Abstract

Purpose

The objective of this study is to present the surgical and clinical outcomes of polyster urethane implants in orbital trapdoor fracture repair in children. This is the first study reporting the use of polyster urethane implants to repair orbital fractures.

Methods

A retrospective review was performed on children with orbital trapdoor fracture who underwent surgical repair in our medical center over 6 years. The trapdoor fracture diagnosis was based on clinical findings and computed topography (CT) scans.

Results

Eight patients were identified with trapdoor fracture. All cases were repaired by polyster urethane implant. The mean age was 13.5 years and the mean follow-up was 13.6 months. All patients had orbital floor fractures. Two fractures involved also the medial wall. Seven cases had inferior rectus muscle entrapped while one had medial rectus entrapped. Three patients had residual diplopia on extreme upgaze after the surgical repair. No patient had enophalmos or infraorbital paresthesia at the end of the follow-up. No post-operative complications associated with the used material were reported.

Conclusion

Polyster urethane implant is a reliable, safe, cheap and effective implant for trapdoor fracture repair in children. It can serve as a promising alternative to other synthetic materials, for orbital floor fractures repair.
