Bilateral cochlear implantation in children with common cavity

Abstract Objective A child with severe sensorineural hearing loss due to congenital malformation of the inner ear may benefit from cochlear implantation. However, surgery is usually difficult for a surgeon due to anatomical variability; hearing benefit is uncertain; and there is a risk of complications. Patient and intervention We describe a case of a child with bilateral common cavity malformation (CCM) in which we performed bilateral cochlear implantation using transmastoid labyrinthotomy (TML) with a standard electrode. Main outcomes and results We observed a very good audiological results using Visual Reinforcement Audiometry and speech development after the implantaion. Conclusion TML is a simple procedure which is less time-consuming and which carries a lower risk of facial nerve damage.
