Abstract

CONCLUSION:

Nasal resistance and the OSA-18 score were useful for evaluating surgical treatments. The sleep disturbance score may also be useful for predicting the severity of obstructive sleep apnea (OSA) in children.

OBJECTIVE:

We evaluated the effect of surgery on children with OSA using polysomnography (PSG) parameters, nasal resistance, and the OSA-18 questionnaire, and also investigated the cut-off OSA-18 score to screen for pediatric OSA.

METHODS:

This was a retrospective study in which PSG parameters and nasal resistance were measured using a rhinomanometer and the OSA-18 score was obtained from the OSA-18 questionnaire before and after surgery in 45 children with OSA.

RESULTS:

The mean age of the 45 patients was 5.7 ± 2.0 years. The mean value of the obstructive apnea hypopnea index (O-AHI) improved from 16.2 ± 14.3/h before surgery to 1.1 ± 1.7/h after surgery, the mean nasal resistance improved from 0.44 ± 0.19 to 0.32 ± 0.10 Pa/cm(3)/s, and the mean OSA-18 score improved from 61.1 ± 13.7 to 30.4 ± 5.8, and all these improvements were significant. The O-AHI value was lower than 1/h after surgery in 64.4% of patients (29/45). The O-AHI value was significantly correlated with the sleep disturbance score (r = 0.352, p = 0.018). When the cut-off OSA-18 score for screening was set at 40, sensitivity was 100%.
