In order for a cochlear implant to function as designed, an audiologist must program it to meet the patient’s specific needs. MAPping is the term applied to the programming process. Initial MAPping includes setting up and turning on the unit after the surgical procedure. Essentially, MAPping helps to optimize the sound signals to the auditory nerve by adjusting the input to the electrodes on the implanted array.

Although different terminology, strategies, and capacities exist among the three FDA-approved models of implants, the process typically includes connection of the unit’s processor to the audiologist’s computer. Adjustments to thresholds (T-levels) to establish softest sound levels and comfortable level of loudness (C-levels) allow the patient to get the most out of the implant. Additional adjustments to stimulation rate or programming strategies can also be a part of the process.

After initial MAPping, follow-up MAPping is necessary to optimize the performance of the implant. These follow-up appointments are critical to initial stimulation and occur with greater frequency in the early stages after implanting but tend to stabilize over time and MAPping appointments become less frequent.

The Hearing Center of Medical Center Clinic performs initial and follow-up MAPping on CI devices for all three approved cochlear implant models manufactured by Cochlear Americas, Advanced Bionics, and Med-El.
