Surgical treatment of facial nerve palsy:an analysis of the operation efficacy in 29 patients

Objective To evaluate the effect of surgical treatment in facial nerve paralysis.Methods Clinical data of 29 cases in facial nerve paralysis were retrospectively analyzed.All of the 29 cases of facial paralysis,18 cases is the suppurative otitis media,9 cases is the temporal bone fracture,2 cases is the neoplasms of the temporal bone.The 29 cases of facial nerve paralysis were surgical treatment.8 cases by vertical segment or horizontal segment of facial nerve decompression,19 cases by the stylomastoid foramen to the geniculate ganglion of facial nerve decompression,2 cases by the itratemporal course of facial nerve decompression.1 case was underwent end-to-end anastomosis,2 cases of the greater auricular or the sural nerve graft for repairing facial nerve defect.All data were analyzed with Rank sum test.Results Makes a follow-up visit for 6～18 months,the facial nerve function(House-Brackman grading system)before the technique Ⅱ 6.9%,Ⅲ17.2%,Ⅳ34.5%,Ⅴ 31.0%,Ⅵ 10.3%,after the technique,restores Ⅰ 6.9%,Ⅱ27.6%,Ⅲ27.6%,Ⅳ 24.1%,Ⅴ 13.8%,statistics analysis facial nerve function restoreS has the significance difference(P＜0.005).Conclusions The facial nerve decompression and the nerve graft are useful method to treat facial paralysis.Surgical treatment of facial paralysis is satisfied in the suppurative otitis media and the temporal bone fracture.
