A Randomized Controlled Pilot Study Evaluating Avive+ Soft Tissue Matrix for Prevention of Superficial Radial Nerve Morbidity Following Radial Forearm Free Flap Harvest
A Randomized Controlled Pilot Study Evaluating Avive+ Soft Tissue Matrix for Prevention of Superficial Radial Nerve Morbidity Following Radial Forearm Free Flap Harvest
Radial forearm free flap (RFFF) reconstruction is commonly used for head and neck defects but is associated with donor-site morbidity, including neuropathic pain and sensory disturbance. This randomized controlled pilot study evaluates whether placement of a soft tissue matrix over the superficial radial nerve at the donor site reduces neuropathic pain and improves sensory outcomes compared to standard closure alone.
Radial forearm free flap (RFFF) harvest is associated with significant donor-site morbidity, including neuropathic pain, hypoesthesia, and functional impairment related to superficial radial nerve irritation and postoperative scar formation. Current donor-site management focuses on wound closure and healing but does not directly address nerve protection.
Avive+ Soft Tissue Matrix is a human-derived biologic material designed for soft tissue reinforcement and protection. Its use as a barrier over surgically manipulated nerves is biologically plausible but has not been studied in this clinical context.
This study is a prospective, randomized controlled pilot trial designed to evaluate the feasibility, safety, and preliminary efficacy of Avive+ placement over the superficial radial nerve during RFFF harvest. Subjects will be randomized to standard closure versus Avive+ placement plus standard closure. Outcomes will focus on neuropathic pain, sensory function, and wound complications.
