supraomohyoid neck dissection steps

Identify the carotid sheath and vagus nerve as depicted in the images below. The supraomohyoid neck dissection is a selective cervical node dissection that removes the contents of the submental and submandibular triangles (lymph node level I), the jugulodigastric and jugulo-omohyoid lymph node groups, and the lymph node-bearing tissues located anterior to the cutaneous branches of the cervical plexus and above the omohyoid muscle (lymph node levels II and III). After completion of all of the above, dissect and displace inferiorly the submental fatty tissue, submandibular nodes, and submandibular gland. Spinal accessory nerve (SAN) dysfunction and related shoulder disability are common consequences of supraomohyoid neck dissection (SOHND). [Medline]. Kowalski L P, Sanabria A. Elective neck dissection in oral carcinoma: a critical review of the evidence. In summary: The indications to supraomohyoid neck dissection are SCC of the oral cavity, T1-T4, and N0. Supraomohyoid neck dissection is both diagnostic and therapeutic in patients with N0. However, the treatment role of supraomohyoid neck dissection in patients with positive neck disease (N+) is more controversial. Tumor spread beyond the capsule of an LN is the most important prognostic factor related to recurrence in the neck. Supraomohyoid neck dissection is not indicated in fixed masses. A Foley catheter is unnecessary during supraomohyoid neck dissection. This is disadvantageous because the compressive dressing leaves flaps unavailable for inspection, which is the best way to monitor for hematoma formation. Airway compromise or marginal compromise is not uncommon in patients with head and neck cancer. Clinical Case, You are being redirected to Lim YC, Song MH, Kim SC, Kim KM, Choi EC. https://profreg.medscape.com/px/getpracticeprofile.do?method=getProfessionalProfile&urlCache=aHR0cHM6Ly9lbWVkaWNpbmUubWVkc2NhcGUuY29tL2FydGljbGUvODUwMTk1LXRyZWF0bWVudA==. The mylohyoid muscle is retracted and elevated anteriorly. In a neck with multiple node metastasis or extracapsular spread, the recurrence rate is 12-25%. Patients with large leaks require enteral or parenteral feeding, controlled exteriorization of the fistula, and local care before closure of local skin or myocutaneous flaps. Careful dissection avoids injury to the hypoglossal and lingual nerves, which are located deep to the fascia on the floor of the submandibular triangle. Author information: (1)Department of Maxillofacial and Plastic Surgery, Centre Hospitalier Universitaire de Bordeaux, France. Figure 7: Recommended surgical steps for supraomo-hyoid neck dissection. Occasionally, ligating the carotid artery beneath the clavicle is necessary. Prevention and planning are mandatory. [Medline]. If the hematoma is recognized and treated early, no adverse consequences ensue. Volume One: 25-92. A foray into neck anatomy, comments welcome for improvement. Refers to the removal of lymph nodes contained in levels I-III. The pathologist looks systematically for extracapsular spread, which is commonly encountered. This particular technique should be taught and discussed with residents in their first cases. Figure 17 STEP 5 LEVEL IV DISSECTION With a lateral neck dissection, Level IV is dissected by applying traction to the fibrofatty tissue deep to the omohyoid Oral Oncol. Shoulder physical therapy has been ordered if needed. [Medline]. Neck dissection: past, present and future?. Shah JP, Andersen PE. Identify and preserve the superior thyroid artery where it originates from the external carotid artery. Edema reaches a maximum at POD 7 and progressively decreases in a few weeks with conservative management. Exposure and identification of the carotid-internal jugular axis has been accomplished. Minimally invasive surgery with the assistance of endoscopic and robotic instrumentation has been tried in head and neck cancer management, including neck dissection for cervical metastatic disease. Adequate ligations and transfixion sutures are mandatory. (The author's institution does not follow this practice.). 8600 Rockville Pike If other surgical procedures were performed in addition to supraomohyoid neck dissection, the discharge day varies according to the progress and condition of the patient. [Medline]. When the supraomohyoid neck dissection is performed without opening the oral cavity or aerodigestive tract, major complications are unlikely. Head Neck. 47(1):5-9. 2008/05. The dissection continues inferiorly with incision of the fibroadipose tissue along the posterior border of the SCM muscle to the level of the omohyoid muscle. Otorrinolaringol. 1999 Jun. Crile first described the radical neck dissection in the early 1900s, but modifications… The … 128(3):268-73. Ital. 36(3):425-30. Dissection with an intermediate hemostat placed 2-3 finger breadths below the posterior belly of the digastric muscle, at the point where the accessory nerve enters the SCM muscle, (as seen in the image below) encounters the nerve directly with sight or indirectly with stimulation. In a neck with single node metastasis without capsular spread, the recurrence rate is 10%. Medina JE. Carotid sinus reflux: Hypotension due to carotid sinus reflux may occur upon dissection around the carotid bifurcation. Follow the superior belly of the omohyoid muscle to the hyoid bone. Position the patient in reverse Trendelenberg s position with neck extended at atlanto-axial joint and head elevated 10 degree above the table. Endoscopic supraomohyoid neck dissection via a retroauricular or modified facelift approach: preliminary results. All irradiated tissues are more susceptible to infection because of ischemia and hypoxemia. Facial edema: Facial edema can occur even if a single IJV remains, particularly in patients with previous irradiation therapy.

