Abstract:
Objective To study the upper airway structure characteristics of children with obstructive sleep apnea hypopnea syndrome (OSAHS) using electronic pharyngorhinoscopy.Methods Seventy-eight children with OSAHS (34 cases mild group,44 cases moderate and severe group) and 52 children with chronic pharyngitis in the same period (control group) were selected.Each group was examined by electronic pharyngorhinoscopy.The adenoid-nasopharynx ratio (ANR),degree of palatopharyngeal anteroposterior diameter collapse,degree of palatopharyngeal right-and-left diameter collapse,degree of palatopharyngeal cavity collapse,degree of glossopharyngeal anteroposterior diameter collapse,degree of glossopharyngeal right-and-left diameter collapse,degree of glossopharyngeal cavity collapse were compared,and the relevance between thegn were analyzed.Results The ANR in mild group,moderately and severe group was significantly higher than that in control group (0.84 ± 0.21 and 0.69 ± 0.25 vs.0.34 ± 0.12),and the ANR in moderate and severe group was significantly higher than that in mild group.There were statistical differences (P ＜ 0.05).The degree of palatopharyngeal anteroposterior diameter collapse,degree of palatopharyngeal right-and-left diameter collapse,degree of palatopharyngeal cavity collapse,degree of glossopharyngeal anteroposterior diameter collapse,degree of glossopharyngeal right-and-left diameter collapse,degree of glossopharyngeal cavity collapse in moderately and severe group were significantly higher than those in control group and mild group (0.81 ± 0.25 vs.0.41 ± 0.17 and 0.54 ± 0.20,0.66 ± 0.23 vs.0.31 ±0.08 and 0.43 ±0.14,0.51 ±0.18 vs.0.14 ±0.04 and 0.23 ±0.11,0.55 ±0.21 vs.0.29 ±0.14 and 0.32 ± 0.13,0.69 ± 0.28 vs.0.42 ± 0.12 and 0.43 ± 0.11,0.33 ± 0.12 vs.0.10 ± 0.03 and 0.14 ± 0.05),and there were statistical differences (P ＜ 0.05).There were no statistical difference in the indexes between mild group and control group (P ＞ 0.05).In children with OSAHS,the ANR,degree of palatopharyngeal anteroposterior diameter collapse,degree of palatopharyngeal cavity collapse,degree of glossopharyngeal right-and-left diameter collapse,degree of palatopharyngeal cavity collapse were positively correlated with AHI (P ＜ 0.05),while there was no correlation between the degree of palatopharyngeal right-and-left diameter collapse,degree of glossopharyngeal anteroposterior diameter collapse and AHI (P ＞ 0.05).Conclusions Upper airway structural changes in children with OSAHS have certain correlation with the severity of sleep apnea.And there is clinical value by using electronic pharyngorhinoscopy in children with OSAHS to research airway morphology.
