orbital floor fracture repair

3-6 Surgical repair of the blowout fracture includes the. Medial orbital wall fractures are known to occur concomitantly with floor fractures.

Right Orbital Floor And Medial Wall Fractures With Surgical Implant Repair

1 mobilize obviously entrapped extraocular muscles in cases presenting with positive forced ductions and severe subjective diplopia 2 mobilize a large volume of herniated orbital fat back into the orbit in order to return the globe to its preinjury location in cases where greater than 2mm of enophthalmos and or.

. There was also a significant mean increase in IOP of 744 mmHg p 005 at postoperative day 1 compared with immediately after implant. Titanium meshes and bone grafts are radiopaque. Some orbital floor fractures may be minor and not require operative treatment.

Nine patients who underwent isolated orbital floor fracture repair were examined. Orbitotomy was performed via standard transconjunctival. Author Yong Jig Lee 1 Affiliation 1 Department of Plastic and Reconstructive.

Orbital fracture is a breakage in the bone in the eye socket which can involve the rim the floor or even both. Timing of orbital floor fracture repair surgery is critical as orbital and cheekbone fractures may heal quickly. There was a statistically significant mean decrease of 466 mmHg p 005 in IOP from prior to surgical to immediately after implant placement.

More commonly titanium meshes porous polyethylene sheets or autologous bone grafts. This video demonstrates repair of a left orbital floor fracture. 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.

A lateral canthotomy is then performed with a 15 blade followed by an inferior cantholysis. Surgical reconstruction should account for the complex curvatures of each wall that combine to form a conoid shape with its apex in the superomedial posterior orbit. Orbital floor fracture repair surgery is most frequently performed with an open technique in which skin incisions or incisions within the lining of the eyelid are necessary.

Some orbital floor fractures may be minor and not require operative treatment. Orbital floor fracture repair surgery is most frequently performed with an open technique in which skin incisions are necessary. The defect is analyzed for size location soft tissue prolapse soft tissue entrapment and bony comminution.

A retrospective study Arch Craniofac Surg. Orbital floor fracture repair with implants. Timing of orbital floor fracture repair surgery is critical as orbital and cheekbone fractures may heal quickly.

Retrospective case series of 4 consecutive patients with trap door orbital wall fractures secondary to blunt trauma with entrapped orbital soft tissue who underwent surgical repair with placement of Sepraﬁlm implant in 2008. An incision was made in the inside of the eyelid during surgery. Forced ductions are checked which are shown to be restricted in supraduction.

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. Treatment for Orbital Fracture comprises of surgery in severe cases and ice packs rest and antibiotics in mild fractures. Alloplastic prostheses should be used but if large or comminuted fractures are involved bone grafting is an interesting first choice.

Orbital wall fracture repair. Early decompression is favorable for neural restitution. 2 Recent clinical studies have recommended prompt surgical repair in patients with large fractures 50 of the orbital floor and in those with disability diplopia or enophthalmos of greater than 2 mm or both 10 to 14 days after trauma.

However titanium meshes add to the cost of the surgery while bone graft requires additional graft donor site. If a trap door injury is encountered with strangulated soft tissue a small portion of mucosa is stripped away from the fracture. Entrapment of the orbital tissue by the placement of an implant.

The only truly modifiable variable was the material used for orbital floor repair. The orbital floor then is inspected with 0 or 30 sinus endoscopes. Depending on the amount and severity of dislocation around the course of the infraorbital nerve decompression might be indicated.

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. 40 silk sutures are placed through the lower eyelid at the level of the tarsus. Most literature supports a 2-week window for repair to prevent fibrosis resulting tissue.

Repair of an orbital floor fracture involves bridging of the floor defect using one of the various biomaterials. To help this and decrease scarring on the inside of the eyelid. This video illustrates the use of porous polyethylene implant stabilized with cyanoacrylate glue to repair an orbital floor fracture by the transconjunctival.

Postoperative instructions following Orbital Fracture Repair Surgery. The timing and requirements for surgical repair of pure orbital floor fractures has been long debated. Therefore some irritation and foreign body sensation in the eye is normal.

Incomplete removal of extraocular muscles and associated orbital tissues from the fracture site prior to implant. The repair of orbital fractures involves fracture site exposure freeing tissue prolapsed into the fracture site and reapproximating the orbital wall support usually with an implant. Reconstruction of the orbital floor has to respect the course of the infraorbital nerve in the orbital floor.

There are several reasons to repair blowout fractures. Epub 2021 Aug 20. Orbital Floor Fractures Section V.

Patients suspected of suffering an orbital floor fracture should undergo thin cut 10 - 15mm axial CT scans of the orbit with coronal reconstruction Thin cut coronal reconstructions are actually preferred to direct coronal images as they avoid artifact from dental amalgam.
