During cochlear implantation, doctors create a flap in the scalp and insert an electrode within the ear. Several risks are associated with the traditional procedure including flap breakdown, electrode misplacement, infection, facial nerve damage and meningitis. However, minimally invasive cochlear implantation (MICI) is designed to avoid a large scalp flap. Rather, doctors make a three- to four-centimeter incision and create a pocket for the implant.

In San Antonio, University of Texas researchers reviewed data on 176 patients who underwent MICI. They found the total complication rate to be just under 13 percent. Complications included device failure, facial nerve paralysis, a change in taste and dizziness or balance problems.

According to researchers, the complication rate for MICI is no higher than that reported for the traditional procedure. The minimally invasive procedure decreases tissue trauma, allowing for immediate programming and use of the device following the procedure. Researchers suggest MICI as the preferred option for patients undergoing this sort of procedure.
