A multi-outcome analysis of the effects of treatment timing in the management of zygomatic fractures

Abstract

The aim of this study was to analyze the effects of surgical treatment delay in the management of zygomatic fractures. A retrospective case series of 99 patients was undertaken. Four outcome measures were analyzed in relation to delay: facial symmetry, facial scarring, trismus, and radiographic outcome. Five additional variables were subsequently analyzed: operation, diagnosis, primary operator, regular alcohol use, and regular cigarette use. Statistically significant associations were found between delay and facial scarring, and delay and radiographic outcome. For each additional delay of a day, the odds of facial scarring being present, compared to absent, decreased by 13% (odds ratio (OR) 0.87, 95% confidence interval (CI) 0.76–0.98). For regular cigarette users, for each additional day of delay there was a 306-fold increased risk of having a radiographic outcome of major deviation from premorbid compared to equivalent to premorbid (OR 306.38, 95% CI 2.08–45,161.49). For non-regular cigarette users/non-users, for each additional day of delay there was a 1.5-fold increased risk of having a radiographic outcome of major deviation from premorbid compared to equivalent to premorbid (OR 1.50, 95% CI 1.08–2.09). These findings correlate with commonly held beliefs and anecdotal evidence. Despite the limitations, this study allows for an evidence-based approach to the timing of treatment of zygomatic fractures.
