Objective:
This prospective study aimed to evaluate the results of percutaneous trigeminal ganglion balloon compression (BC) in patients with various types of trigeminal neuralgia (TN) and autonomic cephalalgia.
Methods:
Twenty-five consecutive patients underwent BC and were followed up for 27-60 months. They were divided into 2 groups: group A (n=18) patients with idiopathic TN and group B (n=7) patients with secondary TN (n=5) and trigeminal autonomic cephalalgia (TAC) (n=2).
Results:
Postoperatively, 15 patients in group A experienced pain relief, one required medication and 2 had no response; in group B, 6 were free of pain, including the 2 patients with TAC, and one required medication. Complications in both groups were either functionally trivial or infrequent. None of the patients developed keratitis or anesthesia dolorosa. Pain recurrence occurred early (<6 months) in one patient from group B, and late in 2 patients from group A.
Conclusion:
Balloon compression is a minimally invasive procedure that seems to be comparably successful for idiopathic and secondary TN, as well as TAC. However, further studies are deemed necessary to establish it as the first-line treatment in medically resistant trigeminal pain.
