dc.description.abstract | Purpose: in this study, we aimed to introduce the facial nerve as a new anatomical landmark which can be used in ossified cochleas during cochlear implantation. We also set out to define a safe line to preserve the internal auditory canal (IAC) while drilling the basal turn of the cochlea. Methods: Thirty patients who had temporal computed tomography (CT) were studied. the distances from the facial nerve and the round window to the IAC, carotid artery, and jugular bulb were measured in the reformatted CT images. We have created a line in the direction of the stapedial tendon from the round window to the IAC and called it ROWIAC (Round window–IAC) line. We have investigated whether this line intersects the IAC and measured the distances from this line to the IAC. Results: Fifty-four temporal CT scans were included to the study. the mean distances from the facial nerve to the IAC, carotid artery, and jugular bulb were 8.8 ± 0.9, 15.0 ± 2.0, and 12.2 ± 2.9 mm, respectively. the mean distances from the round window to these structures were 3.8 ± 0.7, 9.4 ± 2.2, and 8.3 ± 2.9 mm, respectively. ROWIAC line did not intersect the IAC in any of the patients. the mean distance between this line and the IAC was 0.8 ± 0.4 mm. Conclusion: We propose that facial nerve and ROWIAC line can be used as potential landmarks during cochlear implantation in ossified cochleas to protect the adjacent neurovascular structures. © 2020, Springer-Verlag GmbH Germany, part of Springer Nature. | en_US |
