An incision was made in the inside of the eyelid during surgery. The timing and requirements for surgical repair of pure orbital floor fractures has been long debated. Khalifehs preferred approach for fixing orbital floor defects is the transconjunctival approach.
In this retrospective study of 58 patients 36 eyes repaired within 14 days mean of 9 days were compared with 22 eyes repaired at up to 29 days mean of 19 days. Any entrapped orbital tissues should be freed from the fracture site at the time of surgery releasing any mechanical strabismus which should be verified at the end of surgery with forced. Timing of orbital floor fracture repair surgery is critical as orbital and cheekbone fractures may heal quickly.
Alloplastic prostheses should be used but if large or comminuted fractures are involved bone grafting is an interesting first choice. However titanium meshes add to the cost of the surgery while bone graft requires additional graft donor site. The floor of the eye socket ruptures or cracks resulting in a small hole in the eye sockets floor which can trap some parts of the eye muscles and its surrounding.
Generally an orbital floor defect larger than 50 or 2 cm 2 is indicated for a surgical correction. Illustration depicting the left bony orbit. Orbital Fracture Repair Abstract.
The timing and treatment indications for orbital floor fractures are evolving. Reconstruction of the orbital floor has to respect the course of the infraorbital nerve in the orbital floor. Therefore some irritation and foreign body sensation in the eye is normal.
A lateral canthotomy is then performed with a 15 blade followed by an inferior cantholysis. The circular orbit is divided into four walls. Repair of an orbital floor fracture involves bridging of the floor defect using one of the various biomaterials.
Orbital floor fracture repair should restore orbital volume by replacing orbital tissues to their anatomical position within the orbit and reconstructing the orbital bony anatomy. This video demonstrates repair of a left orbital floor fracture. Postoperative instructions following Orbital Fracture Repair Surgery.
A retrospective review was conducted of patients medical charts and initial computed tomography images from 2009 to 2020. The assessment of a patient with a suspected orbital. Orbital floor fracture repair surgery is most frequently performed with an open technique in which skin incisions are necessary.

Notice significant enophthalmos recession of the right eyeball into the maxillary sinus in this young woman who came to the emergency room after a fall. Here is a case study from one of his patients.
The time to treatment. This video illustrates the use of porous polyethylene implant stabilized with cyanoacrylate glue to repair an orbital floor fracture by the transconjunctival. Therefore this study investigated the outcomes of implant surgery for inferior orbital wall fractures by comparing three groups according to the time interval between the injury and surgery.
Most literature supports a 2-week window for repair to prevent fibrosis resulting tissue. The CT scan shows a significant orbital. 40 silk sutures are placed through the lower eyelid at the level of the tarsus.
More commonly titanium meshes porous polyethylene sheets or autologous bone grafts. Can be without clinical evidence of extraocular muscle entrapment OPRS 2009. Variation in presentations both clinically and radiographically complicate prompt diagnosis.
Orbital Floor Fractures Section V. The only truly modifiable variable was the material used for orbital floor repair. Orbital Implants Orbital Implants Autogenous grafts Bone Cartilage Human donor grafts Xenografts Alloplastic implants Porous polyethylene Porous polyethylenetitanium Titanium mesh Polyamide mesh Benefits of alloplastic implants Sizeable to accommodate defect.
Early decompression is favorable for neural restitution. Evaluation of Orbital Fractures. A complete ophthalmic examination is essential for any patient presenting with.

Nonresolving oculocardiac reflex the white-eyed blowout fracture and early enophthalmos or hypoglobus are indications for immediate surgical repair.
Titanium meshes and bone grafts are radiopaque. Forced ductions are checked which are shown to be restricted in supraduction. Appropriate timing is based on the clinical exam and imaging.
To help this and decrease scarring on the inside of the eyelid ointment andor drops MUST be put in the eye 4 times a day until seen in clinic for the post-operative visit.
