Abstract

Purpose: In the present study we demonstrate the surgical reconstruction of a unique midface injury caused by a glider plane accident. Additionally, we demonstrate the usefulness of an in-house developed software that allows preoperative surgical planning using three-dimensional models of the injured sites. Methods: Reconstruction was carried out with the help of a novel virtual preoperative planning procedure developed by our team. Axial CT scans were used to generate the three-dimensional geometry of the skull and then preoperative virtual fracture repairs were performed by plate fixation using in-house developed JMed software system (TraumArt Ltd.; Department of Traumatology and Department of Image Processing and Computer Graphics, University of Szeged, Szeged, Hungary). The software is designed to render a three-dimensional model of the lesioned areas using CT images, and it allows the user to perform preoperative virtual surgical planning. According to the set parameters, surgical procedure was performed five days after the accident when facial swelling and hematoma were fully elapsed. Results: Primary wound healing took place without infectious complications. Movements of the left eye were successfully preserved, and excellent visual acuity was recorded. No facial asymmetry was detected, and the esthetic results were fairly acceptable for the patient. Conclusion: Our in-house developed software system appears to be an effective tool to render a threedimensional model of the injury and test surgical options of facial reconstruction preoperatively on this model. This software may prove to be a valable asset in various surgical fields in the future.
