Abstract

Objectives: The severity of sleep apneas largely depends on abnormal size of upper airway. Therefore, nasal
examination is essential part of clinical evaluation of children with
sleep-disordered breathing.

Methods: We performed a
retrospective survey involving children aged 4 years and older which underwent
in-laboratory overnight cardiorespiratory polygraph study between January 2016
and May 2017. Nasal obstruction test was used to score severity.

Results: Fifty-three
children (62% males) with a median age of 6.1 (IQR 3.1) years were
enrolled in this study. Linear regression analysis showed that nasal
obstruction score was correlated with apnea-hypopnea index (β=0.345; p < 0.014) and oxygen desaturation
index (β=0.328; p < 0.022), whilst
no association was found with age, BMI Z-score, snoring and phase angle. Correlation analysis also
showed that nasal obstruction score was correlated with apnea-hypopnea index (r=0.364; p = 0.009) and oxygen desaturation index (r=0.350; p = 0.012) after adjustment for age and
BMI Z-score., but not with snoring time or phase angle degree.

Conclusions: Nasal obstruction test may be a useful, time saving
assessment which aid exploring sleep
disordered breathing in children. However, this test should not be used alone because it is plagued by objective consideration and at risk of under or overestimation.
