Reserve Snails

Cochlear reserve (CR) is the degree of functional usefulness of the cochlea, which is determined by the difference between skin and air conductivity. RU is an important parameter for assessing the possibility of prosthetics and hearing improvement in case of hearing loss.

With hearing loss, the ear may lose its ability to conduct sound. This can happen due to various reasons such as infections, injuries, age-related changes or genetic disorders. If the ear cannot conduct sound, then the person can only hear low frequency sounds.

However, if there is sufficient cochlear reserve, hearing prosthetics and hearing-improving surgery can be performed to restore the ability to conduct sound in the ear. Hearing replacement includes the installation of hearing aids or the implantation of cochlear implants. Hearing-improving surgeries may include ossicular reconstruction, ossicular replacement, or eardrum repair.

A cochlear test is used to determine whether there is sufficient cochlear reserve. This test involves testing the cochlea's ability to conduct sound through air and bone. If the difference between these two ways of conducting sound is less than 20 dB, then this means that the cochlea's reserve is insufficient.

Cochlear reserve is the ability of the inner ear of the cochlea to perceive sound signals. It can be low or high, and is important when choosing the appropriate method for restoring hearing. A cochlea can be considered functional in the full sense when it copes with two tasks - bone and sound - equally well. At the same time, a violation of the reserve abilities of the cochlea makes functional hearing prosthetics available with its help - by implanting electrodes directly into the nerve centers of the cochlea. If, after surgery to compensate for hearing loss, residual hearing loss (preserved sensitivity of the cochlea) of varying degrees remains, the patient is covered by a guarantee for a lifetime free replacement of implants and all necessary equipment.

The concept of “cochlear reserve” (CR) is defined as the degree of the cochlea’s ability to transmit auditory signals to the human brain. Since the cochlea is an organ with limited ability to compensate for the loss of its functions, it is very important to take into account all factors, including the nature and degree of hearing loss, as well as the individual characteristics of the perception of sound by a sick person.

When using hearing aids for hearing loss, the cochlea is unable to accept some of them. Therefore, in order to understand how effective the proposed technologies will be, it is necessary to familiarize yourself with the type and degree of specifications. Many experts believe that with a hearing loss level of up to 50 dB, the chance of increasing this figure is 80-90%. If there is a significant deterioration in hearing, special prosthetic methods will help improve the situation!
