543 OBSTRUCTIVE SLEEP APNEA (OSA) IS CHARACTER‐ IZED BY RECURRENT NARROWING AND OCCLUSION OF THE UPPER AIRWAY DURING SLEEP, RESULTING IN sleep fragmentation and intermittent hypoxemia.1 In the context of the current epidemic of obesity, it has been estimated that ap‐ proximately 17% of adults have mild or worse OSA, and 5.7% have moderate or worse OSA.2 It is associated with increased morbidity...

Upper airway measurements in nine infants considered to be at risk of upper airway insufficiency, six of whom presented after an apnoeic episode, were compared with measurements taken in two age groups of healthy infants. Paired, inspiratory and expiratory, lateral upper airway radiographs were obtained while the infants were awake and breathing quietly. The radiographs of all nine infants demo...

BACKGROUND Practice parameters for the treatment of obstructive sleep apnea syndrome (OSAS) in adults by surgical modification of the upper airway were first published in 1996 by the American Academy of Sleep Medicine (formerly ASDA). The following practice parameters update the previous practice parameters. These recommendations were reviewed and approved by the Board of Directors of the Ameri...

background croup, or acute laryngotracheobronchitis, is the most common cause of upper airway obstruction in children. objectives in this study, the efficacies of intramuscular and oral dexamethasone administration are compared for treatment of croup. patients and methods this is a single-blind randomized trial involving 68 children divided into two groups, the first group received 0.6 mg/kg in...

Marshall-Smith syndrome (MSS) is a rare clinical disorder, characterized by accelerated skeletal maturation, facial anomalies, failure to thrive and death in early infancy due to respiratory complications. We experienced the difficult airway case with MSS. A 4-year-old boy underwent tenosynovectomy for the snapping finger. Although his upper airway was diagnosed as almost normal on the fiber-op...

Sleep related disorders can have a drastic negative effect on the quality of life an individual. Obstructive sleep apnea (OSA) is well recognized condition that characterized by frequent short periods collapse upper airway, complete or partial obstruction airway during sleep, associated with snoring and brief arousals, resulting in disturbance deprivation. OSA reported as chronic disease affect...

STUDY OBJECTIVES The effectiveness of nasal continuous positive airway pressure (CPAP) in treating obstructive sleep apnea (OSA) is based on raising the intramural pressure above a critical collapsing pressure of the oropharyngeal airway. It is currently unclear whether CPAP delivered orally is also capable of raising pressure in the oropharynx above the critical collapse pressure. DESIGN We ...
