Auditory brainstem implant technology and use: Auditory implants
Keywords:Brainstem implant technology, auditory implant, cochlea, cochlear aplasia, hearing loss
Cochlear implant (CI) technology is used in the treatment of deep sensorineural hearing loss (SNHL). However, an intact cochlea and an intact cochlear nerve are needed for CI applications. CI does not help in pathologies that may occur in these regions, and it is necessary to ensure the continuity of auditory conduction by direct stimulation of the cochlear nuclei. The method developed to ensure this auditory continuity is auditory brainstem implant (ABI) applications. In short, the ABI functions without the cochlea and the cochlear nerve. It does not need these structures. According to CI practices, postoperative gains are unfortunately not at the desired level. Auditory information can be helpful in lip-reading, although its benefits on speech perception are generally limited. In addition, ABI applications enable environmental sounds to be heard even if they are not fully perceived, and it is known to be beneficial on quality of life.
