Snorer's Uvula. Snorers traumatise their own uvula (the hanging down thing in the back of the mouth)

Here's a picture of a swollen lower uvula in a chronic snorer. See the demarcation line about 2/3 of the way up? The uvula is the main site of snoring sound production, although rarely the cause, as that's narrowing of the retro lingual space. However laser palatoplasty can be very helpful in turning down the volume of snoring

down.
