Abstrakt:	Objective: The aim of the present study is to examine the operative technique and results of the treatment of trigeminal neuralgia (TN) by percutaneous microcompression of the trigeminal ganglion (Mullan's technique) in 20 consecutive patients over 3 years. Patients and Methods: The average age of the patients was 63 years. There were 8 men and 12 women. The operative technique is similar to Mullan and Lichtor's original description with some modifications. Results: On average it takes 30 minutes to complete the procedure. On 2 occasions the catheter had to be replaced as the balloon burst without clinical repercussions. Detectable changes were noted in systemic blood pressure and cardiac rhythm in 10 cases. On 17 occasions the radiographic appearance of the balloon was pear-shaped and in the remaining cases it was oval or irregular. Follow-up ranged from 6 months to 3 years. All but 1 patient were initially relieved of pain and it was progressively possible to suspend treatment with carbamazepine. The recurrence rate was 25%. Mean time until recurrence was 18 months. There was no relation between pain location and recurrence. Morbidity: some degree of transient cheek discomfort, herpes simplex perioralis, hypesthesia and masseter weakness were the rule. Meningitis in one case. Conclusions: Early results indicate that Mullan's technique provides a reliable, safe, cheap and effective, with low morbidity and no mortality.
