Histopathology of Inner Ear Malformations: Important Considerations for Cochlear Implant Surgery

Histopathologic findings suggest that lateral wall electrodes may be preferable for many IEM cases to avoid damage to unprotected neural tissue. Electrode selection should be individualized based on the type of malformation, particularly considering compressed or shortened arrays in cases of cochlear hypoplasia. Neural tissue preservation despite bony malformation supports the potential for successful CI outcomes in IEM cases when appropriate surgical techniques and electrode choices are employed.
