Minimally Invasive Trigeminal Ablation: Long Buccal Nerve

To describe a technique of minimally invasive trigeminal nerve ablation of the long buccal nerve that was performed at a tertiary care academic medical center.

This case describes a 44-year-old woman with refractory left long buccal nerve neuropathy following a dental procedure. After failing medical management, she was taken for nerve exploration, which revealed no nerve discontinuity or neuroma formation. She was therefore counseled regarding the risks and possible benefits of a novel minimally invasive trigeminal nerve thermoablation of the long buccal nerve technique.

Postoperatively, the patient experienced mild anesthesia along the long buccal nerve division and no longer experiences any allodynia or hypersensitivity. Additionally, she no longer requires any additional medical therapy or interventions.

Minimally invasive trigeminal nerve ablation of the long buccal nerve may be effective surgical intervention in treating refractory neuropathic pain in cases of no structural nerve defects. However, long-term well-designed studies are required to fully define its role.
