Surgical treatment of trigeminal neuralgia.
Patients who had uncontrolled pain with carbamazepine therapy and those who suffered adversely from its side effects were selected for this safe, simple and repeatable surgery. Pain-free periods were achieved for at least 2 years. Functional difficulty was not experienced in the affected numb areas. When it recurred, pain was less intense and was better controlled with a reduced dosage of carbamazepine. In four cases, after avulsion of the involved nerves, a suitable-sized titanium screw was inserted into the mental and infra-orbital foramina. Obturation of the foramen prevented nerve regeneration, which further prolonged the pain remission period.
