Objective: The aim of this study was to evaluate outcomes and complication rates
associated with percutaneous trigeminal ganglion compression (PTGC), followed up
for at least 5 years.
Methods: The authors report on 100 cases of trigeminal neuralgia treated by
percutaneous trigeminal ganglion compression from June 2000 to June 2001. The
operation was performed under general anesthesia with endotracheal intubation.
Meckel’s cave was cannulated with No.4 Fogarty catheter and the balloon was
inflated for 70 to 90 seconds.
Results: A 5-year follow-up study was completed for all the 100 patients. Fifty-one
patients (51%) were 65 years of age or above. Ninety-four patients (94%) were
immediately relieved of their neuralgia after the procedure. Three patients had
postoperative cheek hematoma. Thirty-three patients developed herpes simplex
perioralis after the operation. Two patients had transient 6th nerve palsy, which
subsided within 3 months. There were no major surgical complications, no
anesthetic complications and no death. No pain recurred within 3 months. Thirteen
patients (13.8%) had recurrent symptoms within 2 years. Fifteen patients (16%) had
recurrent symptoms within 3 years. In all, 27 patients (28.7%) had recurrent
symptoms over the entire 5-year study period.
Conclusions: PTGC is a technically simple, relatively noninvasive procedure that
can be carried out under brief general anesthesia. The patients can tolerate well the
treatment. The procedure, at present, is the first choice for those trigeminal
neuralgia patients who are poor medical risks, who are above the age of 65, and who
are unwilling to accept the risk of a posterior fossa craniectomy. |
