Percutaneous Reduction of Isolated Zygomatic Arch Fractures: A 5-Year Experience.

We evaluated the outcomes and differences in surgical time and hospitalization length for patients with an isolated zygomatic arch (ZA) fracture treated by percutaneous wire reduction with external fixation. We designed and developed a retrospective study of patients with isolated ZA fractures treated from 2014 to 2019. The predictor variable was the operative treatment, represented by percutaneous reduction with external fixation. The primary outcome variables were the surgical time and hospitalization length. Other variables, including functional and esthetic results (evaluated by clinical and radiologic assessments) and the rate of immediate and delayed complications during a 6-month minimum follow-up period, were considered. Descriptive statistics were computed and compared with the international reported data. A total of 15 patients met specific inclusion and exclusion criteria. The 15 fractures were grouped using the classification reported by Kim et al as type 1A (n = 9) and type 1B (n = 6). No significant differences were found between the 2 groups, except for the fracture type. The operative treatment was performed with the patient under general anesthesia (n = 12) or local anesthesia with sedation (n = 3). Only 1 patient developed a complication (early hematoma). No other cases of early or delayed complications were reported. Two patients required a traditional surgical operation with the Gilles approach. The average hospitalization length and surgical time were 0.8 night and 18.4 minutes for the type 1A group and 0.7 night and 19.0 minutes for the type 1B group, respectively. Optimal esthetic and functional outcomes were obtained for all 15 patients. The results of the present study suggest that optimal esthetic and functional results can be obtained, minimizing the effect on soft tissues and patient discomfort, with a short surgical time and low rate of complications.
