Often the tinnitus is only in one ear. In some of these situations, the tinnitus can be treated surgically, and thus a visit to an otologist (a physician specializing in the ear) is advisable. Sensorineural tinnitus can have many causes (e.g. noise, medications, head injury, infections, and aging).
Many causes - almost everything that can go wrong with our ears can produce tinnitus as a symptom! Perhaps as simple as wax against the eardrum, or as serious as a tumour on the hearing nerve. Otosclerosis (fixation of the tiny stirrup bone in the middle ear) can produce tinnitus; so can Meniere's disease. A major cause of tinnitus is EXPOSURE TO EXCESSIVE NOISE, e.g. chain saws, machinery, rock concerts.
