sinus drainage

Mucus leaving cavities

Sinus drainage is the flow of mucus from the sinuses—the air-filled cavities in the skull around the nose and eyes.

The term usually appears in medical contexts describing symptoms: The doctor asked about sinus drainage.

When sinuses become inflamed or infected, drainage increases and may run down the back of the throat (postnasal drip) or out the nose.
