H65-H75: Diseases of middle ear and mastoid

H68: Eustachian salpingitis and obstruction

Eustachian salpingitis and obstruction refers to a group of conditions affecting the Eustachian tube, a small passage connecting the middle ear to the back of the throat. These conditions can be caused by numerous factors, such as allergies, sinus infections, or colds. Eustachian salpingitis is an inflammation of the Eustachian tube, while Eustachian obstruction refers to a physical blockage of the tube. Both conditions may result in symptoms such as ear pain, decreased hearing, and in severe cases, ear infections due to improper fluid drainage. Over time, if left untreated, these conditions could potentially lead to chronic middle ear problems, negatively impacting hearing and balance. The most commonly affected system is the auditory system, involving the ears and the related structures.
