Efficacy of Minimally Invasive Crystallized Phenol Application in the Treatment of Pilonidal Sinus in Children

Abstract

Background/Aims: Pilonidal sinus treatment involves surgical excision or flap reconstruction; however, the disease has a high recurrence risk. We determined the outcomes of a modified local application of crystallized phenol. Methods: In the outpatient clinic, the pilonidal sinus orifices were connected by an incision under local anesthesia. The hair in the sinus was removed. Then, crystallized phenol was applied. The incision was not sutured. Daily dressings and baths were recommended. Results: Crystallized phenol was applied to 50 patients with pilonidal sinus disease (median age = 15 years). During the follow-up, no bleeding or pain was reported. Recurrence was not found in the follow-ups (one year to three years). Conclusions: Surgery has disadvantages such as long-term hospitalization, recurrence risk, and high cost. Crystallized phenol does not have any of the aforementioned disadvantages. The modified method, in which we incised and applied crystallized phenol to all sinus tracts, might have also reduced the recurrence.
