Objectives: To investigate the influence of platelet volume indices (PVI) on postoperative pain and edema in patients undergoing bimaxillary surgery and assessed the associations between PVI parameters and other clinical factors.
Methods: We examined the medical records of 50 patients aged 18-40, treated between 2019 and 2020. Platelet indices (platelet count [PLT]), mean platelet volume, platelet distribution width, plateletcrit (PCT), and platelet large cell ratio) were analyzed. Postoperative pain and edema were assessed based on the frequency of intravenous (IV) analgesic administration and 3D imaging. A lasso-penalized regression was used for the analysis.
Results: Significant positive correlations were observed between PLT and postoperative edema on the first (T1-0) and third (T3-0) postoperative days. Furthermore, PLT was positively associated with the number of IV analgesic drug administrations from 24 to 72 hours after surgery. Additionally, a discernible positive correlation was identified between PCT levels and the quantity of IV analgesic drugs administered within the first 24 hours after surgery.
Conclusion: Platelet indices, particularly PLT and PCT levels, were associated with postoperative pain and edema in patients undergoing bimaxillary surgery. These indices have the potential to serve as biomarkers for predicting and managing postoperative complications of orthognathic surgery. Further studies are required to explore the clinical utility and implications of these findings.
