Many methods of surgical repair of pure medial
orbital fractures have been reported. In this study, we discuss the outcome from the surgical corrections of
hydroxyapatite (
Biocoral) or porous
polyethylene (
Medpor) through subciliary approach, and the transnasal endoscopic corrections. Between March 1993 and July 2003, 63 patients were treated with porous
polyethylene and 48 patients were treated with
hydroxyapatite. Between August 2003 and December 2005, 50 patients were treated with transnasal endoscopic approach. Patients had at least 6 months' follow-up, and the records for
diplopia,
enophthalmos, and other postoperative complications were reviewed retrospectively. As a result, 1 patient from the group using porous
polyethylene, 2 patients from the group using
hydroxyapatite, and 1 patient from the endoscopic correction group had
enophthalmos. Besides
enophthalmos, no other complications were observed. There was no significant statistical correlation among 3 groups. In conclusion, a transnasal endoscopic correction may be considered a useful method for surgical repair of pure medial
orbital fractures, with no external facial
scar and excellent visualization and accuracy comparable to that of the subciliary approach.
