Background and Objectives：The surgical goals of glottic cancer should not only be to preserve life but also to preserve laryngeal functions such as airway, aspiration prevention, and voice production. Vertical partial laryngectomy preserve laryngeal functions if we carefully select surgical indications. The aim of our study was to evaluate the surgical outcome of vertical partial laryngectomy oncologically and physiologically for the treatment of glottic cancer. Subjects and Method：Forty-one glottic cancer patients were treated with vertical partial laryngectomy at the Department of Otolaryngology-Head and Neck Surgery, Hanyang university hospital from 1993 to 2002. We reviewed the patient charts retrospectively with respect to age, sex, tumor stage, reconstruction, tracheostomy tube decannulation, oral feeding time, postoperative complication, and recurrences. Results：There were six recurrences (14.6%) in the primary site, and recurrence rate was higher in T2 & T3 stage. No patient had recurrence of the cervical lymph nodes. The average decannulation time of tracheostomy tube was 13 postoperative days. The average oral feeding time was 12 postoperative days. There were significant differences in MPT, jitter, shimmer and HNR between the normal control and the cases group (p<0.05). Conclusion：Functional outcome after vertical partial laryngectomy was relatively satisfactory. Vertical partial laryngectomy is a oncologically safe procedure for the treatment of T1 and selected T2 glottic cancer.
