Tinnitus, or ringing in the ear, can have various triggers and occur at any age, most commonly after the age of 50. In most cases, tinnitus is difficult to detect as only certain types of tinnitus can be measured. In order to diagnose this condition, the patient must visit an ear, nose and throat specialist and undergo various hearing tests to find the root cause.
If the patient perceives a rhythmic pulsing noise in one or both ears, which tends to be synced with their heartbeat, they may be suffering from pulsatile tinnitus, also known as pulse synchronous. If only the patient hears the noises, they may be suffering from subjective tinnitus. The majority of cases of tinnitus are subjective. Tthe rarest form of tinnitus is objective tinnitus and it is a condition usually caused by disorders affecting the blood vessels (vascular system) or muscles (muscular system).
As there are different types of tinnitus, and each type can have many triggers, it can a difficult condition to diagnose. Consult an ENT speacialist if the ringing in the ears lasts longer than two days.
Even if an initial diagnosis has already been given by a physician, it is key to consult an ENT specialist for a more definitive diagnosis. To be able to establish a diagnosis and the best treatment for the patient, a comprehensive examination takes place at the ENT doctor, such as an ear microscopy, hearing tests and special tinnitus tests.
In order to determine the hearing threshold, it is important to rule out other possible causes of tinnitus, such as ear diseases (e.g. an ear canal infection) or a plug of earwax .
When sounds hit the ear, the hair cells in the inner ear contract. The otoacoustic emission test (OAE) measures hair cell function in the inner ear.
To perform this test, microphones are placed in the external auditory canal. These highly sensitive microphones are able to register particularly quiet sounds, allowing the doctor to observe the various processes occuring in the inner ear in detail, including Spontaneous and evoked otoacoustic emissions.
Incidentally, this test is also used when screening the hearing of newborns and infants or for early detection of noise-induced hearing damage in occupational medicine.
BERA (Brainstem Evoked Response Audiometry) is another hearing examination commonly used to diagnose tinnitus. This examination tests the nerve reactions in the brain that take place during the processing of auditory stimuli. The examination of these early auditory evoked potentials (FEAP) is painless.
To perform this test, three to four electrodes are placed around the head to measure what happens in certain areas of the brain when a sound is processed. This can tell us a lot about the functionality of the auditory nerve, the auditory pathway and can help exclude an acoustic neuroma, a type of non-cancerous (benign) brain tumour that can trigger tinnitus.
Tinnitus sound therapy is a treatment that matches the frequency of your tinnitus tone. Since there is no way to objectively measure the frequency, the patient must "hear" for themselves when the frequency played through the headphones by the ENT doctor matches to their tinnitinus tone.
Once the ringing in the ears is superimposed by a tone, the ENT doctor can determine the frequency of the tinnitus condition.
Depending on the results of the initial hearing tests described above, ENT doctors may perform additional tests:
A tinnitus sick leave is at the discretion of the doctor. The duration of a tinnitus sick leave can depend on what triggered the condition in the first place. If the trigger is stress, taking sick leave may be a viable option. Oftentimes, taking a break can help the tinnitus symptoms subside significantly or disappear altogether. However, if taking sick leave only removes all distractions and enhances the perception of disturbing sounds, it may be best to discuss other options with your doctor.
