Voice and Quality-of-Life Outcomes of Diode Laser for Tis-T1a Glottic Cancer.

The aim of this prospective study was to analyze the voice and quality-of-life outcomes of microscopic diode laser surgery (MDLS). The study was conducted on a series of 46 patients with Tis-T1a glottic carcinoma treated with microscopic endolaryngeal diode laser surgery. Patients were asked to complete the Voice Handicap Index and quality-of-life questionnaires of the European Organization for Research and Treatment of Cancer. When comparing the pre- and postoperative scores, there were significant difference on the physical scores (P = .014) of the patients who underwent type III cordectomy and functional (P = .022), emotional (P = .002), and overall scores (P = .005) of the patients who underwent type IV cordectomy, in the direction of better quality of voice after MDLS. The postoperative functional, physical, emotional, and overall scores of groups were significantly increased with the extension of resection.
