【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(0.72~1.07mm),干耳时间3~12w,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。
[Abstract]:Objective to measure the thickness of cartilage-cartilage complex in ear screen and to explore the effect of cartilage-cartilage complex on surgical treatment of otitis media and reconstruction of hearing. Methods 49 patients (50 ears) with chronic otitis media underwent tympanoplasty with or without mastoidectomy. The tympanic membrane was repaired with earscreen cartilage-cartilage periosteum complex, and the thickness of ear screen cartilage-cartilage periosteum complex was measured during operation. Follow-up to the dry ear once a week after operation. The pure tone hearing threshold was reexamined half a year after operation. The thickness of cartilage-cartilage complex, dry ear, dry ear time and tympanic membrane growth were analyzed. The pure tone hearing threshold of 0.5, 1.0, 2.0 and 3.0 kHz frequencies before and half a year after operation. Results the average thickness of cartilage-cartilage complex in 50 ears was 0.87 卤0.08mm (0.72~1.07mm). The dry ear time was 3 鈮，
