title: Congenital fistulas of the lower lip. Radiographic evaluation.
abstract: Congenital fistula of the lower lip was observed in 3 members of a family. There was no evidence of associated congenital malformations. In the father, we performed fistulography with radiopaque substance, showing that the fistular tract extended beyond the orbicularis oris muscle, a feature with no previous report in the literature.
