The current cochlear implant (CI) criteria for patients with bilateral sensor neural hearing loss associated with other commitments have expanded, as shown in national and international studies that show the benefits of the CI for this population. The objective of this study is to describe the development of auditory and language skills in children with cochlear implants who have variables that may affect the expected performance of these skills. This study shows the development of language and hearing skills in three specific cases: auditory neuropathy spectrum disorder, agenesis of the corpus callous, and cerebral palsy. Patients in this study had an effective and gradual improvement in hearing and language skills, thereby proving the effectiveness of the CI when it is associated with family involvement, regular speech therapy, and partnership with the cochlear implant programming team. This study shows that it is possible to obtain effective results with cochlear implants, even when patients have other conditions in their medical history.
