Abstract
We presented a series of patients with a mitochondrial DNA mutation who presented to our clinic with sudden bilateral sudden on chronic sensorineural hearing loss; these patients responded well to cochlear implantation. In cases of sudden sensorineural hearing loss-particularly when clinical features raise suspicion for an underlying mitochondrial disorder-genetic testing may offer valuable diagnostic insight and assist in guiding appropriate management strategies.
