Sleep disordered breathing (SDB) is a spectrum of diseases that includes snoring, upper airway resistance syndrome, and obstructive sleep apnea (OSA). Snoring is caused by the vibration of the structures in the oral cavity and oropharynx—namely the soft palate, uvula, tonsils, base of the tongue, epiglottis, and pharyngeal walls. Snoring is considered a social nuisance and an objectionable social problem. It bothers the spouse more than the patient. Sleep disordered breathing encompasses simple snorers (patients who snore without excessive daytime somnolence and with a normal apnea-hypopnea index), upper airway resistance syndrome, UARS (patients with excessive daytime somnolence but have a normal apnea-hypopnea index), and obstructive sleep apnea (OSA) (patients who snore with both excessive daytime somnolence and an abnormal apnea-hypopnea index). Overall, these sleep disorders result in poor sleep quality, fragmented sleep, intermittent nighttime hypoxemia, reduced percentage of slow-wave sleep, and increased sympathetic overdrive. The results are daytime somnolence, morning headaches, poor concentration, loss of memory, frustration, depression, and even marital discord.
