Hello. Welcome to 'Ask A Doctor". I have reviewed your daughter's history and here is my advice.
Unfortunately middle ear infections are common in children. Some, like Grace, have many in the early years of their lives and undergo surgery for tube placement, drum reconstruction, and
adenoid removal.
There are some diseases called
immunodeficiency disorders that predispose people to infections because their immune system is weak. One of these diseases may cause a person to have frequent skin infections while another makes the patient suffer with many respiratory infections.
Her history of abnormal tonsils, frequent middle ear infections(she is fortunate that her hearing is intact), abscessed teeth, and MRSA(where on her body did she have this infection?) makes me suspicious about an immunodeficiency.
I believe you should make an appointment for her to be seen by a pediatric allergist/immunologist or pediatric immunologist. These specialists are likely to be found at a university medical center. Be sure to take her medical records with you.
Final advice: she should avoid persons who smoke as this predisposes to ear infections and make sure she gets a yearly
flu shot.
Hope I have answered your query. If you have any further questions, I will be happy to help.
