Reconstruction Of Orbital Floor Defects Research Articles

A simple template for orbital floor defects

Proper reconstruction of orbital floor defects is paramount in the restoration of globe position and function. To reconstruct the orbital floor, the chosen material must be sized and shaped to cover the defect and be supported by the remaining bony floor. This can become time-consuming, and the implant may become dislodged if not of adequate size and shape, resulting in enophthalmus and the possible need for reoperation. In an attempt to create a more anatomically accurate and supportive orbital floor graft, a simple template from the outer covering of a suture packet was devised.

Experimental evaluation of expanded polytetrafluoroethylene for reconstruction of orbital floor defects

Objective : This study evaluates the efficacy of a medical grade expanded polytetrafluoroethylene (e-PTFE) sheet for reconstruction of the orbital floor. Materials and Methods : Orbital floor defects were created in 10 domestic sheep and reconstructed with the 1-mm thick e-PTFE sheet. The surgical sites were evaluated for the development of enophthalmos and biocompatbility at 2 weeks, and at 1-, 2-, 4-, and 6-month intervals. Results : The results of this study indicate that the e-PTFE material has excellent handling characteristics, provides stability to correct surgically created enophthalmos, and causes essentially no foreign body reaction. Conclusion : Expanded polytetrafluoroethylene proved to be an excellent alloplastic material for the repair of orbital floor defects in this experimental study.

The Use of Teflon in Orbital Floor Reconstruction Following Blunt Facial Trauma

A myriad of materials have been used for reestablishing continuity of the orbital floor following blunt facial trauma. Traditionally, autogenous grafts have been the material of choice for orbital floor reconstruction; however, alloplastic materials have gained popularity because of their availability and ease of use. A large clinical experience with long-term treatment results has never been reported for any substance used in orbital floor reconstruction. The purpose of this study was to review our long-term treatment results using Teflon for orbital floor reconstruction following blunt trauma, with emphasis on the incidence of infection, extrusion, and implant displacement. This report presents a 20-year review of 230 Teflon implants for reconstruction of traumatic orbital floor defects. With a mean follow-up period of 30 months, there was only one implant infection and no complications of extrusion or implant displacement. These findings support the use of Teflon as a safe and effective material for the reconstruction of orbital floor defects following blunt facial trauma.

Reconstruction of orbital defects with autogenous bone from mandibular symphysis

Autotransplant bone is superior to other bone, cartilage, or alloplastic materials for the reconstruction of orbital floor defects. The bone used for filling orbital floor defects is taken from the symphysis of the lower jaw. The piece of bone, up to 3.5 X 1.5 cm in diameter is strong enough to support the orbital contents, while at the same time it is easily modelled and positioned. This method is indicated for reconstruction of the orbital floor, with or without rim defects. Taking of the transplant, while retaining the lower margin of the mandibular symphysis, preserves the contour of the chin.
