Abstract

Objective: To describe the size characteristics of normal and malformed cochleas on computed tomography in cochlear implant. Material and Methods: Descriptive study of the size of normal and malformed cochleas on preoperative imaging in cochlear implants. The inner ear was evaluated on CT and MRI, and the size of the cochlea was evaluated on high-resolution CT. Results: The study included 166 patients with 332 ears, including 170 ears with inner ear malformations. The group with normal inner ear had an average transverse diameter of the cochlear basal turn were 9,03±0,32mm. Cochlear hypoplasia and incomplete partition Type III had the smallest cochlear size with transverse diameters of the cochlear basal turn were 7,97±0.63mm and 7,99±0.5mm, respectively. Conclusion: Inner ear malformations have diverse cochlear shapes and sizes. Severe malformations such as labyrinthine aplasia, cochlear aplasia, and cochlear hypoplasia Type 1 have no indication for cochlear implant. For malformations that have indication for cochlear implant, depending on the type of malformation, it is necessary to choose an electrode suitable for the size and shape of the cochlea.
