Snoring occurs when the ﬂow of air through a narrowed upper airway causes the surrounding tissues to vibrate, creating noises of varying pitch and volume. In the case of simple snoring, noisy breathing during sleep without airway obstruction, multiple factors can potentially be at work in creating the noise. These include overall body mass/obesity, enlargement of the tonsils and adenoid, the presence of nasal congestion from rhinitis and/or septal deviation and the prominence or bulkiness of the back of the tongue relative to the amount of space available for this structure. Treatment is usually medical, and may include medications for nasal issues or an appliance that is worn at night to pull the jaw and tongue forward during sleep. Surgery in the form of tonsillectomy and/or adenoidectomy or nasal surgery, may also be helpful in well selected patients.
