Purpose: Fibrous dysplasia (FD) is a benign condition in which normal cancellous bone is replaced by immature woven bone and fibrous tissue. The present study aimed to estimate and compare the 3-dimensional (3D) accuracy of bone contouring surgery for zygomaticomaxillary FD performed using virtual planning and surgical navigation versus surgeon's intraoperative assessment.
Patients and Methods: This is a retrospective cross-sectional study. Patients with zygomaticomaxillary FD who underwent bone contouring surgery between 2012 and 2019 were reviewed. They were divided into 2 groups: group A underwent bone contouring surgery using virtual planning and surgical navigation, and group B underwent bone contouring surgery by surgeon's intraoperative assessment. The predictor variable was surgical technique. The other variables were gender, age, and operative region. The primary outcome variable was 3D accuracy, which was indicated by root mean square, calculated as a measure of the deviation of the postoperative computed tomography from the preoperative virtual plan. The other outcome variables were patient satisfaction with the outcome by self-evaluation score and operative times. Correlation analysis between the predictor variables and outcome variables was performed.
Results: The sample comprised 24 patients (17 males and 7 females, mean age, 25.7 ± 10.45 years), 13 patients in group A and 11 patients in group B. The mean root mean square was significantly lower in group A than in group B (P = .007). Patient satisfaction with facial symmetry was significantly better in group A (P = .015). Mean operative time was comparable between the 2 groups (P = .918). Surgical technique (P = .011) and operative region (P = .01) were significant influence factors in 3D accuracy of surgery.
Conclusions: Virtual planning and surgical navigation can significantly improve the 3D accuracy and patient satisfaction of bone contouring surgery for zygomaticomaxillary FD, without prolonging operative time.
