Despite a wide variety of surgical techniques to treat chronic pilonidal disease, high rates of recurrence are common. The current study analyzes the outcome of unroofing with limited excision combined with structured postoperative wound care for pilonidal disease. We performed a retrospective review of all patients who were treated with this technique over a seven year period. Ninety-four patients aged 11 to 63 (mean age 26) received this treatment for pilonidal disease. Eighty-nine patients were treated for primary pilonidal disease and five were treated for recurrent disease after procedures such as flaps. There were 66 males (70%) and 28 females (30%). The operation was performed by unroofing the entire pilonidal sinus along with its pits and area of chronic abscess cavity. All granulation tissue was removed and the base of the sinus was completely cauterized. No wide local excisions were performed. The cavity was packed with dry gauze and the dressing was changed twice daily. Patients were seen postoperatively on a weekly basis in clinic. The area was shaved; the cavity was cleaned and often treated with silver nitrate. In the event of premature skin closure starting to form, unroofing was easily performed in the office. The median time to achieve complete healing was 53 days requiring, on average, seven visits. With a mean follow-up of 40 months, there were two recurrences (2.1%) and reoperation for two (2.1%) inappropriately healing wounds. This study demonstrates that unroofing with limited excision and structured postoperative care for pilonidal disease is a safe and effective treatment approach with a very low recurrence and complication rate.
