目的探讨耳内窥镜下鼓膜置管联合腺样体切除术治疗分泌性中耳炎(OME)患儿的临床疗效。方法选取2021年1月~2022年3月SOM患儿120例,按术式分为穿刺组(n=60)和置管组(n=60),穿刺组给予耳内窥镜下鼓膜穿刺联合腺样体切除术,置管组给予耳内窥镜下鼓膜置管联合腺样体切除术,比较两组积液消退时间、听觉脑干诱发电位(ABR)阈值、ABRⅠ波潜伏期、干扰素γ(IFN-γ)、白细胞介素6(IL-6)、肿瘤坏死因子α(TNF-α)、治疗效果以及并发症。结果置管组积液消退时间显著低于穿刺组,差异有统计学意义(P<0.05);穿刺组和置管组术后ABR、ABRⅠ波潜伏期、IFN-γ、IL-6和TNF-α均显著低于术前(P均<0.05);置管组术后ABR、ABRⅠ波潜伏期、IFN-γ、IL-6和TNF-α均显著低于穿刺组,差异有统计学意义(P均<0.05);置管组治疗有效率显著高于穿刺组,差异有统计学意义(P<0.05);置管组并发症发生率显著低于穿刺组,差异有统计学意义(P<0.05)。结论耳内窥镜下鼓膜置管联合腺样体切除术可有效改善SOM患儿听力及炎症,有利于提高疗效,且可减少并发症,值得临床推广。

Assessment of Balance and Vestibular Functions in Patients with Idiopathic Sudden Sensorineural Hearing Loss

This study investigated the relationship among the severity of hearing impairment,vestibular function and balance function in patients with idiopathic sudden sensorineural hearing loss（ISSNHL）.A total of 35 ISSNHL patients（including 21 patients with vertigo） were enrolled.All of the patients underwent audiometry,sensory organization test（SOT）,caloric test,cervical vestibular-evoked myogenic potential（cV EMP） test and ocular vestibular-evoked myogenic potential（o VEMP） test.Significant relationship was found between vertigo and hearing loss grade（P=0.009）,and between SOT VEST grade and hearing loss grade（P=0.001）.The abnormal rate of o VEMP test was the highest,followed by the abnormal rates of caloric and c VEMP tests,not only in patients with vertigo but also in those without vertigo.The vestibular end organs were more susceptible to damage in patients with vertigo（compared with patients without vertigo）.Significant relationship was found between presence of vertigo and SOT VEST grade（P=0.010）.We demonstrated that vestibular end organs may be impaired not only in patients with vertigo but also in patients without vertigo.The cochlear and vestibular impairment could be more serious in patients with vertigo than in those without vertigo.Vertigo does not necessarily bear a causal relationship with the impairment of the vestibular end organs.SOT VEST grade could be used to reflect the presence of vertigo state in the ISSNHL patients.Apart from audiometry,the function of peripheral vestibular end organs and balance function should be evaluated to comprehensively understand ISSNHL.Better assessment of the condition will help us in clinical diagnosis,treatment and prognosis evaluation of ISSNHL.

改良开放和完壁式乳突根治鼓室成形术对慢性中耳病变患者听力改善效果的影响

目的探讨改良开放和完壁乳突根治鼓室成形术对慢性中耳病变患者平均纯音听阈(pure tone audiometry,PTA及骨导值的影响。方法回顾性纳入河南省中医院2015年1月~2018年1月收治慢性中耳病变患者共176例,其中84例采用改良开放乳突根治鼓室成形术治疗设为A组,另92例采用完壁乳突根治鼓室成形术设为B组。比较两组术后复发率、术后干耳率、术后PTA下降值、术后骨导下降值、术后气骨导差下降值、术后听力频率阈下降值及并发症发生情况。结果两组术后PTA下降值、术后骨导下降值及术后气骨导差下降值比较差异无统计学意义(P>0.05);两组术后250、500、1000、2000 Hz听力频率阈下降值比较差异无统计学意义(P>0.05);B组术后4000 Hz听力频率阈下降值显著小于A组(P<0.05)。结论相较于完壁乳突根治鼓室成形术,改良开放乳突根治鼓室成形术治疗慢性中耳病变可获得相近听力改善效果。

