which essential oils safe for ear?

How can I best safely use essential oils that may help relax inner ear muscles without getting it in my ear? Which ones are best for ear issues such as tinnitus with hyperacusis, ear pain? I have taken medications that lessened the hyperacusis, by relaxing my inner ear muscles, but because they're toxic, I don't take them anymore. Because I can only find so many fresh herbs, I am not wanting to try ingesting new herbs unless its a seasoning plant or something else sold completely fresh. I've read tea tree oil placed on a cotton ball in the ear can rid an ear infection.
