摘要
目的:评价腭裂修复同期鼓膜切开中耳置管对腭裂渗出性中耳炎及听力损失的作用。方法:选择在腭裂修复前作声阻抗检查鼓室图为B型、声镫骨肌反射阴性、脑干听觉诱发电位检查V波反应≥30dB的患儿76例,随机分为A、B2组,A组45例在腭裂修复同期中耳置管,B组31例为单纯性腭裂修复,术后2周行鼓室图、脑干听觉诱发电位检查,结果采用t检验和χ2检验。结果:A组手术前与手术后V波反应阈值、听力损失及鼓室图均有显著性差异(P<0.001),B组手术前与手术后V波反应阈值、听力损失及鼓室图均无显著性差异(P>0.05),术前A、B2组间V波反应阈值、听力损失及鼓室图无显著性差异(P>0.05),术后A、B2组间V波反应阈值、听力损失及鼓室图有显著性差异(P<0.001)。结论:中耳置管可作为防治腭裂术后渗出性中耳炎及听力损失的常规治疗手段,避免黏连性中耳炎发生,提高患者听力。
PURPOSE： To investigate whether otitis media effusion （OME） in cleft palate patients could be prevented by tube insertion. METHODS： 76 patients with tympanometry B type in acoustic impedance audiometry, acoustic stapedial reflex negative, and V wave ≥30dB in brainstem auditory evoked potentials（BAEP） were randomly divided into 2 groups. In group A, 45 eases underwent palatoplasty and tube insertion simultaneously; in group B,31 cases underwent palatoplasty alone. All eases received tympanometry and BAEP reexamination 2 weeks after operation. Statistic analysis was carried out using SPSS 10.0 software package for Student＇s t test and Chi Square test. RESULTS： Significant difference existed between AP and PO threshold of response of V wave, hearing loss and tympanometry in group A before and after operation （P〈0.001）. Nevertheless, no significant difference existed in group B before and after operation （P〉 0.05）. No significant difference existed between group A and group B in AP threshold of response of V wave, hearing loss and tympanometry before operation （P〉0.05）, but, significant difference existed between group A and group B（P〈0.001） after operation. CONCLUSION： Tube insertion could prevent and cure OME and hearing loss after palatoplasty, and should be used routinely.
