Sleep related breathing disorder (SRBD) is a modern concept applied to various diseases in which there is abnormal ventilation during sleep.Simple snorers and patients with obstructive sleep apnea syndrome (OSAS) are included.in this concept of breathing disorders caused by stenosis of the upper airway during sleep.<BR>However, the causes of stenosis of the upper airway have not yet been elucidated. Narrowing of the upper airway during arousal is thought to be a major factor.<BR>Therefore, we examined the faucial size in patients with SRBD, simple snorers and patients with OSAS, who had faucial stenosis.<BR>The subjects were 53 healthy individuals, who were on the medical staff or received routine examinations at Saiseikai Nakatsu Hospital between August 1990 and July 1992 and 20 patients treated in the outpatient otolaryngology department of Osaka Medical College Hospital between August 1992 and August 1994.<BR>With mesopharyngometry, anatomical characteristics were evaluated in normal controls, SRBD patients with low esophageal pressure (Pes) and SRBD patients with elevated Pes.<BR>Anatomical differences were found between normal controls and patients with SRBD. Patients with elevated Pes had significantly narrower fauces than did the normal controls or those with low Pes. Thus, deterioration in patients with SRBD could be due to faucial stenosis.
