Cryosurgery of headache.

Abstract

The use of cryosurgery applied to the sphenopalatine area (artery and ganglion) plus the superficial temporal and occipital branches of the external carotid artery has proven worthwhile in a majority of patients in whom this procedure has been used since 1968. Experience includes almost 700 procedures in more than 500 patients who have answered to follow-up. The procedure is not a major operation, is repeatable and, until the ideal drug is discovered, offers a better than average change for definite improvement in vascular headache.
