Objectives: This multicenter study evaluated the auditory performance and speech production outcomes of cochlear implantation in children with inner ear anomaly and compared the outcomes of patients with different kinds of malformation. Methods: Cochlear implantation was performed in 107 children with inner ear malformation at four tertiary academic centers. The categories of auditory performance (CAP) and speech intelligibility rating (SIR) scores were evaluated preoperatively and one year and two years postoperatively. Results: Types of inner ear malformation and their frequencies were: incomplete partition type-I, 19 (17.8) patients; incomplete partition type-II, 31 (29), common cavity, 17 (15.9), cochlear hypoplasia, 17 (15.9), and isolated enlarged vestibular aqueduct (isolated EVA), 23 (21.5) patients. EVA was the coexisting anomaly in 27(25.2) subjects. The median CAP and SIR scores improved significantly during the first two years after cochlear implantation in all groups (p-values <0.001 and < 0.001, respectively). No significant difference was seen in CAP and SIR scores of children with different inner ear malformations (p-value = 0.147 and 0.570, respectively) or in patients with isolated EVA compared to coexisting EVA (p-value = 0.538 and 0.075, respectively). Conclusion: The median CAP and SIR scores two years after surgery were 5 (Understanding of common phrases without lip-reading) IQR: 4�6, and 3 (Connected speech is intelligible to a listener who concentrates and lip-reads within a known context) IQR: 3�4, respectively. Auditory performance and speech production were significantly improved in all inner ear malformation patient groups, and no significant difference was observed between the scores of patients with different types of anomaly. © 2020 Elsevier B.V.
