ABSTRACT
OBJECTIVE
The purpose of this study is to review the surgical results of 19 patients with idiopathic trigeminal neuralgia treated by percutaneous ballooning compression(PBC) of trigeminal gasserian ganglion under brief general anesthesia. METHODS: The mean patient age was 63.5 years(range, 27-78). The mean follow-up period was 24 months(range, 1-46). Three patients had already undergone radiofreqnency trigeminal rhizotomy and two patients had previously microvascular decompression. The balloon was inflated by injecting radio-contrast media 0.7-1cc in amount. The mean inflating time is 81 seconds(range, 60-90).
RESULTS
During the procedure, brief intraoperative bradycardia and hypotension were noted in seven cases(36.7%). All patients had immediate relief of pain except 1 case. 18 cases(94.5%) of patients were satisfied or very satisfied with their pain relief. There were immediate, mild to moderate sensory complication of hypesthesia, dysesthesia or paraesthesia in all cases and the immediate motor complication-difficulty of mastication in 3 cases, transient 6th nerve palsy in 2 cases. The immediate motor and sensory complications disappeared or much improved after 3-4 months.
CONCLUSION
It is the simple technique that can be performed effectively in a brief period of general anesthesia. This procedure might be one of attractive methods in the treatment of idiopathic trigeminal neuralgia.
