显微镜下乳突根治术并 I期骨室成形术与听力重建的相关性分析

Objective The aim of this article is to research the radical mastoidectomy and primary tympanoplasty to attain radical cure of the mastoid focus as well as rebuilding the sound- conducting structure of the tympanic cavity to improve the audition. Method The autobone and temporal fascia were taken as the transplants after the radical mastoidectomy under microscopy, and then to carry out the operation of Portmann｀ s tempanoplasty of 2nd and 3rd types of 2nd class.Result Non of the cholesteatoma was relapsed after follow- up for 1～ 4 years.The efficiency rate of tympanoplasty is of 89.47% .The average audition increased was 19 dB HL. Conclussion Radical operation for cholesteatoma should be associated with tympanoplasty if having condition. We recommend that the opening tympanoplasty should be used, and use autobone as a artificial auditory ossicles.     

泛影葡胺治疗突发性聋的疗效观察

目的 :探讨应用泛影葡胺治疗突发性聋的疗效 ;方法 :应用前瞻性的随机分组方法进行临床试验 ,分为泛影葡胺组及常规药物组 ,两组病人均常规给予扩张血管、改善微循环、营养神经治疗 ,泛影葡胺组在此基础上 ,应用泛影葡胺治疗 ;结果 :共收治突聋患者 72例 81耳 ,泛影葡胺组和常规药物组各 3 6例 ,泛影葡胺组总有效率为 85.4% ( 3 5 41 ) ,常规药物组为 67.5% ( 2 7 40 ) ,泛影葡胺组疗效明显高于常规药物组 (P <0 .0 5) ;结论 :突发性聋应用泛影葡胺治疗可明显提高疗效     

183例乳突根治术并I期鼓室成形术临床分析

目的探讨乳突根治术并I期鼓室成形术，以达到根治中耳乳突病灶的同时重建鼓室传音结构，改善听力。方法在显微镜下乳突根治术后，取自体骨及颞肌筋膜作移植物，行Portmann二类②型及③型鼓室成形术。结果追踪1～9年未发现胆脂瘤复发。鼓室成形有效率85．25％，平均听力提高21dB HL。结论行胆脂瘤根治术，有条件时，应并行鼓室成形术，支持开放式鼓室成形术，支持采用自体骨作人工听骨。
