Clinical polysomnography in the evaluation of snoring and sleep-related breathing disorders

Abstract

The advent of laser-assisted uvulopalatoplasty has contributed to a recent increase in the number of patients who are evaluated for snoring and sleep-related breathing disorders. These disorders are often the result of compromised upper airway patency. They are characterized by respiratory disturbance during sleep as well as symptoms occurring during wakefulness. The consequences of sleep-related breathing disorders are significant because they are associated with an increased risk of cardiovascular illness and mortality. The evaluation of snoring and respiration during sleep involves the use of polysomnography, which is required to differentiate simple snoring from more serious sleep-related breathing disorders. Preoperative polysomnography is recommended for all laser-assisted uvulapalatoplasty candidates, and postoperative studies may be indicated to document treatment efficacy and for long-term follow-up.
