A new nasal acoustic reflection technique to estimate pharyngeal cross-sectional area during sleep.
The conventional acoustic reflection technique in which acoustic waves are launched through the mouth cannot be applied during sleep, nor can it be applied to the nasopharynx, which is the major site of occlusion in patients with obstructive sleep apnea syndrome. We propose a new technique of nasal acoustic reflection to measure pharyngeal cross-sectional areas including the nasopharynx. The ac...
متن کاملPharyngeal surgery and epidemiology in sleep apnea
Obstructive sleep apnea syndrome (OSAS) occurs frequently among adults and children. The fi rst-line treatments in adults are continuous positive airway pressure (CPAP) or mandibular retaining devices (MRDs), but the long-term effi cacy is only around 60%. Uvulopalatopharyngoplasty (UPPP) has been criticized for lack of effi cacy and a high degree of complications. In children the fi rst-line t...
متن کاملRelation between CT axial cross-sectional area of the oropharynx and obstructive sleep apnea syndrome in adults.
PURPOSE To look for correlation between obstructive sleep apnea syndrome (OSAS) and axial cross-sectional area of the narrowed oropharyngeal lumen. METHODS Thirty-six men with OSAS and 10 control subjects underwent polysomnography with registration of oxygen saturation and number of sleep apnea episodes and their duration. Nine of them underwent uvulopalatopharyngoplasty and repeated polysomn...
متن کاملAxial CT measurements of the cross-sectional area of the oropharynx in adults with obstructive sleep apnea syndrome.
PURPOSE To determine whether narrowing of the oropharynx increases during relaxation in patients with severe obstructive sleep apnea syndrome. MATERIALS The study included 23 adult men in whom polysomnography had established a diagnosis of obstructive sleep apnea syndrome. Subjects had an average of 53 episodes of sleep apnea per hour, with each episode lasting 40 seconds or more. Oxygen satu...
متن کاملEpiglottis cross-sectional area and oropharyngeal airway length in male and female obstructive sleep apnea patients
INTRODUCTION Obstructive sleep apnea (OSA) is a male-predominant condition, characterized by repeated upper-airway collapse with continued diaphragmatic efforts during sleep, and is accompanied by severe physiological consequences. Multiple morphological aspects, including epiglottis cross-sectional area (CSA) and oropharyngeal airway length (OPAL), can contribute to airway collapsibility in th...
