Prevalence of Ocular Complications in Patients with Zygomatic Bone Fractures in an Iranian Population

Objectives: Damages to the middle third of the facial bone generally involve the orbital skeleton and can lead to eye impairment. In this study, it is attempted to determine the incidence of ophthalmic injuries in maxillofacial trauma with zygomatic bone fractures. Materials and Methods: One hundred and fifteen cases with ophthalmic (ocular) involvement after maxillofacial trauma were referred to the Shariati Hospital, Tehran, Iran, and were visited at the Ophthalmology Department between 2016 and 2018. Zygomatic fractures and resulting ocular complications were evaluated in 87 males and 28 females with the mean ages of 26 and 32 years, respectively. Results: Subconjunctival ecchymosis was detected in 23.07% of men and 21.05% of women. Displacement of the palpebral fissure was detected in 26.5% of men and 27.6% of women. Furthermore, the unequal pupillary level was observed in 18.37% of men and 15.78% of women. Diplopia was detected in 8.9% of men and 10.5% of women. Additionally, enophthalmos was observed in 23.1% of men and 25% of women. Conclusion: The most common ocular presentations in midfacial trauma are diplopia and reduced visual acuity. Even after the operation, a significant number of patients experience poor vision and diplopia. Ophthalmology consultation is essential for these patients.

Prophylactic Midface Lift in Midfacial Trauma

The objective was to review our favorable experience in the use of prophylactic midface lifts in the setting of severe midfacial trauma. A retrospective review of a consecutive series of patients undergoing prophylactic midface lifts at the time of definitive fracture repair in a County Hospital Level 1 trauma center was done. All patients undergoing midface lifts at the time of fracture repair by the senior author from July 1998 to July 2012 were included in this review. A total of 72 patients (58 males, 14 females, average age: 36.2 years) were available for review. Sixty-three patients had a minimal follow-up of at least 3 months. No complications felt to be related to the midfacial suspension were noted. There were no instances of frontal nerve paralysis or palsy. There were no patients with ectropion. Patient midfacial symmetry was evaluated by two blinded facial plastic surgeons. It was felt to be excellent in 53 patients, good in 9, fair in 1, and poor in none. The force of trauma necessary to elicit a severe midfacial fracture and the subsequent subperiosteal dissection required to expose the fractures for rigid fixation result in severe laxity of the midfacial soft tissue envelope. Failure to suspend and support these soft tissues will result in significant facial asymmetry. Prophylactic endoscopic midface suspension appears to be a safe and effective method of largely eliminating this problem and should be considered in the setting of severe midfacial fractures.