Yanai Y, Sugiura T, Imajyo I, Yoshihama N, Akimoto N, Kobayashi Y, Hayashi K, Fujinaga T, Shirasuna K, Takenoshita Y, Mori Y. J Oncol. Use Vicryl or Dexon sutures in high-risk patients. Patients may be administered usual medications up to midnight before the surgical procedure. Define and standardize indications for the N+ neck. Ensure that Hemovac suction tubes or drains function properly. Carotid artery rupture is rare after supraomohyoid neck dissection. 2008 Feb 15. Because of a high risk of recurrence, radiation therapy is recommended for patients who have positive histologic findings in the neck and multiple node metastasis or extracapsular spread. Hanasono MM, Kunda LD, Segall GM, Ku GH, Terris DJ. [Medline]. Guo CB, Feng Z, Zhang JG, Peng X, Cai ZG, Mao C, et al. 585-686. It is also called anterolateral neck dissection. Careful attention to anatomy, hemostasis with an electrocautery unit or bipolar forceps, and use of clamps and suture ligation has allowed an almost bloodless neck operation. After this interval, the patient can be seen yearly. Stokkel MP, Terhaard CH, Hordijk GJ, van Rijk PP. In a difficult but not obstructed airway, the anesthetist may perform an awake intubation with the assistance of a flexible nasopharyngolaryngoscopy to accomplish a nasotracheal intubation. The peeling of the nodal tissue over the internal jugular vein (IJV) has been partially done in the picture. If the airway is obstructed, performing a tracheotomy with the patient under local anesthesia is preferred. Educational objectives: To understand the step-by-step approach to the performance of a supraomohyoid and lateral neck dissection and the management of malignancies of the upper aerodigestive tract. The spinal accessory nerve is preserved in the supraomohyoid neck dissection. The posterior limit of the dissection is marked by the cutaneous branches of the cervical plexus and the posterior border of the sternocleidomastoid muscle. Definitive treatment for carotid artery rupture includes the following measures: Ligate the carotid artery. Reinspect the area before completing the surgery. The accessory nerve is localized in the upper portion of the SCM muscle during the peeling maneuver. If skin flap necrosis occurs and the carotid is not exposed, a conservative approach is mandatory. Therefore, in one third of patients, the accessory nerve passes medial to the IJV and can be traumatized by any technical error. Vol. Other factors, such as poor general health, chronic malnutrition, alcoholism, diabetes mellitus, advanced age, and systemic illness, increase the percentage rate of complications. Operative Otolaryngology Head and Neck Surgery. Careers.

