Abstract
Uncontrolled cervical metastasis is the most common source of failure in the surgical treatment of supraglottic carcinoma. This study was designed to determine the value of supraomohyoid neck dissection in patients undergoing supraglottic laryngectomy. The rationale for considering the role of supraomohyoid neck dissection is that such a dissection encompasses the subdigastric and midjugular nodes which are the first echelon of lymphatic drainage of the supraglottic larynx. Thirty-eight patients with a diagnosis of epidermoid carcinoma of the supraglottis were treated by subtotal supraglottic laryngectomy (SSL). Ten patients underwent SSL with no neck dissection, 16 patients underwent SSL with supraomohyoid neck dissection (SOHD)--9 unilateral and 7 bilateral, and 12 patients underwent SSL with radical neck dissection (RND). The 3 groups had comparable T classifications. All of the SSL and SSL with SOHD patients were classified as N0. Of the 12 patients treated with SSL and RND, 4 were classified as N0, 4 as N1, 3 as N2, and 1 as N3. The patients were studied to determine the incidence and pattern of subsequent neck disease, survival, complications, and length of hospitalization. The data indicates that supraomohyoid neck dissection offers little benefit as an adjunct to supraglottic laryngectomy.
