ABSTRACT
<p><b>OBJECTIVE</b>To investigate the related parameters of the temporal bone structure for determining the position of implanting electrode into the scala tympani in cochlear implantation surgery through the facial recess and epitympanum approach.</p><p><b>METHODS</b>In a surgical simulation experiment, 20 human temporal bones were studied and measured to determine the related parameters of the temporal bone structure.</p><p><b>RESULTS</b>The distance 5.91∓0.29 mm between the short process of the incus and the round window niche, 2.11∓0.18 mm between the stapes and the round window niche, 6.70∓0.19 mm between the facial nerve in the perpendicular paragraph and the round window niche, 2.22∓0.21 mm from the pyramidal eminence to the round window, and 2.16∓0.14 mm between the stapes and the round window. The minimal distance between the implanting electrode and the vestibular window was 2.12∓0.19 mm. The distance between the cochleariform process and the round window niche was 3.79∓0.17 mm. The position of the cochlear electrode array insertion into the second cochlear turn was 2.25∓0.13 mm under the stapes. The location of the cochlear electrode array insertion into the second cochlear turn was 2.28∓0.20 mm inferior to the pyramidal eminence.</p><p><b>CONCLUSION</b>These parameters provide a reference value to determine the different positions of cochlear electrode array insertion into the scale tympani in different patients.</p>
