Pediatric Orbital Floor Reconstruction Using a Nonresorbable Polypropylene-Based Hernia Mesh: A Case Report.

Orbital floor fracture is the most common type of orbit-related injury seen in pediatric age groups. It is also called a white-eyed blowout fracture when the usual signs of orbital fracture-periorbital edema, ecchymosis, and subconjunctival hemorrhage are absent. Several materials are used for orbital defect reconstruction. The most popular and widely used material is titanium mesh. We present a case of a 10-year-old boy with a white-eyed blowout fracture of the floor of the orbit of the left side. The patient had a history of trauma, after which he developed diplopia in the left eye. On examination, his upward gaze was restricted in the left eye, which was suggestive of inferior rectus muscle entrapment. The orbital floor reconstruction was done using a hernia mesh made up of nonresorbable polypropylene material. This case demonstrates the utility of nonresorbable materials in orbital defect reconstruction in pediatric patients. Further studies are needed to better understand the scope of polypropylene-based materials in the floor of orbit reconstruction and their benefits and shortcomings in the long run.
