• Background We proposed a modified type III cordectomy for the treatment of early glottic cancer that removed the upper part of the vocalis muscle to improve glottic closure and voice outcomes. Methods Twenty‐two patients with early glottic cancer underwent type III cordectomy, including 9 classical (proposed by European Laryngological Society) and 13 modified resections. Multidimensional voice evaluations were performed. Results Voice parameters including GRBAS (overall grade [G], roughness of the voice [R], breathiness [B], asthenicity [A], and strain [S]), jitter, shimmer, noise‐to‐harmonic ratio, maximum phonation time, voice handicap index‐functional, physical, and total scores were better in modified resection. Eleven patients (85%) had complete glottic closure in modified resection and 3 (33%) in classical resection (p = .026). Only 2 patients had tumor recurrence, 1 (8%) in the modified resection and 1 (11%) in the classical resection group (p = 1.000). Conclusions Modified type III cordectomy proved to be an oncologically safe method. The voice outcomes were better than those in patients who underwent classical type III cordectomy. © 2011 Wiley Periodicals, Inc. Head Neck, 2011