Leave the external jugular vein and the greater auricular nerve on the SCM muscle. Mansoor Khan Resident Plastic Surgery
2. Ferlito A, Rinaldo A, Robbins KT, Silver CE. 14(4):1002-14. Identify, clamp, and ligate the branches of the internal jugular vein. [Medline]. Traction with the surgeon's fingers and countertraction by the assistant with 2 double skin hooks are helpful in this maneuver. Face should be turned to the opposite side of the Salami A, Dellepiane M, Bavazzano M, Crippa B, Mora F, Mora R. New trends in head and neck surgery: a prospective evaluation of the Harmonic Scalpel. Place attention on the posterior corner formed by the posterior belly of the digastric muscle and the SCM muscle, which are retracted. Today, major vessel trauma, laceration, tear, or transection (eg, IJV, junction of IJV and subclavian and/or carotid arteries) is a rare occurrence. [Medline]. Consider and evaluate the following, taking careful documentation: Results of physical examination (including head and neck findings), Medical history (eg, medication allergies; hypertension, diabetes mellitus, cardiopulmonary disease, and other chronic illnesses; previous surgeries; radiation therapy), All test results, including those of biopsy and FNAB, Informed consent, with risks and complications fully discussed with the patient, Summarized problem and treatment plan, including alternatives plans, Patient's ability to open the mouth enough for intubation. resects fat and lymph nodes from the submental triangle (Level Ia). Overall survival (OS) and neck control rates (NCR) were investigated according to the treatment modality. July 2002. Ask the anesthesiologist to apply positive pressure to determine if further leaking is present. Irrigate the surgical field with isotonic sodium chloride solution, and, if any source of bleeding is found, ligate, suture, or electrocauterize to achieve hemostasis. Elevation posterior to the SCM muscles is unnecessary. Adequate exposure (both proximally and distally) to the source of bleeding and contaminated or infected areas helps prevent a second rupture. 33(3):445-50. Spinal accessory nerve (SAN) dysfunction and related shoulder disability are common consequences of supraomohyoid neck dissection (SOHND). Surgical technique modification. Therefore, false-positive and false-negative results are common. The decision between flap coverage and secondary healing is then made. You can change your ad preferences anytime. Supraomohyoid neck dissection/definition. Meticulous hemostasis during the surgical procedure is mandatory. Occasionally, the common facial vein must be divided; this is accomplished by preserving a stump of the IJV to avoid a narrowing of the main vein. Selection of treatment modality is a controversial subject because the decision to preserve a particular group of nodes remains intraoperative and is based on the surgeon's or pathologist's findings. A feeding gastrostomy tube is sometimes recommended for adequate nutrition. Is it worthy? Resection of the medial half of the clavicle is necessary for exposure if the ligation must be performed inferior to the supraclavicular triangle. Laryngoscope. [19, 20] Its progressive use has displaced most other, more conventional, intraoperative techniques used for providing hemostasis, such as clamping, tying, and electrocauterization. Al Azhar University ; , Al-Azhar Med. 14 or No. Careful handling of the carotid artery and preservation of the adventitia are most important. Accomplish ligation with 1-0 silk suture. J Clin Oncol. See Table IIIE-1 ( PDF) and Cervical Lymphadenectomy- General Considerations protocol of selected N1 neck dissection Serves as a staging procedure and can be used for decision making regarding the need for adjuvant postoperative radiation therapy In selected groups of patients with N+ disease, the use of SND is gaining support. Continuing Education with Television (CETV). The skin incision varies depending on whether the operation is on a single side of the neck or on both sides and whether the lip needs to be split for access to the oral cavity. The transection of the marginal mandibular branch of the facial nerve produces lower lip weakness. [Medline]. Therefore, loss of sensation occurs in multiple areas (eg, neck, posterior occiput, external ear, mandibular region, lateral shoulder, deltoid area, upper pectoral area). Mücke T, Mitchell DA, Wagenpfeil S, Ritschl LM, Wolff KD, Kanatas A. BMC Cancer. The exposure and identification of the carotid-internal jugular axis help in understanding the depth perception in the different planes (arrow 1). The supraomohyoid neck dissection is a selective cervical node dissection that removes the contents of the submentai and submandibular triangles (lymph node level I), the jugulodigastric and jugulo‐omohyoid lymph node groups, and the lymph nodebearing tissues located anterior to the cutaneous branches of the cervical plexus and above the omohyoid muscle (lymph node levels II and III). The anterior belly of the digastric muscle is exposed. A large volume of air rapidly enters the open vein by negative pressure and passes directly into the right atrium, causing a sudden alteration of the central circulation, which leads to tamponade of the heart and even death. Identify the hypoglossal nerve deep into the fascia of the submandibular triangle. Step 1 (Figure 7) The surgeon . Elective management of the neck in oral cavity squamous carcinoma: current concepts supported by prospective studies. Kos M, Engelke W. Advantages of a new technique of neck dissection using an ultrasonic scalpel. Administer antibiotics that cover gram-positive and gram-negative organisms. Watch for the cervical plexus and the phrenic and vagus nerves. Most patients have a nasogastric tube (NGT).

