【摘要】 目的 :探讨鼓室成形术治疗慢性化脓性中耳炎的疗效。方法 :4 3例耳慢性化脓性中耳炎行鼓室成形术 ,其中鼓室成形术Ⅰ型 2 6例 ,开放式乳突根治加鼓室成形术Ⅱ型 3例 ,开放式乳突根治加鼓室成形术Ⅲ型 14例。结果 :手术后听力提高明显(P <0 .0 0 1) ,手术成功率为 88.4 % ,干耳率 93.0 %。结论 :鼓室成形术Ⅰ型和鼓室成形术Ⅲ型能有效提高听力。耳甲腔成形和乳突腔骨膜瓣填充可增加干耳率。手术成功的关键在于病变的清理和重建中耳含气腔更多还原

【Abstract】 Objective:To explore the therapeutic effects of tympanoplasty on chronic suppurative otitis media.Methods:Forty three cases treated with tympanoplasty were retrospectively analyzed.Twnety six ears were performed type Ⅰ tympanoplasty,3 ears type Ⅱ tympanoplasty,plus open mastoidectomy,and 14 ears type Ⅲ tympanoplasty,plus open mastoidectomy.Results:All the cases were followed up for 6 to 12 months.Post operation hearing improvement was significant( P <0.001).Success rate of tympanoplasty was 88.4%.Drying ear rate was 93.0%.Conclusions:Type Ⅰ tympanoplasty and type Ⅲ tympanoplasty can improve hearing effectively.The plasty of cavity of auricular concha and mastoid obliteration can raise drying ear rate.The criterions of success are focuses clearance and reconstruction of air room in middle ear.
