ASSESSMENT OF ACCURACY OF PREOPERATIVE HIGH RESOLUTION COMPUTED TOMOGRAPHY TEMPORAL MEASUREMENTS IN PREDICITNG THE VISUALISATION OF ROUND WINDOW AS VIEWED THROUGH FACIAL RECESS

Abstract

For cochlear implantation to be successful the clear visualization of the round window is prime requisite for the surgeon in placing the electrode into the cochlea either by cochleostomy or round window membrane approach However due to variations in position of round window the visibility of the round window is difficult and could result in failure of the surgery hence we undertook the study to determine the accuracy of preoperative HRCT temporal bone measurements in predicting the visualization of round window as viewed through facial recess during cochlear implant surgery in children newline
