Preservation of Hearing in Cochlear Implant Surgery: Advantages of Combined Electrical and Acoustical Speech Processing

Objectives/Hypothesis: This study documents the importance of preserving residual low‐frequency acoustic hearing as those with more residual hearing are selected for cochlear implantation. Surgical strategies used for hearing preservation with a short hybrid cochlear implant are outlined. The benefits of preserved residual low‐frequency hearing, improved word understanding in noise, and music appreciation are described.
