The objective of the study was to compare the results of the patients treated with crystallized phenol treatment (CPT) or simple primary closure (SPC) for pilonidal sinus disease (PSD). For PSD treatment, both SPC and CPT have the advantages of rapid recovery, minimal pain, and short hospital stay. Even though these two techniques can be used interchangeably in uncomplicated cases, there is not enough evidence about which method is superior. A total of 102 patients who underwent CPT (n = 57) and SPC (n = 45) for uncomplicated PSD were included in the study. In all of the cases, data were recorded and compared between CPT and SPC groups, including age, gender, duration of the symptoms, hospital stay, complications, healing time, and recurrence. The mean age was 25.6 years and the male-to-female ratio was 93:9. The SPC and CPT groups were similar in terms of age, gender, duration of symptoms, complications, and healing time. The CPT group did not require hospitalization or anesthetic procedure in addition to local anesthesia, but the SPC group required a median of 1 day (range, 1–3 days) of hospitalization, and 3 patients (6.7%) needed spinal anesthesia. During a median of 27.5 months' follow-up, the recurrence rate in the CPT group (6 patients; 10.5%) was lower than in the SPC group (13 patients; 28.9%). Both hospital stay and recurrence rates were better in the CPT group. Healing time and complication rates were similar in both methods. Based on these results, we suggest that CPT should be preferred to SPC in uncomplicated cases.
