Clinical analysis of particular congenital preauricular fistula of 3 cases

Objective To improve the diagnosis and treatment of particular congenital preauricular fistula. Methods A retrospective analysis was made on the clinical data of 3 cases. Results One case, combined with cholesteatoma of middle ear, was resected surgically at the same time; one case of hidden orificium fistulae was completely removed；One case in which the fistula arose from the foot of the helix to the deep external auditory canal and the surface of mastoid process, was completely removed by dual-incision operation. Conclusion Preoperative CT scanning of temporal bone is required for congenital preauricular fistula accompanied with hearing loss. Recurrence depends on whether the fistula, infected auricular cartilage, granulation and scar tissue are thoroughly removed during the operation.
