ABSTRACT
BACKGROUND:
Following mandibular reduction, bone regeneration in the angle region is a problem that can affect facial aesthetics and lead to revision surgery. The bone regeneration rate (BRR) varies between individuals and is difficult to predict. However, studies focusing on preoperative patient-related factors are lacking. As bone regeneration is closely related to the inflammatory and immune status of the organism, according to in vitro and in vivo evidence, preoperative inflammatory indicators were included in this study as potential predictors.METHODS:
Demographic and preoperative laboratory data were included as independent variables. The BRR calculated from computed tomography data was included as the dependent variable. Univariate analysis and multiple linear regression analysis were used to determine the key factors influencing the BRR. The ROC curves were used to analyse the corresponding predictive efficacy.RESULTS:
23 patients (46 mandibular angles) fulfilled the inclusion criteria. The mean bilateral BRR was 23.82 ± 9.90%. Preoperative monocyte count (M) was an independent positive factor for BRR, and age was a negative factor. Only M had a good predictive ability, and its optimal cut-off point to distinguish patients with BRR greater than 30% was 0.305 × 109/L. Other parameters were not significantly correlated with BRR.CONCLUSIONS:
Patient age and preoperative M may influence BRR, with M having a positive effect and age having a negative effect. According to the preoperative blood routine tests that are readily available, using the diagnostic threshold (M [Formula see text] 0.305 × 109/L) derived from this study, surgeons can better predict BRR and identify patients whose BRR is greater than the mean level.
