Can tinnitus in one ear with no hearing loss be fixed?

Wombat,: Asymmetrical tinnitus is not as frequent as the bilateral variety. It should be checked by a neurologist.

Depends on the cause: There are many different things that cause tinnitus. I recommend you see an otolaryngologist for a full evaluation. Be prepared with your medical ; surgical history and write down ahead of time all the medications (even herbals ; vitamins) that you're taking. Plan to discuss when your problem started and the quality of the tinnitus (high-pitched? Rushing sound? Continuous? Rhythmic? Etc...).
