Abstract
Obstructive sleep apnea (OSA) is a disorder caused by repetitive occlusion of the upper airway during sleep. It can be treated by multiple therapeutical options including medical, behavioral and surgical.
Nasal continuous positive airway pressure (CPAP) is the treatment of choice of OSA however; the compliance of the patients is very low. Surgery is used as an alternative to CPAP. There are many surgical modalities in the treatment of OSA but neither one of them have accomplished complete success. The success rate of uvulopalatopharyngoplasty which is the most famous operation in the treatment of snoring and obstructive sleep apnea does not exceed 40%.
In this study we aim at highlighting the different causes of failure of the different treatment modalities of OSA.
