Digital navigation and 3D model technology in mandibular reconstruction with fibular free flap: A comparative study - 17/09/21
Abstract |
Objective |
The low accuracy limits the use of fibular free flap (FFF). We apply digital navigation and 3D printing model technology in mandibular reconstruction to improve FFF’s accuracy.
Methods |
34 patients who underwent with FFF to repair mandibular defects were divided into Navigation Group (13 cases, using digital navigation and 3D printing model) and Control Group (21 cases, only 3D printing model). We retrospectively reviewed patients’ hospitalization information and evaluated patients by subjective and objective items, such as UW-Qol scale, CT data.
Results |
The operation time of Navigation Group was higher significantly than Control Group (10.36 ± 1.87vs9.00 ± 1.34 h).There were no significant differences in early postoperative complications. The Qol score of appearance, motion, anxiety were higher significantly in Navigation Group. The CT results showed that mandibular angle deviation and chin deflection of Navigation Group were better significantly than Control Group (1.72 ± 1.29° vs 3.69 ± 1.67°, 2.45 ± 1.39 vs 5.19 ± 2.13 mm).
Conclusions |
The digital navigation can improve FFF’s accuracy in mandibular reconstruction. It doesn’t significantly increase complications. The digital navigation’s installation and operation methods should be simplified to shorter operation time and expand its application.
