Background & Objectives：This study summarized the clinical presentation, treatment and results of the preauricular sinuses, and evaluated the factors contributing to the recurrence after extirpation in Korea.Method：A retrospective study was performed from January 1995 to June 2005 in Uijeongbu St. Mary’s Hospital, The Catholic niversity, Korea. Results：A total of 69 patients (74 ears) were enrolled in this study. Their mean age at the time of surgery was 16.4 years (SD=13.0 years). The right and left side was involved in 30 and 34 ears, respectively. The most common location of the pit was the anterior margin of the ascending limb of the helix (93.2%). The most common surgical indication was the recurrent exacerbations of acute infection (71.6%). The recurrence rate after surgery was 5.4% in this study. Conclusion：Complete removal of the epithelial lining provides a lower recurrence rate. The factor contributing to recurrence after surgery was the use of local anesthesia. The limitation of this study was that the number of recurrent cases was too small to analyze the factors statistically. (J Clinical Otolaryngol 2006;17:49-55)
