[The cochlear implantation in patients with syndromic deafness. Clinical examples].

The only method that allows patients with bilateral congenital deafness to gain hearing is the cochlear implantation. The malformations of the tympanic cavity structures, an abnormal course of the facial nerve canal lead to technical difficulties during the surgical stage of cochlear implantation. The navigation equipment, monitoring of the facial nerve makes it easier to find anatomical structures, as well as to avoid injuries.
