RESUMO
PURPOSE: There are a variety of implant materials available for orbital floor fracture repair. Implant selection is guided by surgeon experience, availability, and patient specific needs. The purpose of this study is to describe a "wraparound" technique for nylon foil implant placement for large, isolated floor fractures that provides excellent results with low incidence of enophthalmos or other complications. MATERIALS AND METHODS: A retrospective chart review from 2012 to 2020 was conducted in patients who underwent isolated orbital floor fracture repair with the use of the "wraparound" nylon foil implant. The surgical technique is described. Preoperative CT scans were assessed, and the patients were divided into groups based on the size of the floor fracture. Postoperative data was collected including Hertel measurements and complications related to the implant. RESULTS: There were eighty patients who underwent orbital floor fracture repair with the described technique and had adequate follow-up. There were 18 (22.5%) small-sized fractures, 32 (40%) medium-sized fractures, and 30 (37.5%) large-sized fractures in the study group. One patient (3.33%) in the large fracture group had clinically significant enophthalmos of 2 mm postoperatively. There were no other patients with clinically significant enophthalmos. There were no instances of any complications related to the implant, and no patients required implant removal. CONCLUSIONS: The "wraparound" technique for a nylon foil implant provides excellent results for isolated orbital floor fractures. It provides more support and stability than traditional nylon implants for larger fractures and has minimal complication rates.
