Selective neck dissection in surgically treated head and neck squamous cell carcinoma patients with a clinically positive neck: Systematic review. Neck dissection is one of the routine surgical procedures performed by the head and neck surgeons. 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. Inferiorly, the phrenic nerve isidentifiedand protected by not violating the deep fascia of the floor of the neck overlying the brachial plexus and muscles. Head and neck cancers most commonly metastasize initially to the cervical nodal basins. The ansa cervicalis is seen running across the IJV at this point of the dissection and may be sacrificed. The following is a list of key instruments used during neck dissections at the author's home institution. It will be necessary to ligate numerous branches of the IJ to accomplish this elevation. Thesubmandibular gland is then dissected free from the mandible and reflected posteriorly, exposing the superior aspect of the IJV. 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 SlideShare family just got bigger. 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. 7. Anxiety and depression in patients with head and neck cancer: 6-month follow-up study. The marginal mandibular branch of the facial nerve can be found in the fascia overlying the submandibular gland superficial to the facial vessels and deep to the platysma. 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.

Various retractors (Army-Navy, Langenbeck, etc. We'll review the major issues. Selective neck dissection (SND) involves removal of some but not all of the cervical lymph node groups removed in the radical neck dissection. Elective radiotherapy of the N0 neck to embrace either side and the retropharyngeal nodes is indicated. The tail of the parotid gland is elevated off of the SCM and deep structures, and the sternocleidomastoid muscle is then incised close to its insertion in the mastoid process. Superior - the lower border of the body of the mandible; Posterior - posterior border of the sternocleidomastoid, Posterior - the anterior border of the trapezius, Anterior - the posterior border of the sternocleidomastoid, Lateral- medial border of the carotid sheath on either side, Severe cardiopulmonary disease, COPD with poor functional status, Preoperative imaging showing deep infiltration of the tumor in the prevertebral space, scalene muscles, levator scapula muscle, phrenic nerve, and brachial plexus are not suitable candidates. Indications for MRND-Iis in bulky nodal disease with extracapsular spread involving the SCM and IJ, where the accessory nerve is free of disease. At this time, the surgeon may choose to save the root of CN XI and the trapezius branch. The work of Henry T. Butlin, an early head and neck surgeon. The greater auricular nerve and the external jugular vein should be identifiedcarefully and preserved. There are 3 types of Neck Dissections: Radical: Includes Levels I through V, sternocleidomastoid muscle, internal jugular vein, and spinal accessory nerve (If you receive a radical neck dissection, please contact an attending for assistance) And if the operation does not involve all five zones, it is called a selective neck dissection. Sisli Etfal Hastan Tip Bul. Wistermayer P, Anderson KG. All patients should have a complete oncologic workup completed prior to surgery.

Certain primary parotid malignancies also warrant this operation. Synchronous bilateral radical neck dissections, in which both internal jugular veins undergo ligation, can result in the development of facial edema, cerebral edema, or both; blindness; and hypoxia. [1], Over time, the procedure has been modified to reduce morbidity while maintaining oncologic efficacy. 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. The primary tumor that is uncontrollable. 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. TheIJV will be identified as superficial and lateral to the carotid. In type III MRND CN XI, the IJV and the SCM are all spared.

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. 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]. The submandibular gland andassociated lymph nodes are then reflected superiorly and raised off of the mylohyoid. The most common complications from radical neck dissections include bleeding, post-surgical infections, and adverse reactions to medication. The anterior border of the SCM is identified, and the muscle is retracted posteriorly while dividing the fascia that ensheaths the muscle.

Consensus statement on the classification and terminology of neck dissection. The loss of trapezius function decreases the patients ability to abduct the shoulder above 90 degrees at the shoulder. 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]. Federal government websites often end in .gov or .mil. The modified radical neck dissection uses the same incisions and elevation of subplatysmal flaps as the radical neck dissection.
