A study compared patient presentation, surgical decision-making, and outcomes between isolated orbital floor fractures (I-OF) and zygomaticomaxillary complex fractures (Z-OF). Differences were found in symptoms presentation, preoperative observational periods, postoperative motility restrictions, and risk for eyelid complications between the two fracture types. Z-OF fractures had reduced postoperative motility defects but higher risk of eyelid complications compared to I-OF fractures.
Orbital floor fractures are common sequalae of trauma to the orbit. These fractures present as an isolated orbital floor (I-OF) fracture or with other midface fractures, typically the zygomaticomaxillary complex. The authors sought to better understand the differences in patient presentation, surgical decision-making, and outcomes in I-OF fractures compared with those associated with zygomaticomaxillary complex fractures (Z-OF). A retrospective review of patients with orbital floor fractures was conducted to generate an I-OF fracture group and a Z-OF fracture group. Demographics, preoperative symptoms, surgical choices, and postoperative complications were assessed. Complications were assessed individually and as 2 composite groups consisting of orbital complications and eyelid complications. There were 156 patients that met inclusion criteria with 75 I-OF fractures and 81 Z-OF fractures. The most common mechanism of injury for I-OF fractures was assault (34.7%) and motor vehicle accidents (39.5%) for Z-OF fractures. The I-OF group presented more often with diplopia (P = 0.01) whereas the Z-OF group had more trauma symptoms (P = 0.01), which included subconjunctival hemorrhages, retrobulbar hemorrhages, and relative afferent pupillary defects. I-OF fractures had longer preoperative observational periods (P < 0.001). Postoperatively, I-OF fractures had more motility restrictions (P = 0.002) but Z-OF fractures had higher risk for eyelid complications (P = 0.03). There was no significant difference in reoperation rates (P = 0.93). Multivariate analysis showed Z-OF fractures had reduced a rate of postoperative motility defects by 72% (P = 0.03) but had 2.6 times higher risk of eyelid complications (P = 0.04). Z-OF fractures present differently, vary in surgical management, and have complications that differ from an I-OF fracture.
