Deroofing: A tissue-saving surgical technique for the treatment of mild to moderate hidradenitis suppurativa lesions

Background: Hidradenitis suppurativa (HS) is a chronic inflammatory skin disease, often refractory to treatment. Patients with HS and dermatologists are in need of an effective, fast surgical intervention technique. Deroofing is a tissue-saving technique, whereby the "roof" of an abscess, cyst, or sinus tract is electrosurgically removed. The use of a probe is mandatory to explore the full extent of a lesion. Objective: We sought to evaluate the efficacy and patient satisfaction of the deroofing technique for recurrent Hurley I (mild) or II (moderate) graded HS lesions at fixed locations. Methods: An open study consisted of 88 deroofed lesions in 44 consecutive patients with HS, treated by a single clinician with a follow-up time of up to 5 years. Results: Fifteen of 88 (17%) treated lesions showed a recurrence after a median of 4.6 months. In all, 73 treated lesions (83%) did not show a recurrence after a median follow-up of 34 months. The median patient satisfaction with the procedure rated 8 on a scale from 0 to 10. Of the treated patients, 90% would recommend the deroofing technique to other patients with HS. One side effect occurred in the form of postoperative bleeding. Limitations: Some patients were lost to follow-up. Conclusions: The deroofing technique is an effective, simple, minimally invasive, tissue-saving surgical intervention for the treatment of mild to moderate HS lesions at fixed locations and it is suitable as an office procedure.
