RESUMEN
Objective:To investigate the predictive value of temporal bone high-resolution CTï¼HRCTï¼ multiplanar reconstructionï¼MPRï¼ for cerebrospinal fluidï¼CSFï¼ gusher during cochlear implantation in patients with inner ear malformation. Methods:The clinical data of 33 patientsï¼36 earsï¼ with inner ear malformation who underwent cochlear implantation were retrospectively analyzed. The predictive value of HRCT for cerebrospinal fluid gusher during cochlear implantation was evaluated. Results:The width of the cochlear foramenï¼P=0.024, OR=1.735ï¼ and the diameter of the inner auditory meatusï¼P=0.022, OR=6.119ï¼ were independent risk factors for CSF gusher during cochlear implantation. The area under the curveï¼AUCï¼ of cochlear foramen width in predicting intraoperative gusher was 0.851, the sensitivity was 93.33%, and the specificity was 61.90%. The AUC of the upper and lower diameter of the internal auditory canal for predicting intraoperative gusher was 0.848, the sensitivity was 80.00%, and the specificity was 80.95%. The AUC of cochlear foramen width combined with the upper and lower diameters of the internal auditory meatus for predicting intraoperative gusher was 0.930, the sensitivity was 80.00%, and the specificity was 95.24%. Conclusion:Based on temporal bone HRCT, the prediction model of cochlear foramen width combined with the upper and lower diameter of the internal auditory canal has crucial predictive value for the "gusher" during cochlear implantation in patients with inner ear malformation.
