鼻声反射在儿童阻塞性睡眠呼吸暂停低通气综合征诊断中的价值

目的：探讨鼻声反射在儿童阻塞性睡眠呼吸暂停低通气综合征（OSAHS）诊断中的价值。方法：对36例OSAHS患儿在术前及术后1个月分别进行鼻声反射检查,其中20例患儿术中用“排水法”对切除的腺样体实际体积进行测量,并与通过鼻声反射所得到的腺样体体积进行比较。结果：术后1个月患儿鼻咽部容积均明显高于术前。20例患儿术中用“排水法”所测得的腺样体实际体积要高于通过鼻声反射所得到的腺样体体积,但两者之间有明显的相关性。结论：在OSAHS患儿中,鼻声反射是评估腺样体大小的较好方法,可作为腺样体切除术前常规的检查方法之一。

Acoustic rhinometry in the diagnosis of children with obstructive sleep apnea-hypopnea syndrome

Objective:To explore the role of acoustic rhinometry in the diagnosis of children with obstructive sleep apnea-hypopnea syndrome(OSAHS).Method:Thirty-six patients with OSAHS were measured with acoustic rhinometry before and 1 month after adenoidectomy.Twenty patients with adenoidectomy were measured before and after operation,the changes in volume recorded by acoustic rhinometry were compared with the adenoid volume obtained by the method of "drain off the water".Result:The volume of nasopharynx of adenoid removal patients was significantly bigger than that of before operation.The adenoid volume of 20 patients obtained by the method of "drain off the water" was bigger than the calculated changes in nasopharynx volume recorded by acoustic rhinometry,however,they were found to be significantly interrelated.Conclusion:Acoustic rhinometry is a better method to calculate the size of adenoid in children with OSAHS and it could become a routine examination before adenoidectomy.
