Analysis Of Risk Factors Associated With Facial Nerve And Auditory Nerve Complications Treated By Microvascular Decompression

Objective: To summarize the clinical efficacy of microvascular decompression for hemifacial spasm and related risk factors for postoperative facial nerve complications.Method: A total of 92 patients with hemifacial spasm who underwent microvascular decompression at the Department of Neurosurgery at the First Affiliated Hospital of Guangxi Medical University from January2012 to December 2016 were included.The patient’s sex,age,duration of disease,preoperative treatment,and vascular responsibility were collected.Whether or not there was any trace of auditory nerves in the operation,whether cotton pads were used,and whether postoperative complications were used for retrospective analysis of the relationship between various factors and postoperative complications and related risk factors for major complications Perform statistical analysis.Results: In this group of 92 patients,6-18 months follow-up visit,70 cases were cured,19 cases were remission,and 3 cases were ineffective.Among them,2 cases had postoperative recurrence,10 cases had hearingimpairment,11 cases had facial paralysis,hearing impairment and facial paralysis.Coexistence in 2 cases.Statistical analysis of various risk factors by univariate revealed that there was a significant correlation between operative time and intraoperative facial nerve pressure traces and postoperative complications(P<0.05).Multivariate logistic regression analysis revealed that the operative time was too long and the facial nerve pressure track was found to be an independent risk factor for facial nerve complications after microvascular decompression(P<0.05).Conclusion: Microvascular decompression was effective in the treatment of hemifacial spasm;postoperative facial paralysis and hearing impairment were associated with prolonged surgery and the presence of facial nerve pressure traces during surgery.
