摘要: 目的:探讨耳内镜下改良夹层法鼓膜成形术的疗效。方法:采用耳内镜对43例(43耳)外伤性鼓膜穿孔、静止期的慢性化脓性中耳炎(单纯型)患者行改良夹层法鼓膜成形术。结果:43例患者术后均一次性成功修补鼓膜。术后6个月复查,1例有小穿孔;1例术后 7 d因上呼吸道感染致中耳流脓, 移植物脱落, 穿孔未愈合;1例失访。鼓膜穿孔愈合率为 95.2%。6个月后听力测试语言频率提高>15~20 dB HL者28耳,10~15 dB HL者8耳,6耳(包括未愈合2例)听力无变化。声阻抗测听检查,30耳为A型(其中12耳为As型,4耳为Ad型),6耳为B型,4耳为C型。结论:耳内镜下改良夹层法鼓膜成形术方法较简便,安全可靠,创伤小,临床效果好,值得推广。Abstract: Objective: To explore the curative effect of endotoscopic myringoplasty with modified sandwich technique.Method: Endotoscopic myringoplasty was performed with modified sandwich technique for traumatic perforation of tympanic membrane and chronic suppurative otitis media(simple type)of 43 patients.Result: All the perforating tympanic membranes were repaired successfully in one time. Six months after the operation,1 case was out of follow-up and 2 cases were falied:one got a small perforation when the transplantation shifted and the transplantation of the other one was lost because of infection. The closure rate of tympanic membrane perforations was 95.2%. The air-bone gap of speech frequency of 28 ears increased by >15-20 dB, 8 ears were enhanced by 10-15 dB, while 6 ears(including 2 failed cases) without improvement. The acoustic immittance test showed that "Type A","Type As","Type Ad","Type B" and "Type C" tympanogram were in 30 ears,12,4,6 and 4,respectively.Conclusion: The endotoscopic myringoplasty with modified sandwich technique has the advantages of simple operation, better security, less trauma and better efficacy, and it is worth popularizing.
