Abstract

BACKGROUND AND OBJECTIVES
The purpose of this study was to share our clinical experience on the use of bioresorbable poly L-/DL-lactide 70/30 implant to repair blow out fracture.
SUBJECTS AND METHOD
The medical records of 130 patients with orbital fractures that were treated surgically from June 2006 to February 2011 were reviewed retrospectively. Patients who had diplopia or limited extraocular motion, significant Enophthalmos (>2 mm), or a large orbital wall fracture on a computed tomographic scan were enrolled for the study. We investigated diplopia, limited extraoacular motion, enophthalmos before and after surgery.
RESULTS
The mean postoperative follow-up was 28 months. There was no evidence of sinus infection related to the implant. However, six patients showed dislocation of orbital implant in the nasal cavity. After six postoperative months, diplopia was seen in 1 (2%) patient, and significant enophthalmos was seen 2 (2%) patients. We carried out re-operation on six cases and the main cause was incomplete reduction or over reduction.
CONCLUSION
Bioresorbable poly L-/DL-lactide 70/30 implants are safe and reliable for the reduction for blowout fracture.
