Epithelial hyperplasia of the larynx. A 10-year review of 88 patients.

A retrospective review of 88 patients with epithelial hyperplasia of the larynx seen at the Department of Otolaryngology Kurume University during the 10-year period from 1971 to 1980 was completed. The results are summarized as follows: 1) The incidence was much higher in males (78 patients) than in females (10 patients). 2) The average age was 56.8 years. 3) The lesion was located on the vocal fold in 84 cases, the ventricular fold in 3, and both vocal and ventricular folds in 1. 4) Fifty-three patients underwent surgical treatments in our hospital. Three of them developed recurrence and 6 developed carcinoma. 5) On histological re-examination, the lesions were classified into three types: simple hyperplasia (Type I), dysplasia (Type II) and carcinoma (Type III). No relationship was found between the macroscopic appearance and the histological type.
