Remarks on qualification of patients for cochlear implantation
Journal Title: Polski Przegląd Otorynolaryngologiczny - Year 2016, Vol 5, Issue 1
Abstract
Over thirty years of progress in development of surgical techniques and cochlear implant technology led to a change in approach and extending of indications for qualifying patients to treatment of sensorineural hearing loss. Basic indications for cochlear implants include bilateral deafness, bilateral residual hearing or profound bilat-eral sensorineural hearing impairment as well as lack of acoustic gain from classic air conduction hearing aids af-ter a minimum of 5-6 months of use. Methods of subjective and objective hearing assessment are applied. Psycho-logical evaluation is aimed at assessing expectations of the patient/child’s parents, motivation, and intellect with regard to the presence of deficits that might pose difficulty in the course of further rehabilitation as well as accep-tance of this new type of stimulation. Speech and language evaluation takes into consideration the current level of speech development, articulation disorders related to hearing impairment, and the way to communicate with the environment. Final qualification requires imaging diagnostics of the head/ears (CT and/or MRI). Our surgi-cal experience allowed for implanting children with various congenital anomalies of the inner ear. Inflammation within the tympanic cavity and air-filled spaces of the mastoid process might require removal of inflammatory foci prior to surgery or selection of different surgical approach.
