Objective: The objective of this study was to analyze the clinical features of preauricular sinus and the recurrence rate of supra-auricular approach. Materials and Methods: A total of 87 patients (96 ears) treated for preauricular sinus at the Department of Otolaryngology-Head and Neck Surgery, Pyongyang Medical College Hospital, Kim Il Sung University, between January 2007 and December 2016 were enrolled in this study. Results: The prevalence of preauricular sinus was more common in teenage group (55.2%). Preauricular sinus occurred more frequently in male (1.4 times). The most common type of preauricular sinus was marginal helicine type with 86.5%. The recurrence rate with supra-auricular approach was found to be 3.3% whereas simple sinusectomy was 17.1%. Conclusion: The most common type in the preauricular sinus was marginal helicine type and supra-auricular approach was a reliable technique which had significantly less recurrence rate.
