【摘要】 目的 探討乳突根治術后耳內窺鏡換藥與常規換藥相比是否具有優勢。 方法 2003年3月-2008年10月對89例共89只耳行開放式乳突根治術患者按隨機數字表法隨機分為試驗組及對照組，試驗組45例45只耳采用耳內窺鏡換藥，對照組44例44只耳常規換藥；分別觀察試驗組和對照組的干耳人數及干耳的時間，計算干耳率及干耳的平均時間。 結果 試驗組45只耳中42只干耳，干耳率93.3％；對照組44只耳中40只干耳，干耳率90.9％。兩組比較差異無統計學意義（Pgt;0.05）。試驗組42例干耳患者平均干耳時間為術后（50.8±13.4） d，對照組40例干耳患者平均干耳時間為術后（60.7±12.2） d；兩組比較，差異有統計學意義（Plt;0.001）。 結論 中耳乳突根治術后耳內窺鏡下換藥與常規換藥相比不能顯著提高干耳率，但能有效縮短干耳時間。【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.
【摘要】目的探討鼓膜置管對鼻咽癌(NPC)患者放療前后分泌性中耳炎(SOM)的療效。方法2005年3月2010年1月將60例(84耳)NPC并發SOM患者分為兩組:A組30例行鼓膜切開鼓膜置管;B組30例保守治療為對照組,并行隨訪,對兩組患者有效率和并發癥發生率進行統計。結果60例中58例存活,1例死于全身衰竭,1例死于大出血。存活患者中治療SOM有效率為:A組85.4%(35/41),B組為30.2%(13/43),兩組差異有統計學意義(Plt;0.05);并發癥發生率A組為14.6%(6/41),B組為69.8%(30/43),B組并發癥高于A組,差異有統計學意義(Plt;0.05)。結論NPC患者在放療后,咽鼓管功能受到嚴重損害,是不可逆的病變,鼓膜置管治療NPC并發SOM較保守治療效果好,并發癥的發生率低。
摘要:目的:探討兒童分泌性中耳炎的臨床特點及不同治療方案的效果.方法:回顧性分析84例分泌性中耳炎患兒的臨床資料及其相關因素,并收集資料完整的22例做治療前后的對比。結果:84例患兒中有73.8%存在鼻咽或口咽部病變,另有繼發于感冒占8.33%,伴有先天性聽力障礙占3.65%,例原因不明占總14.29%,鼓膜穿刺并置管同時切除增殖體病變后,聽力顯著提高(Plt;0.05)。結論:對反復發作的SOM患兒應行鼓膜置管,保留6個月以上,同時鼻咽和口咽部伴發病變應引起臨床醫生的重視,積極處理相關疾病。
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.
Objective To evaluate the diagnosis value of temporal Done high-resolution computed tornography (HRCT) in cholesteatoma. Methods There were 30 causes that had received the mastoid surgery because of cholesteatoma. Each patient’s mastoid plain films (Schuller’s and Mayer’s ) and HRCT had been taken and compared with each other and surgical findings and evaluated with health economic evaluation methods. Results The sensitivity rate in diagnosing cholesteatoma with HRCF was much higher than that with mastoid film (Plt;0.005). The more important benefit with HRCT was that it can afford the detail information in ear such as the ossicular chain, facial nerve canal, tympanic sinus, etc. which were basis for otologist in surgery to remove the focus thoroughly and reconstruct the middle ear function at the same time. In the view of health economic evaluation, HRCT is also much better than mastoid X-ray film. Conclusion HRCT should replace masloid Schuller’s and Mayer’s film in diagnosis cholesteatoma and HRCT should use as ordinary examination in chronic otitis media.
目的 系統評價標準桃金娘油治療分泌性中耳炎的療效及安全性。 方法 電子檢索Cochrane圖書館、PubMed、EMBASE、中國期刊全文數據庫（CNKI）、維普（VIP）、中國生物醫學文獻數據庫（CBM）六大數據庫，檢索時間自建庫截止至2012年2月。根據Cochrane協作網手冊評估納入隨機對照試驗（RCT）的方法學質量，采用RevMan 5.0軟件對數據進行Meta分析。 結果 共納入8個RCT，研究結果顯示，標準桃金娘油聯合常規治療分泌性中耳炎的總有效率優于單用常規治療，但差異無統計學意義[RR=1.21，95% CI（0.98，1.50），P=0.08]。 結論 標準桃金娘油治療分泌性中耳炎有一定療效，但并不顯著。因納入研究質量較低，上述結論還需高質量、大樣本的研究進一步驗證。
Objective To assess the effectiveness and safety of adenoidectomy on otitis media with effusion (OME) in children. Methods Electronic databases were searched including Medline (1966-2001), EMbase (1974-2001), the Cochrane Controlled Trials Register (CCTR), Chinese Biomedical Database (CBM, 1989-2001). Five Chinese otolaryngology journals were handsearched. References of eligible studies were also screened for inclusion. Selection criteria were restricted to randomized controlled trials comparing adenoidectomy with other treatments in patients with OME in children. At least two reviewers independently assessed trial quality and extracted data. RevMan 4.1 was used for statistical analysis. Results Of the 248 literatures identified, 13 trials with 1 430 patients were eligible and were included in the systematic review. Overall, the methodological quality of the included trials was high, all from developed countries. None of the trials showed that the effects of adenoidectomy better than those of myringotomy and no treatments for OME in children. Four trials comparing adenoidectomy with grommets showed that the effects of grommets were better than those of adenoidectomy. Ten trials described post-surgical bleeding, velopharyngeal incompetence and nasopharyngeal stenosis. Conclusions At present, there is no evidence to either ascertain that adenoidectomy is better than other treatments for OME, or to suggest which type of surgery is the most effective one. Current trials indicate that early administration of adenoidectomy concomitant with grommets might be the most appropriate therapy for OME in children who fail to response to drug treatment, if multiple risk factors exist.
