Minimally Invasive Single-Point Stabilization of Zygomaticomaxillary Complex Fractures

This study aimed to present a minimally invasive surgical management of zygomaticomaxillary complex (ZMC) fractures with reduction and single-point stabilization over the frontozygomatic buttress.

This prospective cohort study was conducted on cases of ZMC fractures. The inclusion criteria were displaced tetrapod zygomatic factures, asymmetry of the facial bones, and unilateral lesion. The exclusion criteria were extensive skin or soft tissue loss, comminuted inferior orbital rim, limited ocular mobility, and enophthalmos. Surgical management included reduction and single-point stabilization over the zygomaticofrontal suture with miniplates and screws. The outcome measure was correction of the clinical deformity with less scarring and low postoperative morbidity. The late outcome was maintenance of a stable fixed reduced zygoma over the follow-up period.

Forty-five patients were included in the study with a mean age of 30 ± 5.56 years. The study included 40 men and 5 women. Motor vehicle accident was the most common cause of fracture (62.2%). They were managed via lateral eyebrow approach with single-point stabilization over the frontozygomatic suture after reduction. Preoperative and postoperative and radiologic images were available. All cases had optimum correction of the clinical deformity. Postoperative stability was excellent in the follow-up period, which had a mean of 18.5 ± 7.81 months.

There is an increased interest in minimally invasive procedures, and concerns about scarring have increased. Therefore, single-point stabilization over the frontozygomatic suture provides good support to the reduced ZMC with low morbidity.
