“…During surgery, it is necessary to liberate the entrapped fibrotic tissue, especially when the inferior rectus is involved or global mobility impairment is present. 22,23 This portends implant exposure to the maxillary sinus, but an animal study demonstrated complete sinus mucosa coverage of ePTFE 1 month after implantation. 17 In this study, no implant infection or dislocation was observed.…”

ong-term posttraumatic enophthalmos (PTE) is one of the most common orbital fracture sequelae. Prompt orbital reconstruction effectively prevents long-term ocular symptoms. However, scarring and permanent changes in the skeletal structure portend residual enophthalmos. 1,2 Orbital wall and floor reconstruction using autografts or alloplastic implants is the mainstream PTE management. [3][4][5][6] Autografts have ideal biocompatibility, but are prone to resorption, with donor-site morbidity. 7 Alloplastic implants include porous polyethylene sheets 8 or titanium mesh. 9,10 The advent of Summary: Long-term enophthalmos is a common orbital fracture sequela. Various autografts and alloplastic materials have been studied in posttraumatic enophthalmos repair. However, expanded polytetrafluoroethylene (ePTFE) implantation in late enophthalmos repair has rarely been reported. The authors report novel use of ePTFE for late posttraumatic enophthalmos repair. This retrospective study included patients with posttraumatic long-term enophthalmos who underwent hand-carved ePTFE intraorbital implantation for enophthalmos correction. Computed tomography data were collected preoperatively and at follow-up. The volume of ePTFE, the degree of proptosis (DP), and enophthalmos were measured. Postoperative and preoperative DP and enophthalmos were compared using the paired t test. The correlation between ePTFE volume and DP increment was established using linear regression. Complications were identified by chart review. From 2014 to 2021, 32 patients were included, with a mean follow-up of 19.59 months. The mean volume of implanted ePTFE was 2.39 ± 0.89 mL. After surgery, the DP of the affected globe improved significantly, from 12.75 ± 2.12 mm to 15.06 ± 2.50 mm (P < 0.0001). A significant linear correlation was found between ePTFE volume and DP increment (P < 0.0001). Enophthalmos was substantially ameliorated from 3.35 ± 1.89 mm to 1.09 ± 2.07 mm (P < 0.0001). Twenty-five patients (78.23%) had postoperative enophthalmos of less than 2 mm. Infection and implant dislocation were not observed. The authors concluded that ePTFE intraorbital implantation exhibited long-term efficacy and safety for late posttraumatic enophthalmos repair and represents an effective and predictable alternative.

Purpose of review Orbital floor blowout fractures may lead to significant morbidity, including debilitating double vision and globe malposition. Thorough evaluation and timely surgical intervention may prevent long-term sequelae. Recent findings New studies have demonstrated certain patients with orbital floor fractures to do well when managed conservatively. In those necessitating operative repair, precise surgical dissection and adequate fracture reduction are essential to restoring orbital anatomy and function. Novel surgical techniques and orbital floor reconstruction materials, described in this review, will further optimize patient outcomes. Summary A knowledgeable evaluation, thoughtful management strategy and modernized surgical technique can prevent long-term disability in patients with orbital floor blowout fractures.

Early Experience With Nonporous Polyethylene Barrier Sheet in Orbital Fracture Repair

Abstract: The use of nonporous polyethylene barrier sheet implant for orbital fracture repair is a safe and effective alternative to nonporous nylon foil implants. There were no complications and one case of residual diplopia (2.1%) in this case series.
