Abstract

The aim of this study is to document the clinicopathologic features of teratoid cyst of the floor of the mouth in 20 Chinese patients, who were treated in Wuhan University. The 20 teratoid cysts were analyzed. All cases were confirmed by pathology. English literature was also reviewed. Our investigations showed that both sexes were equal to have these cysts. The age at diagnosis ranged from 25 days to 34 years, and the greatest frequency was within the first decade. It was found that the congenital cysts were most commonly diagnosed in the midline. All cases were treated by cystectomy, using 1 of the 2 approaches: extraoral or intraoral. Whenever, combined approaches were used in 2 cases. In all, 16 patients were followed-up, and 2 patients had recurrences. The intraoral approach was also effective for the treatment of large lesions and led to very good cosmetic and functional results.
