Painful Neuroma Treatment of the Supraorbital Nerve and Forehead Neurotization Using Human Cadaveric Nerve Allograft.

Neuroma pain can be severe, persistent, and treatment-resistant. Forehead and scalp anesthesia is troublesome for patients. Following an iatrogenic ablative injury to the right supraorbital nerve, with subsequent painful neuroma formation, a human cadaveric nerve allograft (AxoGen, Alachua, FL) was used to restore sensation of the right forehead and treat pain. At 1-year follow-up, the patient was pain-free, and protective sensation to the right forehead was recovered with comparable static and dynamic 2-point discrimination between the injured (20 mm, 12 mm respectively) and the normal side (15 mm, 10 mm respectively). This is the first reported case of using a cadaver nerve allograft for successful direct neurotization of the skin and restoration of sensation in the upper part of the face, and for treating painful neuromas. Moreover, a brief review of the available techniques for treating neuromas of the supraorbital and supratrochlear nerves is provided.
