[Article in Chinese] Hua N, Wei L, Jiang T, Guo Y, Wang M, Wang Z. OBJECTIVE: To investigate the pathology characteristics of congenital preauricular fistula with infection, in order to reduce the recurrence rate after surgery and improve operative technique. A pit or dimple in front of the ear of a newborn is a common finding; rarely, such a dimple may get infected, which will be manifested with redness and swelling and will require medical attention. Preauricular fistula(PAFC) MedGen UID: 154283. Objective: To determine the histologic relationship and distance between excised preauricular epithelial sinus tract and the adjacent auricular cartilage (sinocartilaginous distance) in a series of patients. The excision of preauricular sinuses is a common surgical procedure. Recurrences are frequent and can be technically challenging.

Background: Preauricular fistula is a congenital malformation of the six auditory hillocks during the development of auricle, when an imperfect fusion of the first arch tuberculum to other tuberculums occurred and generated a tract. It is characterized by a nodule or a dent located adjacent to the external ear.
