Evaluation of orbital volume after orbitozygomatic complex fractures fixation: A radiographical study

Abstract

BackgroundOrbitozygomatic complex fractures are one of the most commonly encountered injuries of the craniofacial skeleton. The aim of this study was to implement the orbital volume as an objective evaluation modality for the assessment of the accuracy of unilateral Orbitozygomatic complex fracture fixation, by comparing the postoperative values with the contralateral normal side and the pretreated values. Materials and methodsA retrospective radiographic, chart review was performed in order to investigate the primary outcome of the objective quantification of the accuracy of Orbitozygomatic complex fracture reduction utilizing orbital volume analysis. Comparing the postoperative orbital volume values with the preoperative, and the contralateral normal ones was set as the study secondary outcome, along with the percentage of changes in the orbital volume of unilateral Orbitozygomatic complex fracture treated patients. Data reliability was performed using Interclass correlation coefficient and Statistical significance was set at 5% level. ResultsSeventeen records met the inclusion criteria. While a statistically significant difference was found between the preoperative orbital volume values of the affected side and that in the normal unaffected side (P < 0.001), a statistically insignificant difference was encountered between the postoperative values and the control side (P = 0.333). An average percentage of decrease of 6.1%. was reported in the postoperative records when compared to the preoperative ones, with a statistically significant difference (P < 0.001). the study reported high inter (ICC = 0.97) and Intra (ICC = 0.97) observer reliability. ConclusionOrbital volume analysis offers a valid modality for the objective evaluation of the efficiency of Orbitozygomatic complex fracture management.
