【摘要】 目的探讨基层医院应用耳内镜技术开展鼓膜穿孔修补术的临床研究。方法在耳内镜下采用不同材料对鼓膜穿孔的54耳患者进行修补手术,并针对穿孔的大小和部位采用不同方法处理。结果随访3~6个月,平均3.4个月。鼓膜穿孔总愈合率为88.9%,其中脂肪92.3%、颞肌筋膜90%、软骨膜88.46%、软骨膜-软骨80%。比较差异无显著性(χ2=0.646,P>0.05),54耳的术前听力学检查均有不同程度的传导性听力下降,术后平均气导提高>10 dB者有38耳(70.4%)。结论基层医院开展耳内镜下鼓膜穿孔修补手术均能达到有效的治疗结果,适合推广应用,但移植材料要根据鼓膜穿孔大小和类型的不同合理选择。更多还原

【Abstract】 【Objective】To explore the clinical application of endotoscope in repairing the perforation of tympanic membrane in primary hospital. 【Methods】We analyzed the data from 54 patients operated on for a tympanic perforation using endotoscope with different graft. 【Results】 Patients were followed up postoperatively for 3 ~6 months. The average closure rate of tympanic membrane perforations was 88.9%(92.3% in fat group, 90% in temporal fascia group, 88.46% in perichondrium group and 80% in perichondrial cartilage group). The improvement in pure tone air conduction threshold more than 10 dBHL was achieved in 38 cases after operation, the difference was statistically significant(P <0.05). 【Conclusion】Endotoscopic myringoplasty is a rapid, safe, reliable and efficient procedure that should be performed in primary hospital. Different graft material should be chosen reasonably according to different size and type of the tympanic membrane perforation.更多还原
