User:Mr. Ibrahem/Eustachian tube dysfunction

Eustachian tube dysfunction (ETD) is defined as pressure abnormalities in the middle ear which result in symptoms. Symptoms often include fullness, popping, or pain in the ear. Other symptoms may include ringing or muffled hearing.

Causes may include an upper respiratory tract infection, allergic rhinitis, pressure changes, or recent weight loss. Diagnosis is based on symptoms and examination. It is divided into three types: dilatory, were the tube dose not open; baro-challenged induced, which occurs with pressure changes; and patulous, were the tube dose not close properly. It is also divided into acute and chronic depending on if it last less or more than 3 months.

Treatment depends on the probable cause. This may involved addressing GERD, avoiding allergens, removing enlarged tonsils, or dilating the tube. It affects about 1% of adults. Under 20, males are more likely to be affected, while in older ages, females are more likely to be affected.
