Study on acoustic rhinometry in the clinical application of children with obstructive sleep apnea hypopnea syndrome

Objective To explore the role of acoustic rhinometry in the clinical application of children with obstructive sleep apnea hypopnea syndrome(OSAHS).Methods Thirty-seven patients with OSAHS were measured with acoustic rhinometry and symptom score before and 4 weeks after adenoidectomy.Results In preoperative patients NV was(6.65±1.63) cm3,NPV was(8.07±2.64) cm3;After surgery NV was(9.49±2.15) cm3,NPV was(11.64±3.27) cm3.The NV and NPV after the surgery were significantly increased than that of before(P0.01).The change of NPV had negative correlation with symptom score.Conclusion Acoustic rhinometry is well tolerated by children with OSAHS,and is a rapid and noninvasive method.It could become a routine examination before and after adenoidectomy.
