Ct Scan Obital Floor Plate

These plates consist of implants that closely approximate the topographical anatomy of the human orbital floor and medial wall and are intended for use in a selective craniomaxillofacial trauma.

Ct scan obital floor plate. The overlying colored line in the medial wall and orbital floor area indicate the preoperative virtual planning that is superimposed on the mesh reconstructed area. Coronal slice of a postoperative ct scan taken after transconjunctival repair of the complete left medial orbital wall and orbital floor. Plate borders medial wall orbital floor designed from ct scan data the three dimensional implants closely approximate the topographical anatomy of the hu man orbital floor and medial wall to provide accurate recon struction even after significant two wall fractures 5 6 preformed three dimensional shape. This x ray shows the classic transition zone.

Coronal ct shows ablation of the greater wing of the sphenoid bone od with herniation of the temporal lobe into the orbit causing hypoglobus and pulsatile proptosis. A 3 d ct of unilateral clinical anophthalmia with hypoplasia of the ipsilateral bone. The floor is likely to collapse because the bones of the roof and lateral walls are robust. 54 04005 3d orbital floor plate right large 54 04006 3d orbital floor plate left small 54 04007 3d orbital floor plate left large storage.

Stryker craniomaxillofacial kalamazoo mi 49002 usa. The follow up time was 9 to 45 months mean 20 4 months. Radiographic analysis showed that in 12 of the 13 patients there was new bone in the orbital floor. A ct scan was obtained in 13 patients.

We use ct scan data to design the titantium implants to approximate the anatomy of the orbital floor and medial wall. The ophthalmologist will check to see if the eye moves as it should and if there are any vision problems. Epidemiology the blowout fracture is t. An orbital blowout fracture is a traumatic deformity of the orbital floor or medial wall typically resulting from impact of a blunt object larger than the orbital aperture or eye socket most commonly the inferior orbital wall i e.

The matrixmidface preformed orbital plates are designed from ct scan data. We then cover the implant with our proven medpor biomaterial to minimize sharp edges even if the plate requires modification. The use of a polydioxanone pds plate for orbital reconstruction was evaluated in 20 patients with various traumatic defects of the orbital floor. This is typically caused by a direct blow to the central orbit from a fist or ball.

Orbital blowout fractures occur when there is a fracture of one of the walls of orbit but the orbital rim remains intact.
