Relationship between growth of facial morphology and chronologic age in preschool children with obstructive sleep apnea

ABSTRACTBackgroundThe purpose of this study was to evaluate the relationship between facial morphology using cephalometry and chronologic age in preschool children with obstructive sleep apnea (OSA).Materials and MethodsFrom a group of lateral cephalometric radiographs taken of 35 children with OSA for diagnostic purposes, 15 were selected for the present investigation based on head position. The subjects consisted of preschool children with both OSA and primary dentition, all of them with a lowest documented SpO2 <90% and a lowest 0
