OBJECTIVE Obstructive sleep apnoea syndrome (OSAS) is a common problem in children. It is characterised by a combination of partial airway obstruction associated with hypoxemia and hypoventilation and intermittent obstructive apnoea, which disrupts normal ventilation and sleep. The aim of the study was to evaluate the craniofacial features of preschool children with polysomnographic diagnosis of OSAS, using measurements from standardized lateral cephalograms according to the floating norms cephalometric analysis. METHODS 21 untreated caucasian children (mean age of 4.57 +/-0.6) with complete deciduous dentition were included in this study. All the subjects had diagnosis of OSAS with a positive RDI. Pretreatment cephalometric radiographs were evaluated. Statistical method Descriptive statistics includes mean and standard deviation of the cephalometric variables. CONCLUSIONS The present study showed that OSAS preschool children showed a skeletal Class II pattern with retrognathic mandible and increased skeletal divergency.

D014716 Vertical Dimension The length of the face determined by the distance of separation of jaws. Occlusal vertical dimension (OVD or VDO) or contact vertical dimension is the lower face height with the teeth in centric occlusion. Rest vertical dimension (VDR) is the lower face height measured from a chin point to a point just below the nose, with the mandible in rest position.
