OBJECTIVE

To analyze vascularized autograft remodeling after reconstructive surgery in patients with jaw defects and deformities.

MATERIAL AND METHODS

The study included 30 patients aged 17—65 years with jaw defects who were treated at the Central Research Institute of Dentistry and Maxillofacial Surgery between 2016 and 2020. The first group consisted of 23 patients who underwent jaw reconstruction for benign neoplasms and injuries; the second group — 7 patients with malignancies (resection followed by radiotherapy). CT was performed in 6 months after these procedures and 6 months after dental implantation in all patients. To assess density and dimensions of vascularized fibular autograft, we analyzed the ratio of thickness of two cortical layers to bone thickness (cortical index, CI). CI was calculated in vertical and transversal planes (CI-V and CI-T). Remodeling index (RI) was used to analyze functional state of the vascularized autograft. RI is a ratio of transverse measurement of the vascularized autograft (present study) to the same measurement in the previous study. RI was also calculated in vertical (RI-V) and transversal planes (RI-T).

CONCLUSION

Autograft remodeling in 6 months after reconstructive surgery and 6 months after dental implantation is significantly worse in patients with previous radiotherapy.
