Scalp salvage with acellular dermal matrix assistance for recurrent exposure of deep brain stimulation hardware: a...

Recurrent scalp compromise following deep brain stimulation (DBS) implantation remains a challenging reconstructive problem, particularly in patients with chronic infection and repeated revision procedures. We present an acellular dermal matrix (ADM)-assisted salvage strategy using rotational scalp flap coverage with adjunctive calvarial recession for preservation of exposed DBS hardware. After debridement and subperiosteal flap elevation, ADM was applied over the exposed hardware as a biologic reinforcement layer prior to tension-free closure. Adjunctive calvarial recession was performed to reduce hardware prominence. Postoperative computed tomography demonstrated decreased hardware projection, and stable wound healing without recurrent dehiscence or infection was maintained during follow-up. This combined approach may represent an effective salvage option for recurrent DBS scalp compromise while preserving functional neuromodulation hardware.
