The treatment of Eustachian Tube Dysfunction can be either treating the cause or the effect, can be medical or surgical, temporary or permanent and involve children or adults.  Cortico steroid nose sprays, antibiotics and even oral steroids are sometimes used.  Draining of the middle ear with, or without insertion of grommets can assist.  The adenoidectomy is a very important surgical procedure in children.  As the child gets older or in Adults, a Balloon Eustachian Tube Dilatation is often helpful.  If there is a cholesteatoma, surgery focused directly on the nature and extent of the cholesteatoma is used.  One might also have to patch the ear drum and what is important also in children is that time is also a healer with, or without using a hearing aid as the mucous in the middle ear can drain down the Eustachian Tube to the back of the nose spontaneously.
