Cochlear implantation of a deaf blind patient with mitochondrial cytopathy

J Laryngol Otol. 1999 Apr;113(4):353-4. doi: 10.1017/s0022215100143956.


Genetic defects of the mitochondrial DNA often cause sensorineural hearing impairment, accompaniment by disorders of organs within the body. This case report describes cochlear implantation of a 33-year-old deaf blind female with mitochondrial cytopathy. The outcome was very successful, and vastly improved quality of life for this patient. Many cases of mitochondrial cytopathy cause progressive deafness; it is, therefore, likely that other patients with this unusual disorder will present for cochlear implant assessment.
