To investigate the long-term results and complications of orbital wall fracture reconstruction using the bioabsorbable orbital implant, Macropore® orbital floor liner.

This retrospective study included patients who underwent the reconstruction of an orbital wall fracture using Macropore® orbital floor liner and completed a postoperative follow-up longer than 6 months. The enophthalmic values as well as the data of ocular movement and diplopia was collected from the medical records of each patient and analyzed.

A total of 35 patients were evaluated with an average follow-up period of 14.0 months. The average enophthalmic value of 29 patients, whose reconstruction was primarily indicated from enophthalmic tissue, was 0.90 mm at the last follow-up. No significant progression of enophthalmos was observed at postoperative 12, 18 and 24 months when compared with the enophthalmic value at postoperative 6 months. All 15 patients who have had the limitation of ocular movement or diplopia preoperatively resolved completely or improved to the degree that no clinically significant limitation or diplopia further existed. No complications such as dislocation of implant, infection, and aggravation of ocular limitation were observed during the follow-up period.

Macropore® orbital floor liner may be regarded as a useful implant in reconstruction of orbital wall fracture with no significant implant-related complications during its absorption.
