What tests are needed for neurological tinnitus

The so-called neurogenic tinnitus, the patient may have a preconceived idea that he has no other problems, and the tinnitus has been going on for a long time and he does not pay attention to it. If the patient feels that it is abnormal and serious, he does not know what to do. For tinnitus patients who come to the hospital and want to seek further help, the most important thing is to do audiological examinations, including pure tone audiometry, sound conductance impedance, and even electrical response activity to evaluate whether there is any problem with the auditory pathway.

If there is a problem, an MRI of the brain is done, and if it is caused by other reasons, various tests are sometimes done. However, the overall situation should be based on the specific situation of the patient, and the overall evaluation should be carried out in the hospital, because sometimes tinnitus is really not an ear disease, but is caused by other reasons. So tinnitus can neither be taken too seriously nor too lightly.

Tinnitus can be examined accordingly according to its situation: 1. The cardiovascular system and endocrine system of internal medicine, such as hyperthyroidism and diabetes, will have a certain impact on tinnitus, so the examination is actually open, not that tinnitus is only for tinnitus examination; 2. Otolaryngology can do tinnitus matching, that is, in the audiometric room, the sound of the patient's tinnitus is similar to what kind of tinnitus sounds, so as to infer which part of the cochlea of the ear has a problem, which is a relatively unique examination in the otology. But when it comes to tinnitus, it will involve an open examination, depending on the patient's condition.

Nervous tinnitus is one of the common clinical conditions in otolaryngology, and its examination methods are mainly divided into laboratory and other examination methods.

The first is a general general examination, including blood pressure, blood glucose, blood lipids, blood, kidney function, thyroid function, etc., should be carried out in detail to rule out tinnitus caused by systemic diseases or other diseases.

The second examination is the audiological examination report, and the electrical audiometry acoustic impedance test, otoacoustic emission, electrical response audiometry, etc. should be systematically examined, and the results of these examinations can be carefully analyzed to make a preliminary judgment on the nature of the tinnitus and the location of the lesion.

The third is the examination of vestibular function, which can help to make an auxiliary diagnosis of tinnitus.

The fourth is imaging tests, including CT scans or magnetic resonance imaging of the ears, which can help to identify the location of tinnitus lesions.

The fifth is the objective measurement of tinnitus, including tinnitus loudness matching, masking test and residual celery brigade inhibition test, etc., which is mainly to objectively determine the behavior of tinnitus itself.

Analysis: The examination of neurological tinnitus is divided into 7 steps. The first step is a general general examination to understand the condition of the whole body system such as cardiovascular and endocrine.

The second step is a neurological examination to help check for diseases of the central nervous system. The third step is a special examination of the otolaryngology, routine examination of the head and neck of the ear, nose and throat, pay attention to whether there are space-occupying lesions in the nasopharynx, the opening of the eustachian tube, etc., and can also check whether there is pulsatile tinnitus, understand whether there is abnormal pulse of blood vessels, and the effect of compression of neck arteries and veins on tinnitus. The fourth step is a routine examination of auditory function, including electrical audiometry, acoustic impedance, otoacoustic emissions, auditory brainstem responses, etc.

The fifth step is vestibular function examination, including vestibular myogenic evoked potentials, cold and heat tests, rotor tests, dynamic balance function, coordination tests, etc. The 6th step is the psychoacoustic examination of tinnitus, including the location, tone, loudness of the tinnitus, etc. The seventh step is imaging examination, including CT, magnetic resonance, etc., to rule out congenital malformations of the ear, space-occupying lesions, etc.

Diagnosis of neurogenic tinnitus requires an otolaryngology examination, audiological tests, and imaging tests.

Otorhinolaryngology examination.

1.A systematic and comprehensive otolaryngological examination can find lesions in the ear, nose, pharynx and other parts, which is helpful to preliminarily judge the degree and ** of tinnitus.

2.Including external ear examination, eustachian tube examination, hearing examination, vestibular examination, external nasal and nasal examination, nasal function examination, nasal endoscopy, oropharyngeal examination, laryngeal examination, etc.

Audiology test.

1.Audiology tests are extremely important in the diagnosis of tinnitus. It can measure the function of the auditory system, the degree of hearing impairment, the location of the lesion, etc.

2.These include pure-tone audiometry, acoustic impedance audiometry, tinnitus tone and loudness matching testing, tinnitus after-effect suppression and minimal masking level testing, and other audiology and electrophysiology tests.

Imaging tests.

If the doctor suspects that the local or systemic disease is related to tinnitus, CT and magnetic resonance imaging may be selected to help diagnose the lesion and determine the location of the lesion.

1. Routine ear examination: Ear endoscopy to check whether there are abnormalities in the external auditory canal and tympanic membrane.

2. Audiological examination: pure tone audiometry, acoustic impedance, tinnitus tone and loudness matching detection, tinnitus after-effect suppression and minimum masking level detection, and other audiology and electrophysiological examinations.

3. Vestibular function test: When the patient has tinnitus and vertigo, the doctor may perform this examination to judge the wrong vestibular lesion.

5. Imaging examination: CT and MRI of the inner ear, usually doctors will only take this examination when considering neoplastic lesions.
