Nose

Postnasal drip refers to mucus draining from the nose back into the throat. This may be caused by allergies, infections, or other inflammatory conditions of the nose. It is usually treated medically, with nasal sprays or oral allergy medications (or antibiotics when an infection is found to be the cause).

Obstructive sleep apnea is a condition in which the airway becomes blocked during sleep, causing the patient to stop breathing for brief periods of time. Sleep apnea may lead to poor sleep and fatigue and over time may contribute to heart and lung failure and even death, if severe and left untreated.

Snoring is a condition in which the airway becomes blocked or may vibrate during sleep, causing the patient to produce sound. Snoring may be associated with sleep apnea which may lead to poor sleep and fatigue and over time may contribute to heart and lung failure and even death, if severe and left untreated.

The turbinates are shelves of tissue along the sides of the inside of the nose. They are responsible for humidifying inspired air and moisturizing the nose. They also sense the flow of air through the nose. Turbinates may be enlarged due to bony overgrowth or inflammation and swelling of the lining.