Frequency and therapeutic implications of "skip metastases" in the neck from squamous carcinoma of the oral tongue. Monitor for possible fistula if the oral or upper digestive tract was opened, particularly during postoperative days (PODs) 3 and 4. Generally, the following characteristics of nodal metastasis affect prognosis in the supraomohyoid neck dissection: Extracapsular spread: This condition adversely affects the prognosis. Place the unfixed specimen as it appears in the patient and transfer to the pathology department from the operating room. Elsevier; 2008. Reduction of occult metastatic disease by extension of the supraomohyoid neck dissection to include level IV. 2008 May. 1967 Dec. 76(5):975-87. 1999 Jul. When radiation therapy has been administered, sutures or clips should remain in place for at least 10 PODs. Do the same with the internal jugular vein. Removal of lymph nodes in levels I–IV, with sparing of internal jugular vein, … The Otolaryngology Clinics of North America. Although general opinion holds that selective neck dissection is a good alternative for the N0 neck, other alternatives are available (eg, elective treatment, waiting and observing, surgery, radiation). Background: No clear consensus has been reached on the indication of supraomohyoid neck dissection (SOHND) for clinically positive lymph-node metastasis. When the sensory branches of the cervical plexus are found, the dissection continues in a plane lateral to these nerves. The accessory nerve is encountered in the upper portion of the SCM during the peeling maneuver. Another way to dissect the IJV is to use a vascular forceps with the assistance of scissors, hemostat, or both. 2005. 2014 Aug 6. The plane of the carotid-internal jugular axis is identified anteriorly. The first step was to define radical neck dissection as the standard procedure, considering the remaining procedures as modifications of the standard. J Laryngol Otol. 1990 Oct. 160(4):405-9. Lonneux M, Lawson G, Ide C, Bausart R, Remacle M, Pauwels S. Positron emission tomography with fluorodeoxyglucose for suspected head and neck tumor recurrence in the symptomatic patient. A hematoma usually manifests in the first few postoperative hours. In the supraomohyoid neck dissection, the carotid artery is covered by the SCM muscle. The inferior limit is the superior belly of the omohyoid muscle where it crosses the internal jugular vein. Farber LA, Benard F, Machtay M, Smith RJ, Weber RS, Weinstein GS. When considering the merits of preservation of sublevel IIB, the benefit of preservation of SAN function has to be weighed against potentially reduced oncologic control. Some surgeons also use a floppy, moderately compressive dressing in addition to the suctioning system mentioned above. The following section describes a step-by-step approach for the dissection of neck levels I to V in a sequential fashion. It consists of removal of cervical lymphatic nodes contained in neck levels I, II and III. If a fistula is present, divert it from the carotid area. The … This new approach to neck dissection carried a need for a comprehensive classification inclusive of all types of modifications to the radical operation. Chyle accumulation under the flap can cause redness and swelling of the flap with induration of the surrounding tissues. Chapter 40 Lateral Neck Dissection Technique Carol M. Lewis, Randal S. Weber Please go to expertconsult.com to view related video Lateral Neck Dissection for Differentiated Thyroid Cancer. Elective management of the neck can be accomplished with surgery or radiation therapy. Antonio Riera March, MD, FACS Professor, Department of Otolaryngology-Head and Neck Surgery, University of Puerto Rico School of Medicine In the N+ neck, standardization is lacking; see text for a detailed description of indications and contraindications. Occasionally, hypernatremia, hypokalemia, hypercalcemia, and hypophosphatemia are also associated with neck operations. J Craniomaxillofac Surg.

If you log out, you will be required to enter your username and password the next time you visit. Fourth Edition. If performed incorrectly, in a deeper layer, the dissection runs under the plane of the carotid sheath and IJV. 36(3):425-30. Identify and preserve the superior thyroid artery and the hypoglossal nerve. The supraomohyoid neck dissection is a selective cervical node dissection that removes the contents of the submental and submandibular triangles (lymph node level I), the jugulodigastric and jugulo-omohyoid lymph node groups, and the lymph node-bearing tissues located anterior to the cutaneous branches of the cervical plexus and above the omohyoid muscle (lymph node levels II and III). The carotid sheath (C), the vagus (V), and the accessory nerve (rectangle) are identified. Preserving level IIb lymph nodes in elective supraomohyoid neck dissection for oral cavity squamous cell carcinoma. Supraomohyoid neck dissection is indicated in N0 neck for squamous cell carcinoma (SCC) of oral cavity and oropharynx (include level 4) and N0 neck malignant melanoma where primary site is anterior to ear (include parotidectomy for face and scalp). If the surgery is performed with other procedures that are more complex and prolonged, a Foley catheter … The surgical wound has healed satisfactorily. [Medline].

Skin necrosis, infection, and accumulation of pus adjacent to the carotid wall alert the surgeon to a potential carotid artery rupture. Fourth Edition. Careful handling of the carotid arterial system in the neck with gentle retraction, ligation, and manipulation prevents dislodgment of arteriosclerotic plaques from the internal carotid system. If playback doesn't begin shortly, try restarting your device. As the gland is reflected posteroinferiorly, the facial artery is reencountered and can be ligated. [Medline]. In this manner, the supraomohyoid neck dissection is both diagnostic and therapeutic. 128 (7):751-758. Civantos FJ, Moffat FL, Goodwin WJ. Share.
