Background:
Meige's syndrome severely impacts quality of life. Current treatments struggle to balance cost, risk, and effectiveness.
Methods:
Patients with blepharospasm were treated with facial nerves partial radiofrequency ablation guided by CT. Treatment efficacy, complications, and recurrences were evaluated during follow-up.
Results:
116 facial nerves in 58 patients with Meige's syndrome were treated using CT guidance. The average temperature at the end of radiofrequency treatment was 77.93 ± 9.8 °C, and the procedure lasted an average of 30.79 ± 7.69 min. Spasms stopped after treatment, but mild facial paralysis remained. Follow-ups ranging from 12 to 57 months showed that facial paralysis improved in an average of 3.12 ± 0.94 months. Nine patients had unilateral recurrence within 6-13 months, and three had bilateral recurrence at 14, 18, and 22 months.
Conclusions:
Partial radiofrequency ablation of the facial nerve through percutaneous access to the bilateral stylomastoid foramen using CT navigation is an effective, safe, promising treatment for blepharospasm in Meige's syndrome patients.
