Abstract

This is a cases series study of 49 patients with congenital malformations undergoing cochlear implantation at Ear-Nose and Throat hospital - Ho Chi Minh city from 2010 to 2024. Results: The average age at implantation was 5.1 ± 4.6 years old. There were 30.6% cases with inner ear malformations, 30.6% cases with cochlear nerve deficiency and 38.8% cases with combination of inner ear malformations and cochlear nerve deficiency. The most common inner ear anomaly noted were incomplete partition type 2 (26.5%) following by cochlear hypoplasia type 3 (16.4%) and enlarged vestibular aqueduct (10.3%). In the cochlear nerve deficiency group, the proportion of cochlear nerve hypoplasia was 42.9% and cochlear nerve aplasia was 26.5%. The electrode insertion was performed using the round window technique in 79.6% patients. The audiological outcomes based on CAP score was 4.9 ± 1.5 at 1 year post-operative. Conclusion: With meticulous evalution of imaging, appropriate choice of electrode and surgery approach, the cochlear implantation can be performed safely, successfully and efficiently in patients with congenital malformations.
