This article aimed to characterize, compare, and contrast the management of isolated orbital floor fractures among oculofacial and facial plastic surgeons in the United States. An anonymous 17-question multiple-choice web-based survey was distributed to all 590 members of the American Society of Ophthalmic Plastic and Reconstructive Surgery (ASOPRS) and all 1,300 members of the American Academy of Facial Plastic and Reconstructive Surgery (AAFPRS) using each society's email database from November 2016 to January 2017. Two-hundred twenty-five oculofacial and 135 facial plastic surgeons completed the survey. The most important indications for surgery among both oculofacial and facial plastic surgeons were motility restriction, enophthalmos, and diplopia at 2 weeks. The most common preferred time to surgical intervention was 8 to 14 days; however, facial plastic surgeons were more likely to operate after 4 to 7 days ( p < 0.001). The most common choices of orbital implant material were porous polyethylene and porous polyethylene plus titanium for both oculofacial and facial plastic surgeons, nylon for oculofacial surgeons, and titanium for facial plastic surgeons. The majority rarely/never used intraoperative computed tomography imaging or navigation. Facial plastic surgeons were more likely to perform postoperative imaging ( p < 0.001). We report results of the first survey of isolated orbital floor fracture management among oculofacial and facial plastic surgeons in the United States. This survey characterizes practice patterns and areas of similarities/differences among oculofacial and facial plastic surgeons in the management of isolated orbital floor fractures, which may help define the current standard of care.

Background: Resorbable mesh and porous polyethylene are frequently used alloplastic materials for the treatment of the orbital blowout fractures. The literature lacks reports comparing their long-term effects on experimental models. Objective: Our aim was to radiologically and histologically evaluate the effectiveness and safety of porous polyethylene and resorbable mesh in a rabbit orbital blowout fracture model. Methods: Twelve New Zealand white rabbits (24 orbits) were randomized to 4 groups. In group 1, only orbital floor dissection was done. In group 2, following orbital floor dissection, a 10-mm defect was created without any extra procedure. In group 3, following a 10-mm defect creation, a 12-mm-round cut porous polyethylene was placed on the defect. In group 4, following a 10-mm defect creation, a 12-mm-round cut resorbable mesh was placed on the defect. Computed tomographic analysis was performed during follow-up period. Orbital floors were evaluated histologically at month 6. Results: No clinical complications were observed during follow-up period. In radiological evaluation, there was no statistically significant difference between groups regarding bone formation. In histological evaluation, the connective tissue was denser, and organized and better bone formation was observed in group 3 and 4 when compared with other groups. Conclusion: Although no significant radiological changes were present, porous polyethylene and resorbable mesh performed better histologically. They were effective and well tolerated for reconstruction of the isolated orbital floor defects.

Orbital Floor Fractures

The purpose of this retrospective study was to investigate treatment options for orbital floor fractures at a Level 1 Trauma Center in Southern California. A review of 45 cases of isolated orbital floor fractures treated at the University of California at Irvine between February 2004 and April 2007 was done. Patients were retrospectively analyzed for gender, age, mechanism of injury, associated facial injuries, presenting symptoms, method of treatment, and postoperative complications. Thirty-six male patients and nine female patients were treated. Motor vehicle collision (26/45) was the most common cause of injury, and the mean age of the patients was 35.5 years (range: 15—81 years). Ecchymosis surrounding the orbital tissue was the most common presentation (38/45). Diplopia was present in 8 of 45 patients, with 1 patient requiring urgent decompression for retrobulbar hematoma. Forty-three patients underwent surgical repair; 40 underwent transconjunctival approach with lateral canthotomy; 17 underwent reconstruction with porous polyethylene Medpor (Porex Surgical, Inc., College Park, GA.); and 26 underwent reconstruction with a titanium mesh plate. Immediate postoperative complications included 12 patients with infraorbital numbness, 3 with diplopia, 1 with cellulitis, and 1 with ectropion with a subcilliary approach. Average timing of surgery of our study was 4.94 days (range, 1—20 days). Orbital floor fracture management has changed significantly over the past few decades with the introduction of new internal fixation methods and new materials for reconstructing orbital floor defects. Recommendations for surgical intervention on orbital floor fractures mostly depend on clinical examination and imaging studies. Consequences of inadequate repair of orbital floor fractures can lead to significant facial asymmetry and visual problems. Both porous polyethylene and titanium plates are effective tools for reconstructing the orbital floor. Our review demonstrates that orbital floor fractures can be repaired safely with minimal postoperative complications and confirms that transconjunctival approach to orbital floor is an effective way for exposure and prevention of ectropion that can be seen with other techniques.
