A Clinical Study of Cases with Vocal Fold Cyst

Abstract

OBJECTIVES: During the past five years 108 patients with vocal fold cysts were examined and treated at the Tokyo Voice Center. In this presentation the clinical records of these 108 patients were studied statistically, especially to compare among different histological types. MATERIALS AND METHODS: The study involved analysis of 108 patients (53 males and 55 females). In all patients, otolaryngological, phoniatric and videostroboscopic examinations were completed. The clinical records of these patients were statistically studied with respect to distribution by age, sex, smoking, and professional voice usage, especially comparing among different histological types. Subsequently these statistical differences were compared with differences between vocal fold nodules and vocal fold polyps. RESULTS AND CONCLUSIONS: 49% of the cases were professional voice users and 15% were non-professional cases who had episodes of vocal abuse. There were significant differences between cases of epidermoid cyst and retention cyst with respect to distribution by age, sex, professional voice usage, and endoscopy findings, just as there were significant differences between vocal fold nodules and vocal fold polyps.
