Tinnitus is strongly associated with hearing loss and in most cases, audiologists believe that tinnitus stems from damage to the outer hair cells of the cochlea. These sensory receptor cells can become damaged leading to less auditory stimulation reaching the brain. This lack of auditory stimulation leads the brain to create sound ‘tinnitus’ to fill in the ‘empty space’.
Other known causes of tinnitus include medication, stress, muscle tension, central pathology, and noise exposure. When tinnitus is associated with medication, it often times diminishes when the medication is stopped. It should also be noted that medication inducted tinnitus can worsen if the medication dosage is increased. Some of the medications that can cause tinnitus include certain antibiotics, anti-depressants, aspirin, quinine, some forms of chemo therapy, quinine, and diuretics. When stress and muscle tension are the cause of tinnitus, treating those conditions will often times lead to a reduction in tinnitus.
Tinnitus can further be classified in two different ways, subjective tinnitus, the most common form of tinnitus, and objective tinnitus, a rarer form of tinnitus.
Subjective tinnitus can only be heard by the individual perceiving it, while objective tinnitus can also be heard by a doctor during an otologic evaluation. The cause of objective tinnitus can be vascular in nature. In cases like this, vascular flow is audible and would warrant further medical work up.
Objective tinnitus may also result from middle ear myoclonus. Middle ear myoclonus is potentially related to the tensor tympani or the stapedius tendon.
The case history is a very important part of the evaluation to attempt to diagnose the cause of a patient’s tinnitus. It is necessary to clearly state symptoms and characteristics of tinnitus during this otologic evaluation. The more information that your doctor obtains, the more likely they will be to establish a correct diagnosis. Some of the questions you will encounter could include the following:
Once all information has been collected and assessed, you doctor will hopefully be able to identify the specific underlying cause of tinnitus and attempt to establish a treatment plan.
