Importance of cephalographs in diagnosis of patients with sleep apnea.

Introduction: Obstructive sleep apnea (OSA) is considered to be a potentially life threatening disorder, which is characterized by repeated collapse of the upper airway during sleep with cessation of breathing. The cephalometric method despite being a static, two-dimensional evaluation of dynamic three-dimensional structures of the head and neck is useful in diagnosing patients with OSA, as they have shown that significant differences exist between asymptomatic controls and patients with OSA.

Aims And Objectives: This study is designed to compare and validate the craniofacial morphology in patients with OSA using lateral cephalometry in both upright and supine position.
