[Expert consensus on navigation-guided unilateral delayed zygomatic fractures reconstruction techniques].Zhonghua Kou Qiang Yi Xue Za Zhi 2019; 54(6):363-367ZK
The zygoma is located in the medial and lateral parts of the face, supporting the midfacial contour. The forward projection of the zygoma and the zygomatic arch expose them to frequent injury. Fractures of the zygoma can lead to displacement of the zygoma and the zygomatic arch, causing facial collapse deformity. For delayed zygomatic fractures, the loss of normal anatomical landmarks, caused by the malunion of the fracture lines and remodeling of the bony contour, makes it difficult to determine the correct positions of the zygomatic bones. In such cases, using traditional surgical methods, ideal and steady outcomes with satisfactory midface symmetry have been difficult to obtain. Nowadays, the application of digital surgical software and surgical navigation help surgeons to perform accurate preoperative simulations to obtain ideal 3-dimensional (3D) virtual surgical plans, and achieve accurate reduction by intraoperative navigation systems, which increase the accuracy and predictability of fracture reduction outcomes. Experts from the Oral and Maxillofacial Surgery Committee of the Chinese Stomatological Association have fully discussed and formulated an expert consensus on navigation-guided unilateral delayed zygomatic fracture reconstruction techniques, to standardize the clinical operation procedures and promote the application.
