title: [A rare case of a preauricular fistula].
abstract: A female patient with a preotic fistula caused by a defect in the development of the first branchial arch is described. Repeated surgeries for lateral fistula of the neck brought no success. The pathogenesis of the defect and difficulties in its diagnosis are discussed; the authors claim that fistulography with contrast agents may be effective. Histologic verification is needed in all the cases.
