[Abstract] Objective: To evaluate the value of magnetic resonance imaging (MRI) in congenital inner ear malformations before cochlear implantation surgery.Materials and Methods: MRI of fifty-six children with inner ear malformations who were younger than 3 years old were retrospectively analyzed according to the latest classification criteria.Results: Of all 56 cases (107 ears) inner ear malformations, there were cochlear malformations in 56 ears, vestibular malformations in 68 ears, semicircular canal malformations in 71 ears, large endolymphatic duct and sac syndrome in 37 ears, internal auditory canal malformations in 50 ears, cochlear nerve dysplasia in 58 ears.Conclusion: The congenital malformations of inner ear can be well demonstrated by MRI. Therefore it should be used routinely before cochlear implantation.
