Obstructive sleep apnea syndrome (OSAS) is characterised by repetitive sleep-related up-per 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 as-sessed by magnetic resonance imaging, com-puterised tomography, lateral Cephalomet-rics and nasopharyngoscopy [6-9]. A rational approach needs to be devised, by an-alysing both anatomical and physiological pa-rameters for optimal management [10]. The purpose of the study is to compare surgical out-comes in patients with obstructive sleep ap-noea.
