Multiple Odontogenic Keratocysts in Maxilla and Mandible; A Case Report

Abstract

Otolaryngologists in Japan seem to be unfamiliar with the odontogenic keratocyst, because no report of this disease has appeared. A review of the clinical and histological characteristics of odontogenic keratocysts indicates that they belong to the same category as epidermoid cysts or cholesteatomas in the maxillary sinus.
A 32-year-old man had complained of right cheek swelling since September, 1983, and was referred to our clinic (Nagano Red Cross Hospital) in December, 1983. Radiological examination revealed four cysts accompanied by bone destruction in both maxillas and mandibles. In May and June, 1984, four cysts were totally removed. Histological examination showed that the epithelial lining of each cyst was covered with stratified squamous epithelium accompanied by parakeratosis. A diagnosis of odontogenic keratocyst was made. No recurrence has been evident 4.5 years after treatment.
