H65-H75: Diseases of middle ear and mastoid

H69: Other disorders of Eustachian tube

The group of conditions known as 'other disorders of the Eustachian tube' refers to any issues relating to the tube which connects the middle ear to the back of the throat. Its role is to equalize air pressure on either side of your eardrum, and when this tube does not work properly, it can lead to problems such as pain, hearing issues, or a sensation of fullness in the ear. Causes of Eustachian tube disorders can vary and include factors like allergies, infections, rapid altitude changes resulting in 'barotrauma', and congenital (present at birth) abnormalities. Symptoms can range from mild ear discomfort to severe pain, muffled hearing, or even balance problems. It's important to recognize that these conditions can evolve over time if not addressed, potentially leading to further complications such as chronic ear infections or middle ear fluid congestion. These disorders affect the auditory system.
