HelloWelcome to Chat Doctor Congratulations ! You have defeated your cancer. The side effects you mentioned are typical long term effects of treatment you received. The long-term effects of radiation depend on the technique of irradiation, the dose and the location that was irradiated. In the past typically 2 fields were given from lateral side to cover face and upper neck and a low anterior field to treat lower neck. So almost all normal tissue received radiotherapy and developed side effect. Eustachian tube is a connection between ear and hypopharynx. Dysfunction of this tube is common and can cause repeated ear infection. Although it is on and off problem; if there is sign of infection you need to take antibiotic. Change in climate can also help as you mentioned. Regards
