Effect of body position on tongue posture in awake patients with obstructive sleep apnoea.

摘要: BACKGROUND: Snoring and obstructive sleep apnoea (OSA) are worse or may only occur in the supine position. The effect of body position on upper airway size has been reported, but tongue posture not previously examined. METHODS: Detailed measurements were made from upright lateral cephalograms 24 men with OSA 13 non-apnoeic snoring matched for age, mass index, craniofacial skeletal pattern. Patients had apnoea/hypopnoea indices (AHI) > 50/hour and/or (AI) 25/hour while snorers AHI < 10/hour AI 5/hour. RESULTS: In depth superior-posterior portion larger than (p 0.05). There was no significant difference between patients OSA. CONCLUSIONS: When awake move to they maintain their which tend protect against collapse secondary increased gravitational load tongue. contrast, when a dorsal movement is observed.
