The buccal belt: a buccal mucosal graft sub-coronal resurfacing for recurrent penile adhesions in patients with lichen sclerosus.

Abstract

Penile adhesions may cause pain, bleeding, disfigurement and distress. In the setting of lichen sclerosus (LS), they often recur but current treatment options are limited. We present a novel surgical technique for treatment of recurrent penile adhesions using sub-coronal buccal mucosal graft (BMG) resurfacing. A retrospective, international multi-institutional study was conducted to include patients with refractory penile adhesions who were treated with this technique. Patients with > 12-month follow-up were included in analysis. The procedure involved circumferential excision of the diseased skin and replacement with a BMG. The primary outcomes were recurrence and surgical complications. Secondary outcomes were patient-reported outcome measures (PROMs) including Sexual Health Inventory for Men (SHIM) questionnaire and Global Response Assessment (GRA) questionnaire measuring functional and esthetic outcomes. Twenty-five men underwent the procedure across six institutions between 3/2014 and 11/2019. Twenty-one men met inclusion criteria. Mean operative time and hospital stay for sub-coronal resurfacing were 40min (25-50) and 0.76days (1-2), respectively. At the mean follow-up of 18months (12-61), no patients developed recurrence. All patients who presented with pain and postcoital bleeding saw improvement on follow-up (18/18). There was a significant improvement in SHIM scores after the operation (14.4 pre-op, 17.0 post-op; p = 0.003). Overall improvement of symptoms was reported by all patients: 57% GRA + 3; 29% GRA + 2; 14% GRA + 1. Baseline penile sensation was preserved in 17/21 (81%) patients. Recurrent penile adhesions in the setting of LS are notoriously difficult to treat. A sub-coronal BMG resurfacing is feasible. This initial patient cohort demonstrated no recurrence and overall high satisfaction.
