Dentoalveolar fistulas of the cervical region

The otolaryngologist is very familiar with inflammatory lesions occurring in the head and neck. The chronic draining fistula is somewhat less common, and its origin may be obscure. A case presentation illustrates some of the typical problems of a fistula in the submandibular triangle which proved to be of dental origin. Knowledge of the spread of periapical infection helps to understand the development and location of cutaneous, dentoalveolar fistulas. Recognition of the source of the fistula is essential as treatment must be directed primarily to the underlying dental infection.
