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 effect of tympanic cavity on postoperative dry ear after conventional open surgery in middle ear surgery. Methods: A retrospective analysis of 168 cases of middle ear surgery, according to whether the operation after tympanic group open, the two groups of postoperative dry ear rate. Results: The postoperative dry ear rates of unopened tympanic group and open tympanic group were 81.7% (67/82) and 91.9% (79/86), respectively. After unopened, the patients with cholesteatoma and ulcerative type The rates of dry ears were 78.9% (30/38) and 84.1% (37/44) respectively. The rates of dry ears were 88.1% (37/42) and 95.5% (42/44) in the tympanic group after opening, respectively. Postoperative open ear tympanoplasty group tympanotomy and tympanoplasty postoperative dry ear rates were 81.8% (36/44) and 84.6% (31/38), while the open tympanum group were 91.3% (42 / 46) and 92.5% (37/40). CONCLUSION: The common open tympanic cavity in middle ear surgery is not only conducive to the clean-up of the hidden lesions, but also helps to maximally repair the facial nerve crest, relieve the drainage and finally improve the postoperative dry ear rate.
