Abstract:
Objective:To evaluate the effect of digital design combined with 3D printing technology in the repair of mandibular defects with fibular myocutaneous flap.Methods:From July 2017 to August 2022, 25 patients with mandibular defects repaired by fibular musculocutaneous flap after oral tumor surgery were retrospectively analyzed. The cohort consisted of 25 patients (16 male, 9 female) aged 19-68 (42.5±5.3) years. The patients were divided into two groups according to different fibula shaping methods: Study group (11 cases): digital design combined with 3D printing technology was used for fibula shaping; Control group (14 cases): conventional fibula shaping was performed based on the surgeon's experience.Results:The fibula shaping time in the study group was (51.2±4.2) min, which was shorter than that in the control group (79.1±8.0) min ( P<0.001). The study group showed higher satisfaction scores for facial appearance compared to the control group [(8.3±0.8) vs (6.9±0.6) points, P<0.001]. The survival rates were 11/11 in the study group and 13/14 in the control group, with a significantly higher survival rate observed in the study group ( P<0.001). At 3 months postoperatively, the mouth opening measurements were (3.5±0.2) cm in the study group and (3.5±0.1) cm in the control group, showed no statistically significant difference ( P=0.334). Conclusion:The application of digital design combined with 3D printing technology in fibula musculocutaneous flap reconstruction of mandibular defects reduces fibula shaping time, improves flap survival rates, and yields higher patient satisfaction with facial aesthetics.
