Abstract
The aim of this network meta-analysis (NMA) was to compare the clinical results obtained after primary reconstruction of orbital floor fractures (OFF) using different materials. PubMed, Cochrane, and Google Scholar databases were screened from 1989 to 2019. For a study to be eligible, it had to evaluate two or more materials and report the following clinical parameters: diplopia and/or enophthalmos and/or other complications. Nine studies involving 946 patients presenting with an OFF were included. After the surgical procedure, 105 patients (11%) had diplopia, while 43 patients (4.5%) suffered from enophthalmos. The NMA revealed that less postoperative diplopia and enophthalmos were obtained either by using polydioxanone (PDS), or a polymer of l-lactic acid and dl-lactic acid (P[L/DL]LA), or porous polyethylene, or titanium mesh compared with the use of autologous bone grafts. P(L/DL)LA and PDS seem to be the best options for small and intermediate defects, whereas the association of porous polyethylene and titanium should be preferred for larger defects.
