequelae observed in patients who have undergone a radical neck dissection arerelated to the removal of the spinal accessory nerve. A thorough understanding of the critical structures, fascial layers, and cervical lymph node drainage patterns in the neck is key to performing safe and oncologically sound surgery.

An operating surgeon, an assistant surgeon (resident/registrar, another surgeon, or a certified first-assistant), scrub nurse, circulating nurse, and the anesthetist. 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 . Krol E, Brandt CT, Blakeslee-Carter J, Ahanchi SS, Dexter DJ, Karakla D, Panneton JM. 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. Arch Otolaryngol Head Neck Surg. [1]The single most important factor affecting prognosis for squamous cell carcinoma is the status of the cervical lymph nodes. The Radical Neck Dissection described initially by George Crile in 1906 involves removal of lymph node levels I-V, the sternocleidomastoid muscle, the internal jugular vein and the spinal accessory nerve. The loss of trapezius function decreases the patients ability to abduct the shoulder above 90 degrees at the shoulder. Bocca and Suarez independently in the 1960s. Copyright 2022, StatPearls Publishing LLC. The radical neck dissection refers to the removal of levels I-V along with the SCM, IJV, and CN XI. You may have a neck dissection if there is a high risk of the cancer spreading to the lymph nodes in your neck. The transverse cervical artery will also be present in this area and should be avoided. 7. Modified radical neck dissection (Figure 4, Figure 5, and Figure 6) refers to the excision of all lymph nodes routinely removed by the radical neck dissection with preservation of 1 or more nonlymphatic structures (ie, the SAN, internal jugular vein, and SCM). The drain(s) should not rest immediately over the carotid artery or in the area ofthe thoracic duct, or atop any named nerve. The lymph nodes in the central compartmentare in category level VI, and those in the superior anterior mediastinum are level VII. Radical neck dissection (RND): Lymph nodes from level I-V, ipsilateral sternocleidomastoid muscle (SCM), internal jugular vein (IJV), and spinal accessorynerve (SAN) undergo removal (the parotid tail is rarely included in modern RND). Indications for MRND-II include bulky nodal disease with SCM involvement but sparing the IJ or accessory nerve. Cervical rootlets are often preserved, though they can also be divided[17], while preserving the deep layer of the deep cervical fascia overlying the levator scapulae and scalene musculature to protect the phrenic nerve and brachial plexus. bilateral neck dissection (modified radical type III) and right hemithyroidectomy was performed; the single stage reconstruction was done with the traditional ileocolic free flap (reconstruction type I).

You might have a selective neck dissection if the doctors know or suspect that only a small number of lymph nodes contain cancer. 2009 Sep;135(9):876-80. doi: 10.1001/archoto.2009.119. The care of head and neck cancer patients requires a truly multidisciplinary effort in order to maximize patient outcomes. 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. By accepting, you agree to the updated privacy policy. Modified radical neck dissection To describe the lymph nodes of the neck for neck dissection, the neck is divided into 6 areas called Levels. Care is taken to avoid injury to the vagus nerve during the dissection. Modified radical neck dissection (MND) is a complicated operation. 346 lessons, {{courseNav.course.topics.length}} chapters | 8600 Rockville Pike Refers to any type of cervical lymphadenectomy where . Trifurcate incisions were popular in the past, and can still be used in the case of bulky posterior neck disease, but care should be taken to not place the trifurcation over the carotid artery.[16][17]. In type II, MRND CN XI and the IJV are spared. 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. Care should be taken to avoid communication with a tracheostomy if one has been placed.

A new method to predict safe resection of the internal carotid artery. This activity highlight the role of the healthcare team in managing patients with head and neck cancer. If these side effects are severe, a follow-up surgery may be performed to try to fix them. Level IIb is bounded by the posterior edge of the SCM laterally, CN XI anteriorly, the floor of the neck posteriorly, the skull base superiorly, and the hyoid inferiorly. Modified radical 2. Ann Clin Lab Sci. -, Weiss MH, Harrison LB, Isaacs RS. Management depends on the time of onset of the fistula, on the amount of chyle drainage in 24 hours, and the presence or absence of accumulation of chyle under the skin flaps. HHS Vulnerability Disclosure, Help Modified radical neck dissection removes lymph nodes from levels I to V, but keeps one or more of the following - internal jugular vein, sternocleidomastoid muscle or spinal accessory nerve. I would definitely recommend Study.com to my colleagues. [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 radical neck dissection refers to the removal of levels I-V along with the SCM, IJV, and CN XI. The most important aspects of success involve interprofessional care of the patient. She took 94 lymph nodes out. The https:// ensures that you are connecting to the [5][6][7], In 2002, the American Academy of Otolaryngology-Head and Neck Surgery proposed a standardized classification system for naming the various neck dissections in usewhich is still in use today. - Definition, Complications & Recovery, What Is Ultrasonography? 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. This might also be called a partial neck dissection. These different types of neck dissections refer to the amount and location of nodes removed or the secondary structures removed or preserved. Review the indications for performing radical neck dissection, modified radical neck dissection, and selective neck dissection. There is no definitive evidence to suggest this improves survival, but is occasionally performed if risk of carotid blowout is felt to be high. Selective neck dissection is an operative procedure designed to remove cervical lymph nodes at risk for involvement by metastatic disease and is characterized by the preservation of one or more lymph node groups that are routinely removed in radical neck dissections. 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. 1) Radical neck dissection (RND) 2) Modified radical neck dissection (MRND) 3) Selective neck dissection (SND) Supra-omohyoid type Lateral type Posterolateral type Anterior compartment type 4) Extended radical neck dissection. Larsen MH, Lorenzen MM, Bakholdt V, Srensen JA.
