An Investigation Of Facial Spasm After Microvascular Decompression Surgery

Objective After several decades of development,microvascular decompression(MVD)treatment of hemifacial spasm(HFS)has become more mature and its therapeutic effect is remarkable.However,there are still many complications of the operation,of which facial paralysis is one of the most common postoperative complications,and the incidence of facial paralysis is different in different neurosurgical centers,which greatly limits the further promotion of the operation.The application brings great psychological pressure to clinicians and patients.Therefore,investigating the outcome of facial paralysis after microvascular decompression of hemifacial spasm,factors influencing the recovery of facial paralysis,and response measures can improve the surgical procedure,promote the development of MVD,and reduce the risk of posterior fistulas after facial spasm surgery.Theoretical and evidence support.Methods The patients with hemifacial spasm were treated with microvascular decompression and the patients were followed up for 5 to 18 months.The facial nerve function of patients with facial paralysis was closely followed and recorded.Perform statistical analysis,retrospectively analyze the outcomes of facial paralysis and factors that may affect the recovery of facial paralysis and response measures.Results Among the 128 patients undergoing surgery,facial paralysis occurred in 30 patients.After 18 months of follow-up,facial nerve function recovered to varying degrees in most patients.The duration of facial paralysis ranged from 1 to 18 months(mean,8.3 months).At the end of follow-up,House A total of 7 patients(5.47%)were treated with-Brackmann III(H-BⅢ)and above.Statistical analysis showed that the duration of preoperative and postoperative facial paralysis occurred in the course of more than 4 years,the difference was statistically significant(P <0.05);bivariate Logistic regression analysis showed that: hemifacial spasm duration(OR=0.404,95% CI: 0.175-0.934;P=0.034)was associated with the occurrence of facial paralysis.The time of postoperative facial paralysis,the initial level of facial paralysis and the final duration of facial paralysis were statistically significant(P <0.05).A further multiple linear regression analysis of both showed that the time of facial paralysis had a statistically significant effect on the duration of facial paralysis(P=0.020),and the influence of facial paralysis on the duration of facial paralysis was not statistically significant(P=0.070).Conclusions The incidence of facial paralysis after hemifacial microvascular decompression is higher,but the prognosis is good.The longer the duration of hemifacial spasm,the greater the likelihood of facial paralysis after surgery.The higher the postoperative facial paralysis level,facial paralysis occurs.The earlier the time,the longer the facial makeup lasts.
