Treatment options of pilonidal sinus, which has high recurrence rates, is still controversial. In this study, we aimed to analyze for possible factors affecting recurrence. Forty-one patients with recurrent pilonidal sinus were included in this study. Of them, 33 were male and 9 were female (mean age, 24.9 years; age range, 16-42). Factors (i.e., risk factors) were detected in 32 patients. Excision-secondary healing and lay open was performed on 30 of the patients admitted with recurrence. Excision and flap closure was applied on 11 patients. Our recurrence rate was 9.7%. The recurrence rate of our study is compatible with the literature. Comparative studies are needed to determine the appropriate method to decrease recurrence rate.
