Extended Endoscopic Posterior Nasal Neurectomy.

A surgical technique for extended endoscopic posterior nasal neurectomy (EPNN) is described, which includes transection of both posterior nasal and posterolateral nasal nerves to treat medically refractory chronic rhinitis. This approach targets a broader range of autonomic and sensory fibers than a traditional EPNN. A case example demonstrates complete symptom resolution at 6-month follow-up.
