Hello Welcome in H.C.M. I have gone through your query regarding eustachian tube dysfunction and it s treatment. Before making effective plan for treatment of eustachian tube dysfunction it is necessary to find out the real pathology behind it. The various factors responsible for recurrent eustachian tube dysfunction are- 1- Chronic sinusitis. 2- Nasal polyp. 3- Adenoidal hypertrophy. 4- Chronic tonsillitis. 5- Neoplasm of nasopharynx. All above diseases are well known for giving recurrent infection to nasopharynx so if any of above are there that should be treated first and than after eustachian tube will start doing functions well automatically. Secondarly the causative agent for infection should be identifyed and antibiotic should be adviced according to culture and sensitivity report. After taking care of all above one should proceed to treat eustachian tube dysfunction as- 1- Antibiotic (as per recmondation of culture report). 2- Mucolytic and decongestant. 3- Anti histaminic. 4- Steam inhalation. 5- Steroids. Most of the cases are responding well by above treatment but unforunately if there is no satisfactory response than one should proceed for MYRINGOTOMY and GROMMET IMPLANTATION over ear drum. I think above answers your query. Regards.
