【摘要】目的探讨鼓膜置管对鼻咽癌(NPC)患者放疗前后分泌性中耳炎(SOM)的疗效。方法2005年3月2010年1月将60例(84耳)NPC并发SOM患者分为两组:A组30例行鼓膜切开鼓膜置管;B组30例保守治疗为对照组,并行随访,对两组患者有效率和并发症发生率进行统计。结果60例中58例存活,1例死于全身衰竭,1例死于大出血。存活患者中治疗SOM有效率为:A组85.4%(35/41),B组为30.2%(13/43),两组差异有统计学意义(Plt;0.05);并发症发生率A组为14.6%(6/41),B组为69.8%(30/43),B组并发症高于A组,差异有统计学意义(Plt;0.05)。结论NPC患者在放疗后,咽鼓管功能受到严重损害,是不可逆的病变,鼓膜置管治疗NPC并发SOM较保守治疗效果好,并发症的发生率低。
【摘要】 目的 探讨乳突根治术后耳内窥镜换药与常规换药相比是否具有优势。 方法 2003年3月-2008年10月对89例共89只耳行开放式乳突根治术患者按随机数字表法随机分为试验组及对照组，试验组45例45只耳采用耳内窥镜换药，对照组44例44只耳常规换药；分别观察试验组和对照组的干耳人数及干耳的时间，计算干耳率及干耳的平均时间。 结果 试验组45只耳中42只干耳，干耳率93.3％；对照组44只耳中40只干耳，干耳率90.9％。两组比较差异无统计学意义（Pgt;0.05）。试验组42例干耳患者平均干耳时间为术后（50.8±13.4） d，对照组40例干耳患者平均干耳时间为术后（60.7±12.2） d；两组比较，差异有统计学意义（Plt;0.001）。 结论 中耳乳突根治术后耳内窥镜下换药与常规换药相比不能显著提高干耳率，但能有效缩短干耳时间。【Abstract】 Objective To evaluate the application of otoendoscope in dressing change after mastoidectomy. Method Between March 2003 and October 2008, 89 patients (89 ears) underwent mastoidectomy in Department of Otolaryngology Head and Neck Surgery, West China Hospital of Sichuan University and in Department of Otolaryngology, Nuclear Industry 416 Hospital of Chengdu. The patients were randomly divided into two groups by simple randomization (trial group and control group). Forty-five patients in the trial group underwent the dressing change under otoendoscope, while 44 patients in the control group under the routine method. The ear drying rate and the ear drying time in the two groups were observed. Results The ear drying rate was 93.3% (42 dry ears)in the trial group, and was 90.9% (40 dry ears) in the control group; the difference between the two groups was not significant (Pgt;0.01). The ear drying time was (50.8±13.4) days in the trial group and was (60.7±12.2) days in the control groups; the difference between the two groups was significant (Plt;0.001). Conclusion Dressing change under the otoendoscope after mastoidectomy may not improve the ear drying rate but can shorten the ear drying time.
Otitis media is one of the common ear diseases, and its accurate diagnosis can prevent the deterioration of conductive hearing loss and avoid the overuse of antibiotics. At present, the diagnosis of otitis media mainly relies on the doctor's visual inspection based on the images fed back by the otoscope equipment. Due to the quality of otoscope equipment pictures and the doctor's diagnosis experience, this subjective examination has a relatively high rate of misdiagnosis. In response to this problem, this paper proposes the use of faster region convolutional neural networks to analyze clinically collected digital otoscope pictures. First, through image data enhancement and preprocessing, the number of samples in the clinical otoscope dataset was expanded. Then, according to the characteristics of the otoscope picture, the convolutional neural network was selected for feature extraction, and the feature pyramid network was added for multi-scale feature extraction to enhance the detection ability. Finally, a faster region convolutional neural network with anchor size optimization and hyperparameter adjustment was used for identification, and the effectiveness of the method was tested through a randomly selected test set. The results showed that the overall recognition accuracy of otoscope pictures in the test samples reached 91.43%. The above studies show that the proposed method effectively improves the accuracy of otoscope picture classification, and is expected to assist clinical diagnosis.
In order to study the influence of tympanic membrane lesion and ossicular erosion caused by otitis media on the hearing compensation performance of round-window stimulation, a human ear finite element model including cochlear asymmetric structure was established by computed tomography (CT) technique and reverse engineering technique. The reliability of the model was verified by comparing with the published experimental data. Based on this model, the tympanic membrane lesion and ossicular erosion caused by otitis media were simulated by changing the corresponding tissue structure. Besides, these simulated diseases’ effects on the round-window stimulation were studied by comparing the corresponding basilar-membrane’s displacement at the frequency-dependent characteristic position. The results show that the thickening and the hardening of the tympanic membrane mainly deteriorated the hearing compensation performance of round-window stimulation in the low frequency; tympanic membrane perforation and the minor erosion of ossicle with ossicular chain connected slightly effected the hearing compensation performance of round-window stimulation. Whereas, different from the influence of the aforementioned lesions, the ossicular erosion involving the ossicular chain detachment increased its influence on performance of round-window stimulation at the low frequency. Therefore, the effect of otitis media on the hearing compensation performance of round-window stimulation should be considered comprehensively when designing its actuator, especially the low-frequency deterioration caused by the thickening and the hardening of the tympanic membrane; the actuator’s low-frequency output should be enhanced accordingly to ensure its postoperative hearing compensation performance.

Methods We retrospectively analyzed the audiologic data of 382 patients diagnosed with chronic suppurative otitis media treated in our hospital from August 2005 to December 2008. Results The number of male chronic suppurative otitis media patients was more than female patients, and single ear infections are more than infections of both ears. The onset of the disease could be at any age. Most of the patients had a moderate conductive hearing loss. All kinds of tympanogram were found,and ear canal volume of the patients was enlarged. Conclusion Chronic suppurative otitis media is a common disease of the ear, which needs timely treatment, and audiological tests are important in guiding treatment plans and assessing prognosis.
