Objective To provide references for clinical management of patients with orbital blow-out fractures. Methods Evidence was retrieved from The Cochrane Library online (Issue 1, 2009), ACP online, NGC (1998 to March 2009), PubMed (January 1950 to February 2009), and CBM (1994 to February 2009). The collected evidence was then graded. Results After preliminary research, we identified 12 relevant articles: either retrospective studies or comments from specialists. They studied orbital soft tissue entrapment, diplopia, enophthalmos, or severe oculocardiac reflex in the surgical indications of orbital blow-out fractures. Most of the literature suggested less than five days after the injury incursion for children and less than two weeks for adults was the optimal time to undergo operation. However, advanced surgery was still a good option for the patients that could not undergo early surgery. With regard to the use of poly-pdioxanon- foil and titanium-dynamic mesh, two randomized controlled trials suggested that the former was superior to the latter. Conclusion The application of this surgery should be cautious because of low levels of evidence. Individual therapies should be used after close consideration of clinical characteristics.
