목적: To investigate the correlation between the duration of cochlear implantation surgery and the findings observed in complicated cochlear CT scans. 방법:This study employed a cross-sectional design to evaluate the correlation between surgery duration and cochlear CT scan findings. A total of 45 cases meeting the inclusion criteria were selected from 203 patients who underwent cochlear implantation surgery at FCHM from 2009 to 2023. The CT scans of the cochlea were assessed using a 10-point system developed by Vaid et al. The duration of surgery, recorded complications, and imaging characteristics from the patients' medical histories were analyzed. Surgical complications were classified according to the Clavien-Dindo classification. 결과:Among the participants, 30 (66.7%) were male and 15 (33.3%) were female, with an average age of 9 10.6 years. The duration of surgery ranged from 70 to 150 (105.4 22.8) minutes. Complications were classified as follows: Grade I in 4 (8.9%), Grade II in 5 (11.1%), and Grade IIIb in 2 (4.4%). According to the Vaid scoring system, the estimated complexity of surgery was rated as follows: 0-3 in 29 patients (64.4%), 4-7 in 14 patients (31.1%), and 8 or higher in 2 patients (4.4%). Comparative analysis of CT findings with surgery duration indicated statistically significant correlations: a narrow facial nerve canal (p = 0.0001), identification of the cochlear base auditory bone connection (p = 0.003), and irregular positioning of the auditory canal (p = 0.0001). The surgery duration increased by: 23.3 5.9 minutes (p = 0.0001) with a narrow facial nerve canal, 8.1 3.5 minutes (p = 0.027) with an anterior facial nerve, 21 6.5 minutes (p = 0.003) when the cochlear base auditory bone connection was identified, 19.8 6.2 minutes (p = 0.003) with irregular positioning of the auditory canal. 결론:The duration of cochlear implantation surgery is prolonged, and complications may arise due to CT findings, including reduced air space in the cochlear duct, a narrow facial nerve canal, the identification of the cochlear base auditory bone connection, and irregular positioning of the auditory canal.
