We studied 15 children of preschool age who had obstructive sleep apnea syndrome to evaluate their dentofacial morphology in relation to the pharyngeal airway space. We found that (1) sleep apnea was often associated with mandibular retrognathia, (2) the lower incisors tended to exhibit a retrocline, (3) there were no significant differences in angular and linear measurements in the cranial base between patients with sleep apnea and a control group of 30 nonapneic children, and (4) the apneic children had a narrower epipharyngeal airway space than did the controls. These findings suggest that obstructive sleep apnea is probably caused by both adenoidal hypertrophy and abnormal development of the facial skeleton. We highly recommend cephalometric analysis as a valuable tool for conducting the presurgical evaluation of sleep apnea in children of preschool age.
