Abstract
Pediatric maxillary and zygomatic fractures are rare due to the anatomic protection and increased bone stability. They are typically the result of high-energy trauma resulting from motor vehicle collisions. As such, they are most commonly seen with concomitant injuries. After stabilization of life-threatening injuries, a thorough history of the inciting injury and careful physical exam of the facial skeleton must be completed. Computed tomographic imaging with three-dimensional analysis of the maxilla and zygomaticomaxillary complex is essential to an accurate diagnosis and proper treatment plan. Conservative, nonsurgical management is reserved for non-displaced or minimally displaced midface fractures with no functional or esthetic deficits. When fractures of the maxilla occur and result in a malocclusion, closed reduction utilizing maxillomandibular fixation can be considered. When the maxilla or zygoma are displaced and more significant functional or esthetic deficits result, open reduction with or without fixation may be necessary. The benefit of restoring form and function must always be weighed against the consequences of operating on the pediatric patient. The soft-tissue scarring and bony trauma created during surgical access, reduction, and fixation of the facial skeleton may lead to growth disturbances in the growing child. The use of biodegradable fixation systems avoids the second surgery required to remove hardware when titanium fixation is used. However, more data is needed to assess whether this benefit carries any growth advantage. In general, bone healing is accelerated in pediatric populations and therefore the timing of conservative treatments and closed reduction techniques is shorter in comparison to that in adults. Long-term complications from pediatric maxillary and zygomatic fractures include hypoplasia of the affected bones and bony asymmetry. Close longitudinal follow-up of these patients with early recognition of growth disturbance may allow for growth modification techniques prior to skeletal maturity and alleviate the need for further surgical intervention in the adult years.
