A Prospective Study on Surgical Outcomes In Obstructive Sleep Apnoea? A Series of 40 Cases

Obstructive sleep apnea syndrome (OSAS) is characterised by repetitive sleep-related upper airway obstructions resulting in sleep fragmentation and decrease in blood oxygen saturation. It is seen approximately in 1-5% of adult men and in 1.2-2.5% of adult female [1, 2, 3]. Guilleminault, Eldridge, and Dement were the first to first sleep syndrome in 1973 with establishing one of the first sleep clinics in the world [4]. Polysomnography is the gold standard for the diagnosis of OSAS [5], providing information about the severity of OSAS and degree of sleep fragmentation but not the level of upper airway obstruction. The site of upper airway obstruction can be assessed by magnetic resonance imaging, computerised tomography, lateral Cephalometrics and nasopharyngoscopy [6-9]. A rational approach needs to be devised, by analysing both anatomical and physiological parameters for optimal management [10]. The purpose of the study is to compare surgical outcomes in patients with obstructive sleep apnoea.
