A 6 year old boy with congenital hearing loss approached an ENT surgeon for cochlear implantation. TRUE regarding cochlear implants is:

Congenital malformations of the cochlea are not contraindications to cochlear implantation. Contraindications for Cochlear Implants: 1. Deafness caused by lesions of the acoustic nerve or the central auditory pathway 2. Active middle ear infections 3. Cochlear ossification that prevents electrode inseion 4. Tympanic membrane perforation Appropriate age for cochlear implantation is between 2-17 years. Bilateral severe-to-profound sensorineural hearing loss is the main criteria for implantation. The electrode is inseed through the round window into the scala tympani of the cochlea.
