Analysis of abnormal jaw development in children with obstructive sleep apnea hypopnea syndrome and its influencing factors and countermeasures
Objective To study the abnormal jaw development in children with obstructive sleep apnea hypopnea syndrome(OSAHS)and its influencing factors and countermeasures.Methods A total of 98 children with OSAHS were divided into an observation group(49 cases)and a control group(49 cases)according to whether there was abnormal jaw development.All the patients were measured by medical digital radiography(DR)and jaw DR imaging:X-ray cephalometric measurements of posterior airway space(PAS),SNA angle reflecting maxillary protuberance and SNB angle reflecting mandibular protuberance,maxillary width,and mandibular length,width,and height.The maxillofacial measurement indexes of the two groups were compared,and the correlation of SNA,SNB,PAS with apnea hypopnea index(AHI)and lowest blood oxygen saturation(LSaO2)was analyzed.Results There were no significant differences in maxillary width,mandibular length,mandibular width and mandibular height between the two groups(P>0.05).The observation group had SNA of(82.34±2.45)°,SNB of(83.83±3.17)° and PAS of(11.13±2.35)mm,which was statistically significant from(81.31±2.52)°,(82.53±2.34)° and(6.35±2.12)mm in the control group(P<0.05).The items with statistically significant differences in the t test of independent samples were correlated with AHI and LSaO2 respectively.The results showed that SNA was negatively correlated with AHI,SNA was positively correlated with LSaO2,SNB and PAS were positively correlated with AHI,and SMB and PAS were negatively correlated with LSaO2(P<0.05).Conclusion For children with OSAHS,SNA,SNB and PAS levels are significantly correlated with AHI and LSaO2,which affect the early jaw development of children to a certain extent,and should be detected and intervened in a timely manner.
