Trigeminal neuralgia (tic douloureux) is a painful paroxysm of one of the branches (usually, the second or third division) of the trigeminal nerve, and the neuralgia may slated to disseminated (multiple) sclerosis, to anoxia from vasospasm, or to ischemia from other casuses in the region of the gasserian ganglion or sensory root.
Trigeminal neuralgia has been treated by drugs, nerve injections, surgery, and acupuncture. The drugs used in the past, such as as diphenylhydantoin(Dilantin), have largely ba2n supplanted by carbamazepine (Tegretol), and it has proven remarkably effective in controlling the pain of trigeminal neuralgia. Nerve blocks of the trigeminal ganglion that
use alcohol, pbenol, or hot water have also been reported to bring relief.
Trigeminal tractotomy may or may not relieve the condition. However, surgical division of the sensory root in the medulla oblongata gives permanent relief.
Other forms of treatment include trigeminal decompression and percutaneous electrocoagulation to cauterize the trigeminal nerve. Peripheral neurectomy is an effective treatment of trigeminal neuralgia because it interrupts the flow of a significant number of afferent impulses to the central trigeminal apparatus. We had performed peripheral neureatomy in a case. Th? pain free period obtained by peripheral neurectomy and the drugs (carbamazepine) in patient with trigeminal neuralgia and orofacial pain is signifi cant. The purpose isto report our observatoni on the case report and the effectiveness of p--ripheral neurectomy of buccal nerve.
