Effect analysis of facial nerve decompression surgery in the treatment of Bells palsy and Hunt syndrome
Objective:To summarize and analyze the effect of facial nerve decompression surgery for the treat-ment of Bell's palsy and Hunt syndrome.Methods:The clinical data of 65 patients with facial nerve palsy who un-derwent facial nerve decompression in our center from October 2015 to October 2022 were retrospectively ana-lyzed,including 54 patients with Bell's palsy and 11 patients with Hunter syndrome.The degree of facial paralysis(HB grade)was evaluated before surgery,and ENoG,pure tone audiometry,temporal bone CT and other exami-nations were completed.All patients had facial palsy with HB grade V or above after conservative treatment for at least 1 month,and ENoG decreased by more than 90％.All patients underwent facial nerve decompression sur-gery through the transmastoid approach within 3 months after onset of symptoms.The recovery effect of facial nerve function after surgery in patients with Bell's palsy and Hunter syndrome was summarized and analyzed.In addition,15 cases in group A(operated within 30-60 days after onset)and 50 cases in group B(operated within 61-90 days after onset)were grouped according to the course of the disease(the interval between onset of symp-toms and surgery)to explore the effect of surgical timing on postoperative effect.Results:There was no signifi-cant difference between the two groups of patients with Chi-square test(P=0.54)in 42 patients(77.8％,42/54)with Bell's palsy and 7 patients(63.6％,7/11)in patients with Hunter syndrome who recovered to grade Ⅰ-Ⅱ.According to the course of the disease,10 cases(66.7％,10/15)in group A recovered to grade Ⅰ-Ⅱ after surger-y.In group B,39 patients(78.0％,39/50)recovered to grade Ⅰ-Ⅱ after surgery,and there was no statistically significant difference between the two groups by Chi-square test(P=0.58).Conclusion:Patients with Bell's palsy and Hunter syndrome can achieve good results after facial nerve decompression within 3 months of onset,and there is no significant difference in the surgical effect between the two types of patients.
