The analysis included age distributions of the children, reasons and places for the trauma, and positions and severity degrees of the trauma. The questionnaires were carried out for the patients′ mothers, to understand the cognition degrees and prognosis factors. Results Most of the patients with facial trauma were aged 1-6, with the male and female ratio of 1.4∶1. Falls were the leading cause for the maxillofacial injuries（83.33%）. The most common types of injury were the soft tissue injuries（63.43%） and the teeth injuries（31.94%）, the jaw fractures were least. 50.00% accidents occurred at home. 97.22% mothers had no knowledge of the facial injuries in children. 69.44% mothers thought it avoidable. It were relevant between mothers′ educations and injuries times（掊2=18.16, P<0.05）. Conclusion Mothers lack the knowledge is one of the most important reasons for the maxillofacial injuries in children.
