Exclusion criteria included patients under the age of 18, patients who sustained additional maxillofacial fractures including zygomaticomaxillary complex fractures, and patients who were found to have a chronic fracture. Inclusion criteria included patients 18 years of age or older who sustained an isolated zygomatic arch fracture confirmed by computed tomography (CT) scan. Patients were identified using international classification of diseases (ICD)-9/10 and common procedural technology (CPT) codes. The purpose of this study is to portray our institutional experience and procedural outcomes in the management of isolated zygomatic arch fractures.Īfter institutional review board approval, a retrospective chart review of patients who sustained isolated zygomatic arch fractures from 2010 to 2018 was conducted at our institution, a level 1, tertiary care center. Furthermore, previous larger studies on isolated zygomatic arch fractures are outdated, 4 – 6 and an update is warranted. 1 Additionally, there is an insufficiency in data on external fixation of isolated zygomatic arch fractures. Surprisingly, clinical outcomes based on these different techniques have not been well studied. After achieving successful reduction, the zygomatic arch fracture may need fixation. The 2 most common approaches are the Gillies temporal approach and the Keen intraoral approach. There are different surgical approaches that vary in exposure, reduction methods, whether to perform fixation, and the type of fixation used. Displaced fractures should be reduced and fixed within 2 weeks failing to do so can result in functional and aesthetic concerns. 3 Isolated, nondisplaced fractures may be treated nonoperatively, whereas displaced zygomatic arch fractures are usually treated with surgical reduction with or without fixation. 1, 2 Fractures of the zygomatic arch compromise 10% to 15% of all facial fractures and are typically the result of a direct blow to the face. The zygomatic bone forms the lateral aspect of the midface and comprises the lateral and the inferior orbital rim and malar eminence, thus creating facial width and projection.
