Compared Healing of Mandibular Condylar Fractures with Open and Closed Reduction Surgical Methods (Radiological Analysis, Gray Scale)

Objective: This study aimed at comparing the bone healing process in mandibular condylar fractures treated with ORIF and closed reduction methods radiographically with the use of Gray Scale Value (GSV). Methods:The study involved 30 patients with condylar fractures who were treated and divided into two groups: Group A: Treatment with ORIF (15 patients); Group B: Treatment with closed reduction (15 patients). GSV analysis on orthopantomography (OPG) was presented in Pixel Value Ratio (PVR), which compared GSV value of fracture area and healthy bone. Observations were made on day 1, week 2, weeks 8-13, and >13 weeks postoperatively. Results: The majority of the subjects were male, 26-28 years of age on average, all with traffic accident trauma etiology. Results of repeated measure ANOVA showed that PVR value in both groups increased significantly at all observation times with P=0.000, and the PVR value in the ORIF group was higher. T-test results showed that PVR value in ORIF group was higher than closed reduction group at all observation times (0.001, 0.003, 0.005, and 0.018). Conclusion: GSV and PVR values in ORIF group were found higher than those in closed reduction group, which means that healing in ORIF group was better than in closed reduction group.
