Open Versus Closed Treatment of Unilateral Moderately Displaced Mandibular Condylar Fractures: A Meta-Analysis of Randomized Controlled Trials

Oral Surg Oral Med Oral Pathol Oral Radiol. 2013 Aug;116(2):169-73. doi: 10.1016/j.oooo.2013.02.023. Epub 2013 May 7.


Purpose: To compare the efficacy of operative and conservative treatment of displaced condylar fractures of the mandible, a meta-analysis was performed.

Study design: PubMed, Cochrane Controlled Trials Register, EMBASE electronic databases were searched until 10 December 2012. English studies were restricted in randomized controlled trials (RCT).

Results: Four RCT with 177 patients were included. No significant difference was found between the 2 groups in the maximal interincisal opening (P = .32). However a statistically significant difference was seen that operative treatment statistically got better efficacy in lateral excursion movement, protrusion, malocclusion, and temporomandibular joint pain (P < .05).

Conclusions: This meta-analysis confirms that both treatment options for unilateral displaced condylar fractures of the mandible yielded acceptable results. However, operative treatment was superior in most objective and subjective functional parameters.
