The purpose of this study is to compare and evaluate the methods through computer-assisted simulation surgery and surgical guide production in mandibular reconstruction using the fibula and the existing traditional method. From February 2021 to July 2022, 10 patients who underwent segmental mandibulectomy at our hospital for two years were evaluated for operation time and reconstruction time. 10 patients underwent segmental mandibulectomy and reconstruction using a surgical guide prepared in advance through 3D analysis. In addition, we compared and analyzed 5 patients who had undergone surgery by the conventional method. In segmental mandibulectomy using a surgical guide, the average operating time was 443.50 minutes with the standard deviation (SD): 88.696, and the average reconstruction time was 64.90 minutes with the standard deviation: 11.377. The average operation time using the conventional method was 517.00 minutes with the standard deviation (SD): 83.86, the average reconstruction time 77.80 minutes with the standard deviation (SD): 8.075. When the average operation time was compared, the p-value was 0.148, which was not statistically significant. In the comparison of the average reconstruction times, the p-value was 0.0425, which was statistically significant. In conclusion, it was found that in the case of mandibular reconstruction using the fibula, the operation time was shortened along with the decrease of the time in the reconstruction. The operation time in the conventional method was longer than that of the surgical guide method.
