Abstract:
Objective To explore the clinical application value of CT-guided facial nerve radiofrequency thermocoagulation therapy for hemifacial spasm(HFS).Methods A total of 24 patients with HFS,who were admitted to the Department of Intervention and Pain of the First Affiliated Hospital of Anhui University of Traditional Chinese Medicine of China from July 2017 to June 2024 to receive CT-guided facial nerve radiofrequency thermocoagulation therapy,were enrolled in this study.The preoperative and the postoperative one-day,one-week,one-month,and 3-month HFS scores were used to evaluate the therapeutic effect.The postoperative one-day facial paralysis score was used to assess the degree of facial paralysis.Results Successful intraoperative induction of facial nerve motor stimulation symptoms was achieved in all patients.The minimum voltage for inducing facial muscle twitching through sport stimulation was(0.38±0.12)voltage,and the final radiofrequency temperature was(59.04±7.00)℃.The preoperative and the postoperative one-day,one-week,one-month,and 3-month HFS scores were(6.83±1.09)points,(0.71±0.75)points,(0.50±0.72)points,(0.38±1.06)points,and(0.38±1.28)points respectively.All the postoperative one-day,one-week,one-month,and 3-month HFS scores were significantly lower than the preoperative HFS score,the differences were statistically significant(all P<0.05).The symptoms of HFS were obviously improved in all patients.The postoperative one-day facial paralysis score was(2.67±1.13)points.After treatment,all 24 patients developed mild facial paralysis symptoms.Conclusion In treating HFS,CT-guided facial nerve radiofrequency thermocoagulation can effectively alleviate the spasm symptoms,therefore,it is an effective method for HFS.The complication of facial paralysis is mild,and it can recover spontaneously.In clinical practice this therapy can be recommended to HFS patients.
