Distribution of gender showed significant difference (p < 0.001). Differences between proportions of patients undergoing immediate or delayed maxillofacial surgery based on major or minor lesions reached statistical significance (χ2 = 557.2, p < 0.0001); moreover, proportions of concomitant lesions were significantly different between major and minor lesions groups (χ2 = 17.13, p < 0.0001).

One patient was the victim of a gunshot wound. Four patients died before maxillofacial surgical treatment.
