Purpose:
The aim of this meta-analysis was to evaluate the efficacy of open surgery and closed treatment for unilateral moderately displaced mandibular condyle fractures.
Methods:
PubMed, Embase, and Cochrane Library databases were searched according to PRISMA guidelines from inception to October, 2018. Inclusion criteria were based on humans randomized controlled trials in the English literature. Pertinent data were collected and the incidence of the complications was calculated.
Results:
A total of 6 studies with 227 patients were included in the meta-analysis. The results showed that there were no significant differences in incidence of malocclusion (odds ratio [OR], 0.33; 95% confidence interval [CI]: 0.07-1.46; P = 0.14). However, open surgery group had a better maximal mouth opening (WMD = 3.82, 95% CI: 1.93-5.71, P < 0.01), protrusion (WMD = 1.16, 95% CI: 0.42-1.89, P < 0.01) and sum of both laterotrusions (WMD: 2.50, 95% CI: 1.77-3.22, P < 0.01). And the incidence of temporomandibular joint pain was lower than closed treatment group (OR: 0.15, 95% CI: 0.06-0.37, P < 0.01).
Conclusions:
Compared with closed treatment, open surgery has significant advantages in improving mouth opening and mandibular movement, and reducing the incidence of temporomandibular joint pain, provided that open surgery was a promising application in treatment of unilateral moderately displaced mandibular condyle fractures.
