Interdisciplinary treatment of post-concussion and post-traumatic headaches.

Abstract

Chronic headaches following concussion are debilitating and difficult to treat. Commonly employed initial therapeutic modalities include pharmacologic, physical, and psychological interventions. Despite these efforts, a subset of patients with chronic pain remains. Peripheral nerve surgery has never before been reported as an effective treatment for the management of post-concussion headaches. In this study, we report on our early outcomes following peripheral nerve surgery for this novel indication. A retrospective review of 28 consecutive patients with post-concussion headaches who underwent occipital nerve surgery was performed. Preoperative and postoperative headache pain was evaluated on visual analog scale (VAS) in 24 patients with at least 6 months follow-up. The average VAS headache pain reduced from 6.4 preoperatively, to 1.4 (P < 0.0001). Twenty-one patients (88%) had a successful outcome of at least a 50% reduction in their VAS following peripheral nerve surgery. Additionally, twelve patients (50%) were pain free at time of final follow-up. There were no surgical complications. Early results indicate peripheral nerve surgery is a safe and effective new therapy for post-concussion headaches in the properly selected patients, whose chronic pain persists despite initial treatments by a neurologist, specialized in headache management. Future studies should focus on larger patient populations, and examine the long-term durability of outcome. In the meantime, an interdisciplinary approach involving neurologists and a peripheral nerve surgeon is suggested for the care of patients with refractory chronic post-concussion occipital neuralgia and other post-traumatic chronic headaches.
