阻塞性睡眠呼吸暂停低通气综合征患儿听力变化

目的 探讨鼻内镜下腺样体切除前、后阻塞性睡眠呼吸暂停低通气综合征(obstructive sleep apnea hypopnea syndrome,OSAHS)患儿听力及中耳功能的变化.方法 选取诊断明确的扁桃体、腺样体肥大所致OSAHS患儿58例,患儿无耳聋家族史,无耳毒性药物应用史.术前纯音测听和声导抗检测患儿中耳功能及听力并记录.全麻下先切除双侧扁桃体,然后在30°内镜下用电动吸割器吸除腺样体,术后给予抗生素及激素全身应用,配合咽鼓管吹张及鼓膜按摩.术后随访3～12 个月.结果 78%(45/58)OSAHS患儿存在中耳功能异常.术后随访3～12 个月,伴听力下降患儿86%听力提高.结论 OSAHS伴听力下降患儿行腺样体和扁桃体切除术后听力可获得提高.

Effect of operation on the hearing in children with obstructive sleep apnea hypopnea syndrome

OBJECTIVE To study the effect of operation on the hearing in children with obstructive sleep apnea hypopnea syndrome.METHODS A total of 58 children with definitive OSAHS because of the hypertrophy of adenoid and tonsil were included in this study. All of them have no deafness family medical history and a history of application of ototoxic drug. Pure tone audiometry and acoustic immittance measurement were taken before and after operation. All the children underwent tonsillectomy and adenoidectomy. RESULTS 78 % of the children with OSAHS had abnormal function of the middle ear. After followed up for 3 to 12 months, the hearing was improved in 86 % of the children with hearing loss before operation. CONCLUSION Tonsillectomy and adenoidectomy may improved the hearing in OSAHS children with hearing loss.
