Efficacy Of Uvulopalatopharyngoplasty (UPPP)In Obstructive Sleep Apnoea

Abstract

Obstructive sleep apnoea (OSA) is the most common type of sleep apnoea and is caused by obstruction of the upper airway. It is characterized by repetitive pauses in breathing during sleep, despite the effort to breathe, and is usually associated with a reduction in blood oxygen saturation. These pauses in breathing, called apnoeas (literally, breath), typically last 20 to 40 seconds. OSA is commonly accompanied with snoring,& also associated with symptoms during the daytime. Symptoms may be present for years or even decades without identification, during which time the individual may become conditioned to the daytime sleepiness and fatigue associated with significant levels of sleep disturbance. Individuals who generally sleep alone are often unaware of the condition, without a regular bed-partner to notice and make them aware of their symptoms. The aetiology may be Dynamic cause due to increased soft tissue around the airway (sometimes due to obesity), and Fixed cause due to rigid structures like deviated septum, hypertrophied inferior turbinates,septal spurs, nasal polyps adenoid hypertrophy.
