Analysis Of The Effect Of Acoustic Neuroma Resection On Facial Nerve Function And Postoperative Complications In Patients With Acoustic Neuroma

Background and objectives:Acoustic neuroma is a benign intracranial tumor disease,which often occurs in the inner auditory canal and the pontine cerebellum.With the development of medical technology and the improvement of the quality of life,people’s health awareness has increased,and their willingness to treat has also increased.Therefore,the proportion of auditory neuroma discovery has increased,showing the characteristics of "early and small".Acoustic neuroma usually occurs only in the inner auditory canal in the early stage and does not affect the cerebellopontine angle region.Therefore,in the treatment of acoustic neuromas,clear and effective treatment methods are needed to enable patients to obtain good prognosis.At present,in the clinical treatment of acoustic neuromas,the main treatment measures are: dynamic follow-up observation,surgical treatment under the microscope,stereotactic radiotherapy,among which the surgical treatment under the microscope is always the first choice.To explore the effects of acoustic neuroma resection on facial nerve function and postoperative complications in patients with acoustic neuromas,and to provide a reference for clinical treatment of acoustic neuromas.Methods:A total of 40 patients with acoustic neuroma who were admitted to our hospital from April 2019 to April 2020 were selected for study.All patients were confirmed in our hospital.The clinical symptoms and basic signs exhibited by the patients were counted,and imaging examinations were performed for all patients before surgery to determine the grade,diameter,and lesions of the acoustic neuroma.After the operation,the patient’s postoperative recovery was observed,and the main factors affecting the facial nerve function of the patient were analyzed through multi-factor analysis.Results:(1)All patients who underwent total resection had a successful tumor resection.Another 4 patients had not cleared the tumor at one time.The resection rate was 90%,and no deaths occurred.(2)Facial nerves were retained in 35 patients after surgery,accounting for 87.5%.There were 23 hearing-preserving patients,accounting for 57.5%.(3)After treatment,a total of 4 complications occurred,including 1 case of postoperative cerebellar hemorrhage,1 case of intracranial infection,and 2 cases of incision cerebrospinal fluid leakage,accounting for 2.5%,2.5%,and 5%,respectively.(4)After treatment,only one of all patients relapsed,accounting for 2.5%.(5)After multivariate analysis,it was found that the main risk factor leading to abnormal facial nerve function after surgery was tumor size.(6)After the end of treatment,there were 8 patients who improved their hearing compared to before surgery,accounting for 32%,and 11 patients who had no significant changes compared with before surgery,accounting for 44%.After treatment,hearing and surgery Compared with the previous case,there were 6 cases of significantly decreased patients,accounting for 24%.Conclusion:Acoustic neuroma resection for patients with acoustic neuroma can effectively remove most of the diseased tissues,and whether it can preserve the facial nerve function and hearing of most patients.The incidence of adverse reactions after surgery is less and the safety is higher.The tumor size is the main influencing factor for the facial nerve function of patients after surgery.Therefore,patients with larger tumors should be given special attention,and personalized diagnosis and treatment programs should be implemented according to the patient’s occupation,age,and physical status.