Awake craniotomy for auditory brainstem implant in patients with neurofibromatosis type 2:Four case reports

BACKGROUND The auditory brainstem implant(ABI)is a significant treatment to restore hearing sensations for neurofibromatosis type 2(NF2)patients.However,there is no ideal method in assisting the placement of ABIs.In this case series,intraoperative cochlear nucleus mapping was performed in awake craniotomy to help guide the placement of the electrode array.CASE SUMMARY We applied the asleep-awake-asleep technique for awake craniotomy and hearing test via the retrosigmoid approach for acoustic neuroma resections and ABIs,using mechanical ventilation with a laryngeal mask during the asleep phases,utilizing a ropivacaine-based regional anesthesia,and sevoflurane combined with propofol/remifentanil as the sedative/analgesic agents in four NF2 patients.ABI electrode arrays were placed in the awake phase with successful intraoperative hearing tests in three patients.There was one uncooperative patient whose awake hearing test needed to be aborted.In all cases,tumor resection and ABI were performed safely.Satisfactory electrode effectiveness was achieved in awake ABI placement.CONCLUSION This case series suggests that awake craniotomy with an intraoperative hearing test for ABI placement is safe and well tolerated.Awake craniotomy is beneficial for improving the accuracy of ABI electrode placement and meanwhile reduces non-auditory side effects.

Effect of hypoglycemic anti-deafness capsules in diabetic patients with deafness and toxicological assessment in rats

OBJECTIVE:Through experiment on animals and clinical trials to explore the safety and efficacy of hypoglycemic anti-deafness capsules on diabetic patients with deafness.METHODS:Total 296 patients with non-insulin dependent diabetes mellitus(NIDDM)were randomly divided into two groups.A treatment group of 164patients(208 ears)was treated with hypoglycemic anti-deafness capsules based onTCM syndrome differentiation.A control group of 132 patients(184ears)was treated with glibenclamide and conventional drug treatment for deafness.The following were observed:hearing,fasting plasma glucose(FPG),2 h postprandial plasma glucose(2hPG),24 h urine glucose(24hUG),improvement of main symptoms,platelet function,and changes in superoxidedismutase(SOD)and lipid peroxide(LPO)levels.In animal studies,Kunming mice,weighing 18-22 g were used.Half of the mice were males and half were females.Wistar rats,weighing 80-120 g were used.Half of the rats were males and half were females.Male Wistar rats,weighing 200-220 g,were also used.Their acute and chronic toxicity was studied.RESULTS:The hearing improvement was 56.7%in the treatment group and 26.6%in the control group.FPG,2hPG,and 24hUG were improved significantly(P<0.05,P<0.01,P<0.01,respectively)in the treatment group and 2hPG and 24hUG improved significantly in the control group(P<0.05,P<0.05).The improvement in 2hPG and 24hUG in the treatment group was significantly greater than that in the control group P<0.01).There was no significant difference in FPG between the two groups(P<0.05).Main symptoms in the treatment group were significantly more improved than those in the control group(P<0.05,P<0.01).In the treatment group,platelet adhesion and aggregation,SOD,and LPO were all significantly improved from before treatment(P<0.05,P<0.01).However,in the control group,except LOP(P<0.05),there were no significant differences from before treatment to after(P<0.05).In animal studies,no obvious acute or long-term toxicity was observed from capsule administration.CONCLUSION:Through experiment on animals and clinical trials,we can found that hypoglycemic anti-deafness capsules could decrease blood glucose and serum triglycerides of alloxan-induced diabetic rats.This herbal capsule is effective for safely treating diabetic patients with deafness.
