Bilateral cochlear implantation in children with Noonan syndrome

Noonan syndrome is a mostly autosomal dominant inherited disorder, which can be accompanied by hearing disorders or deafness, coagulation disorders, combined heart defects and developmental disorders. We are reporting on two children with an established Noonan syndrome with a severe bilateral hearing loss of respectively 95 and 100 dB and proper findings in the CT/MRI of the petrous bone. After complete otologic and radiologic diagnostics, both children underwent bilateral cochlear implantation successfully. According to the authors’ knowledge, this is the first time that cochlear implant therapy is discussed in patients with Noonan syndrome.
