Hearing Impairment

Hearing loss occurs either as a result of damage to parts of the outer and middle ear, or if the parts of the inner ear are damaged, so the following diagnoses are distinguished:

  1. Conductive Hearing Loss

    With conductive hearing loss, changes do not affect the structure of the inner ear and the auditory nerve, but affect the region of the tympanic membrane and middle ear. For example, impairment of mobility in the system of auditory ossicles or extensive trauma of the tympanic membrane.Learn More

  2. Sensorineural hearing loss

    With sensorineural hearing loss, hair cells in the cochlea or auditory nerve are damaged, which is less common. With this kind of hearing impairment in young children, sound vibrations can not be converted into electrical signals, which leads to the impossibility of recognizing sounds by the brain.Learn More

  3. Mixed hearing loss

    Mixed deafness is a combination of sensorineural and conductive hearing loss. It occurs with problems of the inner, outer or middle ear.Learn More
