Abstract
Purpose
This study aimed to determine via systematic review and meta-analysis the proportion of maxillofacial trauma resulting from different etiologies among children and adolescents.
Methods
A systematic review of articles published from 2006 to 2015 (10 years) in English language was performed. The following databases were used: PubMed/MEDLINE, Scopus, and Web of Science. Observational studies reporting the number of children and/or adolescents who suffered maxillofacial trauma resulting from different etiologies were included. Studies were selected by two independent reviewers (Kappa = 0.737). A proportion meta-analysis using random-effect models was performed to estimate the pooled prevalence and the 95% confidence intervals (CI) using Der-Simonian and Laird weights. Heterogeneity among studies was assessed using the I 2 statistics.
Results
A total of 27 studies remained after qualitative analysis including 402,339 patients. The male/female ratio ranged from 1.5:1 to 3.5:1. Road traffic accidents corresponded to the main etiology agent of maxillofacial trauma (34%; 95% CI, 25–44), followed by falls (31%; 95% CI, 25–37), violence (11%; 95% CI, 4–19), sports (4%; 95% CI, 3–5), and others (5%; 95% CI, 2–8). Heterogeneity among studies was high, even stratifying by world region. The adapted version of the Newcastle-Ottawa scale for observational studies showed an intermediate score for most of the included studies.
Conclusions
Results suggest that road traffic accidents represent the main cause of maxillofacial trauma among children and adolescents. However, results should be interpreted with caution due to the high heterogeneity.
