Due to the lengthy observation period, the operative technique is recommended to do tympanotomy pipes, together with possibility of recurrence after tympanotomy is high.ObjectiveTo elucidate the medical attributes, medical strategy, facial neurological fix methods and results of facial nerve schwannomas（FNS）. MethodsThe medical information of patients with FNS managed between January 2010 and December 2018 at Sun Yat-sen Memorial Hospital of sunlight Yat-sen University were retrospectively collected, including the sidedness of FNS, clinical manifestations, imaging data, the degree of cyst, clinical management, preoperative and postoperative facial nerve function. ResultsThe significant clinical manifestations of the 32 patients with FNS had been facial palsy（27, 84.4%）, hearing loss（27, 84.4%）, tinnitus（22, 68.8%）, ear mass（15, 46.9%）, and stuffy experience when you look at the ear（13, 40.6%） respectively. Thirty clients were preoperatively identified as having FNS and 2 patients had been misdiagnosed. 31 patients underwent resection of FNS, except one patient who had been chosen for long-term follow-up observation. The decision of surgical method was based on the location, degree and auditory function of the FNS involtomosis. Among patients who underwent facial nerve repair,the best outcome was H-B Ⅲ. ConclusionThe patients with FNS mainly given facial palsy and hearing reduction. Temporal bone CT and cranial MR plain & enhanced scan served really to confirm the analysis. The enhancement price of postoperative facial nerve function had been substantially greater in patients who underwent neurological fix compared to those who did not. Hence, facial neurological repair should be considered. Compared with facial nerve-sublingual neurological anastomosis, auricular significant nerve-facial neurological graft could be a much better option for improving postoperative facial nerve function.ObjectiveTo explore the related factors of abrupt sensorineural hearing reduction difficult with ischemic swing, construct the chance forecast model Nirogacestat price , and verify the prediction effectation of the design. MethodsA retrospective evaluation had been carried out on 901 sudden sensorineural hearing loss patients hospitalized from January 2017 to December 2020, The clients were split into the ischemic stroke group（100 situations） and the unexpected deafness group（801 instances） based on whether they were difficult with ischemic swing, The independent correlation elements of unexpected deafness difficult infections: pneumonia with ischemic swing had been screened by univariate evaluation and multivariate Logistic regression model, as well as the threat forecast design and interior verification were founded. The original data had been randomly divided in to the modeling group（631 situations） plus the validation group（270 cases） at a 7∶3 ratio. Hosmer-Lemeshow and receiver operating characteristic curve were utilized to check the goodness of fit and predictive aftereffect of the model, and 27study programs good prediction effectiveness. which could offer sources when it comes to clinical screening of ischemic stroke dangers in clients with abrupt sensorineural hearing loss and early interventions during the early stage.ObjectiveTo explore the medical effectation of balloon dilatation associated with Eustachian tube along with myringotomy and catheterization in managing persistent recurrent secretory otitis media in adults. Methods100 cases（135 ears） of chronic recurrent secretory otitis media in our medical center from January 2018 to May 2020 were selected as the study objects, and had been divided into two groups according to the random number table method, 50 cases（68 ears） in the control group and 50 cases（67ears） in the observation team. The control group received tympanostomy and catheterization, whilst the observance group got tympanostomy with catheterization and balloon dilatation associated with Eustachian tube. The sum total efficient prices, Eustachian tube dysfunction scores, Eustachian pipe force R ratings, pure tone thresholds, complication rates, results of life high quality and recurrence rates 1 year after procedure were contrasted amongst the two teams submicroscopic P falciparum infections . ResultsThe complete efficient price had been higher in the observance group than the control e quality had been higher into the observance group compared to the control group（P less then 0.05）. ConclusionTympanotomy combined with balloon dilatation of Eustachian pipe can efficiently improve the Eustachian tube function of person customers with persistent recurrent secretory otitis news, it has impressiveclinical impacts. On the one hand,it can be more straightforward to market the recovery of customers’ hearing and enhance the clinical treatment rate of customers; Conversely, it reduce the occurrence of complications and infection recurrence considerably, therefore the quality regarding the customers’ life were improved considerably.ObjectiveTo explore the wideband absorbance qualities of patients with Meniere’s disease（MD）. MethodsWideband acoustic immittance was performed in 52 clients with unilateral Meniere’s disease（UMD） and 30 control subjects with regular hearing. All UMD patients underwent pure tone audiometry, 226 Hz acoustic immittance, wideband acoustic immittance, and gadolinium contrast MRI. Sixteen regularity points were selected to analyze the wideband absorbance at ambient and maximum force, plus the subjects were grouped as UMD team vs. control team and asymptomatic group. The student’s t-test had been used to compare the absorbance distinction between them.
