Abstract：Objective To investigate the application value of preoperative multimodal three-dimensional reconstruction in microvascular decompression(MVD)via the retrosigmoid approach for treating cranial nerve disorders.Methods The clinical data of 64 patients treated with MVD were analyzed retrospectively,including 33 cases of trigeminal neuralgia and 31 of hemifacial spasm.According to whether preoperative multimodal 3D reconstruction technology was used,the patients were divided into reconstruction group(n=34)and control group(n=30).And the accuracy of keyhole(transverse sinus-sigmoid sinus junction)positioning,the determination rate of offending vessels,the bone window area,operative time,surgical efficacy and complications were compared between the two groups.Results The accuracy rates of key holes in the reconstruction group and the control group was 91.18%and 70.00%,the determination rate of offending vessels 94.12%and 83.33%,the operative time(175.41±27.83)min and(191.80±26.00)min,and the bone window area(6.32±0.40)cm2 and(7.48±0.478)cm2 respectively There was a statistically significant difference between the two groups(P＜0.05).There was no significant difference in the incidence of complications and surgical efficacy between the two groups(P＞0.05).Conclusion The preoperative multimodal three-dimensional reconstruction may have a certain application potential in MVD via retrosigmoid approach in the treatment of cranial nerve diseases.
