Abstract
Objectives Report our experience in the endoscopic treatment of supraglottic cancer with CO2 laser. Show the outcome reached with laser microsurgery in the treatment of supraglottic cancer. Methods From 1990 to 2007, 19 patients with supraglottic cancer underwent CO2 laser microsurgery. Results There were 7 (36.8%) T1, 5 (26.4%) T2, and 7 (36.8%) T3. T1 and T2 supraglottic tumors underwent endoscopic surgery with CO2 laser. T2 stage patients also were submitted to unilateral neck dissection. 2 patients (10.5%) with early supraglottic cancers had recurrence (one local and cervical and another cervical metastasis submitted to external surgery). Supraglottectomy with CO2 laser was performed to analize the preepiglottic space and to allow tumor stage. All T3 supraglottic tumors had pre-epiglottic invasion and underwent external supraglottic laryngectomy with neck dissection. Conclusions Endoscopic treatment for laryngeal cancer is an efficient therapy for early supraglottic cancers and is the best method to evaluate the preepiglottic invasion. This therapy makes local function possible without prejudice to oncological results.
