Background & Objectives : Supraglottic partial laryngectomy is oncologically sound surgical procedure for selected cases of laryngeal cancer which maintains physiologic speech and swallowing without permanent tracheostoma. The purpose of this study is to evaluate the oncologic and functional results of supraglottic partial laryngectomy and neck dissection for supraglottic cancer.
Materials & Methods : Between 1991-2005, Twenty-three supraglottic cancer patients, underwent supraglottic partial laryngectomy, were studied retrospectively. There were 5 patients with cT1, 14 with cT2, 4 with cT3 and 11 patients with cN0, 1 with cN1, 10 with cN2, 1 with cN3. All patients underwent neck dissection and postoperative radiotherapy was added to twenty patients. They were reviewed with respect to primary subsites, extended subsites, treatment result, survival rate, factors affecting the prognosis, postoperative complication, time of decannulation and oral diet, and postoperative voice.
Results : Among eleven patients with clinically negative node, six patients had pathologically positive nodes. So occult metastasis was 54.5%. Two patients recurred at cervical lymph node and one had distant metastasis to lung. Local and regional control were 100% and 91.3%. The overall 3-year and 5-year survival rate were 84%, 78%, respectively. Nineteen cases were squamous cell carcinomas and four were basaloid squamous cell carcinomas. Basaloid subtype was significantly affected to survival. Decannulation and oral feeding were possible in 100%.
Conclusion : Supraglottic partial laryngectomy is oncologically safe and functionally good procedure in supraglottic cancers. Elective neck dissection is beneficial in management of occult cervical metastasis.
