Long-term results of sphenopalatine ganglioneurectomy for facial pain.

Hemifacial pain associated with increased ipsilateral autonomic discharge can be both a diagnostic and therapeutic dilemma. Although frequently treatable with medication, some patients require surgical therapy in the form of sphenopalatine ganglion neurectomy. We report our experience with this procedure in 12 patients with long-term follow-up. Although there is a high incidence of pain recurrence, the pain is usually less severe and can be managed with medications.
