In China, underlay tympanoplasty is used across the country, but the overlay tech-nique is used rarely. The aim of the current study was to report the authors’experience with overlay tympa-noplasty in 83 Chinese patients and study its value. Methods Eight-three patients (86 ears) underwent over-lay tympanoplasty in accordance to the standard of the HEC. The patients were followed up and conditions of the external auditory canal, tympanic membrane and hearing were reviewed and analyzed. Results All patients gained stage I incision healing. The size of external auditory canal and tympanic membrane mor-phology were satisfactory. Hearing either remained unchanged or improved. There were no hearing deterio-ration or serious complications. Conclusions Overlay tympanoplasty carries positive value in treating chron-ic otitis media and cholesteatoma with the merits of procedure standardization, adequate operative exposure, thorough disease elimination and extensive adaptation.展开更多
目的 观察自体乳突皮质骨粉行乳突填塞重建外耳道后壁的临床疗效。方法 43例慢性化脓性中耳炎或中耳胆脂瘤患者行乳突开放＋鼓室成形术后,应用自体乳突皮质骨粉填塞乳突术腔行外耳道后壁重建术,加耳甲腔成形术。结果 术后随访时间3~22个...目的 观察自体乳突皮质骨粉行乳突填塞重建外耳道后壁的临床疗效。方法 43例慢性化脓性中耳炎或中耳胆脂瘤患者行乳突开放＋鼓室成形术后,应用自体乳突皮质骨粉填塞乳突术腔行外耳道后壁重建术,加耳甲腔成形术。结果 术后随访时间3~22个月,平均13.4个月;所有病例均干耳,术后干耳时间为20-56 d,平均为31.7 d。言语频率（0.5、1、2 k Hz）平均纯音听力（pure tone average,PTA）气导由术前55.0±6.2 d B提高到术后34.0±3.2 d B,骨导由术前28.1±4.4 d B提高到术后21.5±4.1 d B,气骨导差（air-bone gap,ABG）由术前26.8±7.8 d B缩小到12.5±4.1 d B,术后听力提高成功率（术后PTA-ABG≤20 d B）为74.4%（32/43例）。除4例出现填塞骨粉感染、散落外,术后所有患者外耳道形态接近正常解剖结构,鼓膜形态正常,无再穿孔及内陷袋形成,外耳道后壁重建成功率为90.7%（39/43例）。结论 中耳乳突开放术后应用自体乳突皮质骨粉填塞乳突术腔行外耳道后壁重建术,是缩小乳突术腔,获得近似正常的外耳道解剖形态结构的有效方法。展开更多
目的评估完壁式乳突切除术(CWUM)联合鼓室成形术治疗慢性化脓性中耳炎(CSOM)的效果。方法 130例CSOM患者按照手术方式不同分为研究组(完壁式乳突切除术+鼓室成形术)与对照组(开放式乳突切除术+鼓室成形术),每组各65例。术后随访24个月,...目的评估完壁式乳突切除术(CWUM)联合鼓室成形术治疗慢性化脓性中耳炎(CSOM)的效果。方法 130例CSOM患者按照手术方式不同分为研究组(完壁式乳突切除术+鼓室成形术)与对照组(开放式乳突切除术+鼓室成形术),每组各65例。术后随访24个月,比较2组患者治疗前后纯音听力、术后主观听力改善、平均干耳时间及并发症情况。结果研究组与对照组术后24个月的纯音听阈阈值分别比术前降低22.59 d B和11.42 d B;组内手术前后及组间术后听力改善比较差异均有统计学意义(P值均<0.05)。研究组术后24个月主观听力改善优于对照组(P<0.05)。研究组与对照组术后干耳所需时间分别为49.16 d和36.95 d,组间差异具有统计学意义(P<0.05)。2组术后并发症发生率比较差异无统计学意义(P>0.05)。结论 CWUM联合鼓室成形术治疗CSOM对于符合适应证的患者,能够完整清除病灶,改善患者听力,疗效确切。手术医师需要根据患者病变情况合理选择CWUM或开放式乳突切除术。展开更多
