2. described two patients with hemifacial spasm and ipsilateral trigeminal neuralgia. His first patient had clear-cut cerebellar signs and was therefore atypical, and his second patient was not subjected to angiography. Both patients were excluded from the series. Two other patients-one with a cirsoid aneurysm and one with a cholesteatoma-were excluded because the only documentation of their illness was passing reference in a paper by;Maurice-Williams,1973
3. The facial pain of painful tic convulsif was usually relieved by diphenylhydantoin, carbamazepine, or a combination of the two. Neither of these medications relieved the hemifacial spasm, however. Ethanol injection of the gasserian ganglion temporarily relieved some patients of their trigeminal neuralgia but had no effect on their hemifacial spasm. Successful treatment of hemifacial spasm in painful tic convulsif-that is, alleviation of spasm with preservation of seventh nerve function-has been achieved only by Gardner (1968), whose operation involves saline neurolysis of the facial nerve within the posterior fossa
