Materials Used for Reconstruction After Orbital Floor Fracture
Journal of Craniofacial Surgery, 2012
Advances in biotechnology continue to introduce new materials for reconstruction of orbital floor fractures. Which material is best fit for orbital floor reconstruction has been a controversial topic. Individual surgeon preferences have been supported by inconsistent inconclusive data. The purpose of this study was to assess and analyze published evidence supporting various materials used for orbital floor reconstruction and to develop a decision-making algorithm for clinical application. A systematic literature review was performed from which 48 studies were selected after primary and secondary screening based on set inclusion and exclusion criteria. This cumulatively included 3475 separate orbital floor reconstructions. Results revealed risk and benefit profiles for all materials. Autologous calvarial bone grafts, porous polyethylene, and polydioxanone (PDS) were most widely used for orbital floor reconstruction. Increased infection rates were reported with polyglactin 910/PDS composites and silastic rubber. Ocular motility was reduced most with lyophilized dura and PDS. Preoperative and postoperative rates for diplopia and enophthalmos varied among the materials. In conclusion, our results revealed continued inadequate evidence to exclusively support the use of any one biomaterial/implant for orbital floor reconstruction. Results have served to create a decisionmaking algorithm for clinical application. Our authors propose certain parameters for future studies seeking to demonstrate a comparison between 2 or more materials for orbital floor reconstruction.
Alternative Methods for Reconstruction of Orbital Floor Defect other than Bone Graft
Orbital fractures are one of the most frequent consequences following midfacial trauma. If not treated they can lead to serious optical complications as; double vision (diplopia), restriction of ocular motility, enophthalmos. Autogenic bone graft although still wide and effectively used for reconstruction of fractured orbital wall present some disadvantages such as morbidity of donor site, resorption, time consuming procedure and long post-operative care. Because of that introduction of new materials for orbital reconstruction seems to be desirable.
Biocompatible Materials for Orbital Wall Reconstruction—An Overview
Materials, 2022
The reconstruction of an orbit after complex craniofacial fractures can be extremely demanding. For satisfactory functional and aesthetic results, it is necessary to restore the orbital walls and the craniofacial skeleton using various types of materials. The reconstruction materials can be divided into autografts (bone or cartilage tissue) or allografts (metals, ceramics, or plastic materials, and combinations of these materials). Over time, different types of materials have been used, considering characteristics such as their stability, biocompatibility, cost, safety, and intraoperative flexibility. Although the ideal material for orbital reconstruction could not be unanimously identified, much progress has been achieved in recent years. In this article, we summarise the advantages and disadvantages of each category of reconstruction materials. We also provide an update on improvements in material properties through various modern processing techniques. Good results in reconstruct...

Posttraumatic orbital reconstruction has been a challenging mission for decades in craniomaxillofacial surgery. Complications like enophthalmos, diplopia and gaze obstacles emerge when orbital trauma occurs, affecting people's daily life as well as their appearance. Advances in technology and research gained through years of experience has provided us with a greater understanding of the changes following trauma, as well as providing us with a variety of filling materials that we can choose from to handle the deformities. However, the best type of material for repair of orbital deformities remains controversial. This paper reviewed approximately 60 articles discussing materials used in orbital reconstruction or soft tissue defect filling in the past years, with the aim of giving a comprehensive overview of the advantages and disadvantages of materials used in this field so as to help surgeons to make a better choice.
Autogenous Grafts for Orbital Floor Reconstruction: A review
International Journal of Oral and Craniofacial Science, 2017
Orbital fractures are relatively common midfacial injuries encountered in urban areas. Patients usually are seen with periorbitaloedema and restricted eye movements with or without changes in vision. A wide range of autogenous materials can be used in the reconstruction of orbital defects including bone grafts, cartilages and fascia each having its own strengths and weaknesses. The purpose of this paper is to provide a systematic literature review on various autogenous materials used for orbital fl oor reconstruction.

INTRODUCTION: Orbital floor fracture is one of the most common maxillofacial fracture. Hence, many clinical methods were implemented for improvement of the techniques used in treating orbital floor fractures. Poly ether ether ketone had been widely used in reconstruction field due to its superb compatibility and proper mechanical properties. AIM OF THIS STUDY: To evaluate the clinical efficacy and radiographic performance of customized PEEK implant in the treatment of patients with orbital floor fracture. MATERIALS AND METHODS: 9 patients with recent orbital floor fracture were selected. All patients were treated using customized PEEK implants in orbital floor reconstruction. Patients were evaluated after 24-hours, one, four and six weeks for enophthalmos, diplopia, ocular motility and infraorbital nerve function in comparison with preoperative status. In addition, a radiographic investigation was performed immediately to confirm the proper placement of the implant and complete release of orbital soft tissue from the maxillary sinus. RESULT: the study was conducted on seven patients with ZMC fracture and 2 patients with blow-out fracture. None of the enrolled patients showed postoperative diplopia. Six out of the enrolled nine patients in this study reported a subjective abnormal sensation in the course of the affected infraorbital nerve at the first follow-up period. However, all patients regained normal sensation by the end of the follow-up period. The difference of the rate of postoperative ocular complications was statistically significant over the follow-up periods (p=0.036). CONCLUSION: The favorable clinical performance of the patient-specific PEEK sheet in the management of orbital floor defects makes it an exemplary reconstructive alternative with superb compatibility, great surgical precision and predictability.
Repair of Orbital Floor Fractures: Our Experience and New Technical Findings
Craniomaxillofacial Trauma and Reconstruction, 2010
We report our experience with the repair of the orbital floor fractures and present new technical findings. We evaluated 30 subjects with pure blowout fractures treated at the Department of Maxillofacial Surgery of the Federico II University of Naples, Italy, between 2005 and 2007. A preoperative examination by computed tomography scans provided classification of the orbital floor fractures into small and large fractures by measurement of the bone defect to choose the appropriate reconstructive implant materials, resorbable or nonresorbable. The clinical follow-up has been performed at 1 week, 1 month, 3 months, and 6 months. We observed a resolution of preoperative symptoms. The scar was not evident, and there was an absence of postoperative complications. We concluded that the use of resorbable materials for small orbital floor fractures and nonresorbable materials for large orbital floor fractures offers satisfactory results in both functional and aesthetic considerations. Furthermore, the new technical findings allow standardization of the surgical technique to be more accurate, also reducing the economic costs.
