Ct Scan Orbital Floor Plate

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.

Ct scan orbital floor plate.

We then cover the implant with our proven medpor biomaterial to minimize sharp edges even if the plate requires modification. Functional endoscopic sinus surgery was performed to drain the maxillary mucocele and 50 ml of thick yellow mucus was expressed which was sent to pathology. The arrow indicates the buttress of the transition zone between medial orbital wall and orbital floor. Coronal slice of a ct scan shows a non affected left orbit with normal anatomy of the transition zone.

3d orbital floor inlay designed to hold small and large left and right 3d orbital floor plates sits beneath standard inlay within the small. Large fracture 50 of orbital floor on ct scan indicates that enophthalmos is likely to occur. This is typically caused by a direct blow to the central orbit from a fist or ball. Coronal slice of a postoperative ct scan taken after transconjunctival repair of the complete left medial orbital wall and orbital floor.

Universal 1 2 upper face module laser etched to aid in plate identification plate holding forcep plate holding forceps utilizes two pins to stabilize plate. The following discussion assumes a volume ct technique using a multidetector scanner when referring to ct. Orbital floor fracture repair might be indicated in this setting for small or medium sized defects. A coronal ct scan of a left maxillary mucocele eroding through the orbital floor and medial antral wall.

Concomitant medial orbital wall fracture can increase risk of progressive enophthalmos. Computed tomography ct is the primary modality for assessing orbital soft tissue and bony injury in the emergency setting. Materials such as silicone and pmma have been in use for over 30 years and are radiopaque fig 11. We use ct scan data to design the titantium implants to approximate the anatomy of the orbital floor and medial wall.

Appropriate timing is based on the clinical exam and imaging. 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. Orbital blowout fractures occur when there is a fracture of one of the walls of orbit but the orbital rim remains intact. Epidemiology the blowout fracture is t.

Ct scanning of the orbits is very quick which significantly reduces motion artifacts.
