Background:One of the mechanisms that cause tip fold-over is a misalignment between the electrode array’s coiling direction and the cochlea’s curving direction.Objectives:We reviewed surgical videos and computed tomography (CT) datasets of the patients who underwent cochlear implantation procedures from January 2010 to December 2021, paying particular attention to the cochlea’s orientation in the surgeon’s microscopic view.Methods:CT dataset and video recordings were analyzed to measure the “slope angle,” which is the angle between the cochlea’s coiling plane and the horizontal plane.Results:There were 220 cases that met the criteria and completed the analysis. The mean slope angle was 12.1±9.5, with a minimum of− 9.4 and maximum of 44.6. However, each surgeon had a favored slope angle range.Conclusion:Understanding the slope angle and making an effort to reduce the chance of misalignment during electrode insertion may help prevent tip fold-over of slim perimodiolar electrode arrays.
