Cochlear implants are an amazing technology for the rehabilitation of patients with profound sensorineural hearing loss. Since its development, several advances in cochlear implant itself, in the surgical technique, and in the processor and software of the implant have allowed the expansion of the criteria for patient selection. In the last 15 years, new strategies for hearing preservation have been developed and improved, with the purpose of combining electrical and acoustic stimulation for patients with residual hearing in low frequencies who do not have a satisfactory hearing level with the conventional hearing aids. Electroacoustic stimulation can improve the hearing of patients with partial deafness and provide then more benefits than electrical stimulation alone, such as better speech discrimination in silence and in noisy environments, and better musical perception. Both the surgical technique used and the type of electrode of the cochlear implant are essential to obtain good hearing preservation levels. Many other aspects such as the best inner ear approach, perioperative drugs and details of the surgical technique are still being discussed in the literature and many recent articles were published. This manuscript aims to review the concepts of the electroacoustic stimulation and update the reader in this topic.
