Hearing impairment is the inability to hear, which leads to hearing loss. If a person has a hearing disability, the hearing loss can be helped with the use of hearing aids. Therefore, It will be necessary to determine the ability to hear and locate the lesion in the outer, middle, inner, or central corner by conducting various tests and using audiometric equipment. Hearing rehabilitation includes instruction in lip-reading, sign language, prevention, and special care.
The following diagnostic and rehabilitation services are provided in the hearing assessment section:
  • Hearing assessment (audiometry and tympanometry)
  • Hearing aid consultation
  • Electrophysiological tests including ABR, OAE, and R
  • Body Balance Assessments
What is dizziness?
Dizziness is a condition in which a person believes that objects or, in particular, that space revolves around them. Dizziness can indicate a particular illness or weakness in the body. (Dizziness, blurring, and darkening of the eyes should be taken seriously and the doctor should be consulted as it could be dangerous.)
Neck vertigo
Cervical vertigo is dizziness that occurs due to posture and the specific position of the neck. For example, the type of dizziness that occurs when turning the head left and right while the patient is sitting straight on a chair. Another definition of vertigo is "dizziness that occurs due to neck disorders."
The prevalence of this type of vertigo is not entirely clear, however, 20 to 58 percent of patients with whiplash injuries reported dizziness, dizziness, and imbalance. In this form of vertigo, there seem to be no auditory symptoms, although ear pain is common. There is no consensus on the best way to diagnose this type of vertigo. The most important argument is that there should be nystagmus that does not change with the change of gravity, but changes with the movement or different position of the head.
There are several theories about the mechanism of this vertigo:
  • Vascular problem: compression, spasm, and dissection
  • Abnormal neck proprioceptive input
  • Pressure on the neck spinal cord
  • Cerebrospinal fluid (CSF) leakage
  • Barré – Liéou “syndrome”
  • Problem with C1-C2 vertebrae
  • Cervicogenic migraine
Diagnosis: The most common age of this type of vertigo is between 30 and 50 years old and is more common in women. Neck pain should typically be present, but the pain in the neck is not reported when it is caused by cervical vascular disorder. In certain cases, buzzing and low-frequency hearing loss have also been reported.
Diagnostic criteria usually include the following:
  • Elimination of other causes: ear disease, brain disease, migraine
  • Nystagmus with head rotation
  • Neck MRI
  • Neck inflexibility
  • Symptoms after a neck injury
Treatment for this condition usually includes a combination of medication, rehabilitation, and postural exercise, and correction of sitting posture and neck pressure once the cause has been identified.

Neonatal hearing loss
Hearing loss or deafness is the most common congenital disorder in infants and almost 
20 deaf children are born every day in our country. Hearing loss has a major impact on the development of speech skills, the acquisition of emotional and cognitive social skills during growth, and, as a result, creates occupational, social, and psychological challenges for a deaf person when joining the society.
According to the Global Guideline (Clinical Principles) for early intervention, which has been developed in our country. If a hearing loss is diagnosed in a child, rehabilitation and education procedures should be conducted in the shortest time possible with the best available quality.
