The status of cephalometry in the prediction of non-CPAP treatment outcome in obstructive sleep apnea patients

摘要: Obstructive sleep apnea syndrome (OSAS) is the most common disordered breathing disorder (SDB) in adults and characterized by a recurrent partial or complete collapse of upper airway during sleep. This can be caused many factors, sometimes interacting, such as skeletal malformations, soft tissue crowding, respiratory instability various effects aging, obesity gender that dictate craniofacial anatomy. Research has demonstrated majority patients exhibit at least one anatomical component retrognathia narrow posterior space predisposes to development OSAS. Within predisposing elements for OSAS seem point characteristics. A standardized relatively simple radiologic technique evaluate relationships cephalometry. been used already long time orthodontics, but now gradually being introduced treatment envisage optimal selection well predict outcomes. The purpose present review contribution cephalometry prediction outcomes from treatments depend on morphology their mechanisms action oral appliances advance mandible surgical methods. In addition, an overview imaging modalities methods currently are cephalometric analysis provided. findings indicate isolated parameters cannot reliably mandibular advancement devices Extreme outlying values may rather contra-indicators 'red flags' instead predictors.
