Doc is sending me too ent dept for hearing test i am slightly dear in left ear and ringing in left side of my head what can i expect from app?

Hearing test, exam: Hopefully you will get a thorough head and neck exam including the ears and a hearing test. The test should be able to tell if the loss is by the nerve, the drum and hearing bones, or both. If there is a major difference from the other ear additional testing may be necessary with possible mri. Surgery for conductive loss or hearing aid for nerve loss might be recommended.
