EVALUATION OF VIRTUAL PLANNING AND CUSTOM-MADE TITANIUM PLATES IN TREATMENT OF UNILATERAL ZYGOMATICO-MAXILLARY COMPLEX FRACTURES - ONE YEAR PROSPECTVE CLINICAL AND RADIOGRAPHIC STUDY

Abstract

Aim To evaluate the application of mirror imaging,computer guided design and custom made titanium plates in the treatment of unilateral zygomaticomaxillary complex fractures and its role in accuracy of restoration of facial symmetryMethod Fifteen patients with unilateral zygomaticomaxillary complex fractures were included in this study were chosen from department of oral and maxillofacial surgery Alahrar teaching hospital. Preoperative CT scans were made for each patient,DICOM files were transferred to Mimics Medical19.0software for virtual planning in which mirror image of the unaffected side was used to perform virtual reduction of fractured bone and designing surgical guides and custom made plates.surgical guides were Used intraoperatively for reduction of fractured bone,And custom made plates were used for fixation of fractured bone taking in consideration anatomical features and suitable sites for screws.Use of surgical guides and custom made plates improved a lot the reduction accuracy and reduced intraoperative surgical time.All patients underwent CT scans,DICOM files were transferred to Mimics Medical19.0software for postoperative evaluation of displacement and rotation of Zygomatic bone.Results: measurements of displacement of zygomaticomaxillary complex proved that facial symmetry of all patients were improved,Accuracy of reduction increased and all patients were completely satisfied with obtained treatment resultsConclusion As with limits of current short-term prospective study, the use of surgical guide and custom-made plates is considered an effective surgical treatment in reducing and stabilizing of 0ne- sided complex zygomaticomaxillary fractures, hence it improves outcomes of clinical relations, radiological findings, as well outcomes related to patient -based findings after12 months of surgery
