Symptoms of Snoring

Snoring: Sleep apnoea (OSA), Upper airways resistance syndrome (UARS), Sleep Disordered Breathing (SDB)

Snoring is a sound produced by vibration of the soft tissues of the upper airway (ie. stertor) during sleep.Snoring is usually low in pitch and not musical. It is heard during inspiration (breathing in or inhaling), or is heard during both inspiration and expiration (taking a breathing out or exhaling). Occasional snoring is almost universal, while regular snoring is common.

Snoring is one of the symptoms of Sleep Disordered Breathing (SDB), a spectrum of breathing disturbances while asleep which includes: simple snoring (intermittent snoring, chronic heavy snoring), upper airways resistance syndrome (UARS) and obstructive sleep apnoea (OSA). Other symptoms may be associated with snoring such as disrupted sleep, arousals from sleep, apneas, daytime somnolence, chronic fatigue and impaired cognition.

How do we evaluate snoring?

People with snoring are initially evaluated by taking a thorough medical history and by performing an examination of the upper airway, including endoscopy. Standard endoscopy of the throat is called laryngoscopy, in which an endoscope (a slim tube with a camera on the end)is passed through the noseusing local anaesthetic to examine the airway. Additional investigations such as CT scanning, and/or or a sleep study, may be required.
