摘要
目的测量耳屏软骨-软骨膜复合体厚度,探讨其对中耳炎手术治疗效果及重建听力的影响。方法 49例(50耳)慢性中耳炎患者根据病情行伴或不伴乳突根治的鼓室成形术,均以耳屏软骨-软骨膜复合体修补鼓膜,术中测量耳屏软骨-软骨膜复合体厚度,术后每周随访一次至干耳,术后半年复查纯音听阈,分析耳屏软骨-软骨膜复合体厚度、干耳与否、干耳时间、鼓膜生长情况、术前和术后半年0.5、1.0、2.0、3.0kHz频率的纯音听阈。结果 50耳耳屏软骨-软骨膜复合体的平均厚度为0.87±0.08mm(0.721.07mm),干耳时间31.07mm),干耳时间312w,中位数3w;42耳术后随访半年,鼓膜形态、色泽良好;其中31耳患耳气骨导差缩小,听力提高,另11耳听力结果未纳入分析。结论耳屏软骨-软骨膜复合体的厚度较恒定,作为修复中耳材料具有干耳时间较短、利于听力改善、并发症较少等特点。
