Single stage excision of preauricular sinus.
A total of 44 patients with preauricular sinus underwent one-stage surgical treatment. There were 32 unilateral and 12 bilateral cases giving a total of 56 sinuses. Of these 16 were infected at the time of presentation. Based on the observation that preauricular sinus represents the duct of a preauricular gland which is closely adherent to the fibrocartilage of the ear, the authors propose a method for the complete cure of this lesion by excising the whole gland and duct together. This technique was used in all cases including 16 patients with infected sinuses. There were three recurrences, two of which were due to incomplete excision of the gland. The third case was found to have a fistula leading to an atretic external auditory canal. All other patients have shown no evidence of recurrence on follow up of six months or longer. Our experience has shown that preauricular sinus can be effectively treated at any stage by a simple surgical technique based on a clear understanding of the underlying anatomy of the lesion.
