Surgical Treatment of Axillary Hidradenitis Suppurativa Using Preliminary Defect Closure and Two Sliding Island Triangular Skin-Subcutaneous Flaps from the Arm and Chest.

: Surgical excision of axillary hidradenitis suppurativa (HS) often results in challenging defects. While flap techniques offer durable coverage, they are typically invasive. We present a modified method combining peripheral defect reduction with two sliding triangular island flaps from the arm and chest, designed to optimize healing with minimal invasiveness. Twelve patients (Hurley II-III) underwent excision and dual V-Y advancement flap reconstruction. Flaps were mobilized without perforator dissection. Outcomes were assessed using patient and surgeon Likert-scale ratings at one and six months. Good healing was achieved in 91.7% of cases. Both patient acceptance and cosmetic outcomes were favorable (83.3%). No major complications were noted; one recurrence (8.3%) occurred at six months. The described technique offers a safe, effective, and cosmetically favorable option for medium-sized axillary HS defects. It provides a less invasive alternative to conventional flaps, with high healing rates and patient acceptance.
