The purpose of this report is to present the results of clinical observation upon 21 surgical cases with tic douloureux (female 13, male 8) during the period from January, 1960 to August, 1972 at the Department of Neurosurgery, Seoul National University Hospital, Seoul, Korea. The average age at onset was 48 years of age ranging from 22 to 66 years. The average duration from onset to operation was 5 years. The frequency of involvement was the highest in the maxillary division, next was maxillary and mandibular division, and none in the ophthalmic division. Whole division was involved in one case. Right-sided involvement predominated by a ratio of 2 to 1 and bilateral involvement was found in only one case. Extraction of innocent teeth, ungratifying operation upon paranasal sinus had been carried out in 11 cases as consequence of misdiagnosis. Alcohol injection of peripheral branches of trigeminal nerve and medical treatment produced short-lived or none-effectiveness. Trauma to ipsilateral mandible and epidermoid cyst at cerebellopontine angle seemed to be the cause of tic doulourex in 2 cases, respectively. Major complications observed in Frazier's method group, were paresthesia, facial nerve palsy, partial paralysis of motor root, and recurrence of neuralgia. All of the peripheral nerve avulsion group developed recurrence of pin within three years. Mild decrease of cornea reflex was noted in two cases of Dandy's method group. Posterior fossa operation stands in superiority, when it is considered that some pathologic lesions are frequently found in the posterior fossa, that motor root is less frequently injured, and that the light touch is so fairly preserved in all three divisions that the least damage to the cornea is expected.
