Comparison of application of three dimensional microscope and optical microscope in oral and maxillofacial vascular anastomosis

Objective To investigate the application value of 3D microscope in vascular anastomosis in oral and maxillofacial surgery, to provide a reference for clinicians. Methods Eighty-seven cases of free flap reconstruction in oral and maxillofacial surgery were retrospectively included, including 30 cases in the 3D microscope group and 57 cases in the optical microscope group. The differences in intraoperative vascular anastomosis time, postoperative flap survival rate and doctor evaluation scores between the 3D microscope group and the optical microscope group were compared and statistically analyzed, and the feasibility of using three-dimensional microscope in surgery was evaluated. Results The arterial anastomosis time was (26.53±3.83) min/root in the 3D microscope group and (24.88 ± 2.97) min/root in the optical microscope group, and the difference was statistically significant (P
