阻塞性睡眠呼吸暂停综合征(OSAS)是由于上呼吸道间歇性萎陷所致,呼吸道解剖异常和肌张力过低均可诱发。OSAS多见于肥胖者。为测定上呼吸道解剖异常对本病的影响,作者对25例男性成人患者作了多导睡眠记录器的检查。他们每小时呼吸暂停次数为29～87次,平均62次。病人均有嗜睡,并有典型的OSAS表现。作者们还对呼吸道进行直接观察和纤维镜检;对口咽、喉咽和喉可能阻塞的部位测定其前后径和横径。对异常处由检查者和二位根据电视录像进行观察者共同评定,以取得近似的评分。结果发现所有患者均有呼吸道异常。如口咽部有悬雍垂所致的前后径缩小,侧壁凸出造成横径缩小。下咽部,舌根大的前后径缩小,会厌水 Obstructive sleep apnea syndrome (OSAS) is due to intermittent collapse of the upper respiratory tract, airway anatomy and hypotonia can be induced. OSAS more common in obese people. To determine the impact of upper airway anatomy on this disease, the authors performed polysomnography tests on 25 adult male patients. Their number of apnea hours per hour was 29 to 87, an average of 62. Patients have lethargy, and have a typical OSAS performance. The authors also performed direct observation of the respiratory tract and fiber microscopy; measured anteroposterior, hypopharyngeal, and laryngeal obstruction sites before and after the diameter and diameter. The abnormalities were jointly evaluated by the examiner and two observers based on the video recording to obtain an approximate score. The results showed that all patients have respiratory abnormalities. If the oropharyngeal uvula caused by the anteroposterior diameter is reduced, the lateral bulge caused by the narrowing of transverse diameter. Hypopharynx, tongue base large anteroposterior diameter will shrink, will be tired of water
