ABSTRACT
This paper reports a clinical case that gives evidence of the possibility of cochlear implantation after liver transplantation. Patient K. aged 3 years 10 months was admitted to the Russian Research and Practical Centre of Audiology and Hearing Rehabilitation with the diagnosis of type IB glycogenosis after maternal liver transplantation associated with chronic neutropenia, chronic cutaneous and mucosal infection, partial symptomatic partial epilepsy, retarded psycho-motor development, and complaints of the absence of auditory response. The audiological examination provided materials for the diagnosis of grade IV bilateral sensorineural hearing loss tending toward deafness. Cochlear implantation recommended to the patient was performed on February 20, 2013 using the HiRes 90 K implant with the HiFocus Helix electrode (Advanced Bionics, USA). The surgical intervention and the postoperative period passed without complications. The speech processor was activated one month after surgery. The results of surdopedagogical testing gave evidence of successful rehabilitation promising the further improvement. It is concluded that immunosuppressive therapy is not an absolute contraindication for cochlear implantation, but this procedure requires detailed examination and thorough preparation for the forthcoming surgery.
