Objective: To compare results of upper airway dimensions with cephalometry in different posture. Methods: A detailed cephalometric analysis was performed using lateral X-ray films in sitting position and supine position from 30 male volunteers. Results: In the supine position, the mandibular and hyoid bone was displaced; the posterior airway space (PAS) turned more narrow compared with sitting position. Conclusions: Lateral X-ray film in supine position is highly recommended as a valuable tool in the diagnosis, treatment option and prognoses evaluation of obstructive sleep apnea syndrome(OSAS).
