Ct Evaluation Of Obstructive Sleep Apnea And Its Correlation With Poly Somnography

Abstract

Obstructive sleep apnea (OSA) syndrome is a common newlinedisorder affecting at least 2 to 4% of the adult population. OSA newline(using the definition of 5 or more events/ hour) affects almost 1 newlinebillion people globally, with 425 million adults aged 30-69 years newlinehaving moderate to severe OSA (15 or more events/h). Repetitive newlinecessation of breathing during sleep due to collapse of the upper newlineairway causes signs, symptoms and consequences such as increased newlinerisk of cardiovascular disease [1]. newlineThe risk factors categorized as anatomic factors includes newlineMicrognathia, retrognathia, Facial elongation, Mandibular newlinehypoplasia, Adenoid and tonsillar hypertrophy, Inferior newlinedisplacement of the hyoid; Non anatomic factors includes Central newlinefat distribution, Obesity, Advanced age, Male gender, Supine newlinesleeping position, Pregnancy and addition factor includes alcohol newlineuse, smoking, Use of sedatives and hypnotics associated medical newlinedisorder includes Endocrine disorders Neurological disorders, newlinePrader Willi syndrome, Down Syndrome, Congestive heart failure, newlineAtrial fibrillation ,Obesity hypoventilation syndrome (OHS) newline newlineThe purpose of this study to assess computed tomographic newlinefindings combined with polysomnogr aphy for better visualization of newlineanatomic data related to obstructive sleep apnea and their newlineassociations with the polysomnography data and patient newlinecharacteristics CT/MRI finding newline
