Nose, Throat & Sinuses

See how air flows through the nose and throat and exactly what each condition changes — in interactive 3D with a live airflow trace — then find care.

Conditions in this section

• Sinusitis — The air-filled sinuses around the nose become inflamed and blocked — causing facial pain and a stuffy nose.
• Allergic Rhinitis (Hay Fever) — The nose over-reacts to allergens like dust or pollen — causing sneezing, itching and a runny, blocked nose.
• Common Cold — A mild viral infection of the nose and throat — very common, self-limiting, and eased with simple care.
• Tonsillitis — The tonsils at the back of the throat become infected and swollen — a sore throat that is common in children.
• Sore Throat (Pharyngitis) — Inflammation of the throat causing pain, especially on swallowing — usually a mild, self-limiting viral illness.
• Snoring & Sleep Apnea — The throat repeatedly narrows or collapses during sleep, briefly stopping breathing — treatable, and important for health.
