Radical mastoidectomy and primary tympanoplasty under microscopy correlation analysis of therapeutic efficiency of hearing reconstruction

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.

Portmann氏耳后上进路全翻内植法修补鼓膜大穿孔45例报告

目的探讨Portmann氏耳后上进路全翻内植法修补鼓膜大穿孔的方法及疗效。方法采用耳后上进路,自体颞肌筋膜作为移植材料,对45例鼓膜大穿孔病人进行全翻外耳道后壁皮瓣鼓膜成形术,并对其临床资料进行回顾性分析。结果术后6个月随访,43例鼓膜穿孔愈合,2例出现鼓膜中央小穿孔,听力均有不同程度的提高。结论本术式术野暴露清晰,取颞肌筋膜在同一切口进行,修补鼓膜大穿孔成功率高,具有较高的临床应用价值。
