Neurolysis of the Greater Occipital Nerve in Cervicogenic Headache. A Follow Up Study

Authors


Abstract

SYNOPSIS

Entrapment of the greater occipital nerve (GON) in its peripheral course has been thought to be of possible pathogenic significance in cervicogenic headache. We have performed a “liberation” operation (“neurolysis”) of the nerve in the nuchalmusculature, with special attention to the trapezius insertion, and the follow-up results in 50 patients are presented. Theimmediate effect of the operation was quite good, but the pain gradually recurred in the majority (46/50) of the patients.Eventually, all operated patients will probably have recurrence of pain episodes. Nevertheless, most patients claim that theoverall disability is less after the operation, and 40% actually want to undergo a new, identical procedure. The justification for doing a second “liberation” operation is clearly less than for a first operation. In our opinion, this operation should not be performed in patients with cervicogenic headache in general. The present study shows that other therapeutic approache sshould be searched for in cervicogenic headache.
