摘　　要：目的:探讨中耳手术中常规开放后鼓室对术后干耳的影响。方法:回顾性分析168名中耳手术病例,按术中是否开放后鼓室分组,比较2组术后干耳率。结果:未开放后鼓室组和开放后鼓室组术后干耳率分别为81.7%(67/82)和91.9%(79/86);未开放后鼓室组中胆脂瘤型和骨疡型患者干耳率分别为78.9%(30/38)和84.1%(37/44),开放后鼓室组这2型干耳率分别为88.1%(37/42)和95.5%(42/44);未开放后鼓室组中行乳突根治术和鼓室成形术患者术后干耳率分别为81.8%(36/44)和84.6%(31/38),而开放后鼓室组则分别为91.3%(42/46)和92.5%(37/40)。结论:中耳手术中常规开放后鼓室不仅有利于清理隐匿的病灶,而且有利于最大限度的修低面神经嵴,通畅引流,最终提高术后干耳率。Objective：To investigate the influence of drying the ear canal by cleaning the focus of infection in the posterior tympanum in middle ear operations. Method.-Retrospectively analyze 168 cases of middle ear operations ,which were divided into two groups by whether the posterior tympanum was open or not in the operation process. Then compareing the drying ear rate. Result： The drying ear rate （DEC） were 81. 7% （67/82） and 91.9 % （79/86） in the posterior tympanum unopened and opened group, respectively. In the posterior tympanum unopened group , the DEC rate were 78.9% （30/38） and 84. 1% （37/44）in 38 cases of chronic otitis media and mastoiditis with cholesteatoma and in 44 cases of chronic otitis media and mastoiditis with granulation tissue, respectively. In the posterior tympanum opened group, the DEC rate were 88. 2%（37/42）and 94.7% （42/44）in 42 cases of chronic otitis media and mastoiditis with cholesteatoma and in 44 cases of chronic otitis media and mastoiditis with granulation tissue, respectively. In the posterior tympanum unopened group, the DEC rate were 81.7% （36/44）and 84.6% （34/38）in 44 cases of radical mastoidectomy and in 38 cases of tympanoplasty; compared with the posterior tympanum opened group, the DEC rate were 91.3% （42/46） and 92.5% （37/40） correspondingly. Conclusion：In the middle ear operation, open the posterior tympanum in convention can not only have profits to clear the insidious focus of infection , but also have profits to skeletonize to lower facial ridge to the utmost limits and make the drainage of the ear canal easy and smooth. At last, the rate of DEC was raised.
