Ct Scan Orbital Floor Plate

Orbital floor fracture repair might be indicated in this setting for small or medium sized defects.

Ct scan orbital floor plate.

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. Coronal slice of a ct scan shows a non affected left orbit with normal anatomy of the transition zone. We then cover the implant with our proven medpor biomaterial to minimize sharp edges even if the plate requires modification. 3d orbital floor inlay designed to hold small and large left and right 3d orbital floor plates sits beneath standard inlay within the small.

Computed tomography ct is the primary modality for assessing orbital soft tissue and bony injury in the emergency setting. 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. This is typically caused by a direct blow to the central orbit from a fist or ball. The arrow indicates the buttress of the transition zone between medial orbital wall and orbital floor.

The following discussion assumes a volume ct technique using a multidetector scanner when referring to ct. Coronal slice of a postoperative ct scan taken after transconjunctival repair of the complete left medial orbital wall and orbital floor. Large fracture 50 of orbital floor on ct scan indicates that enophthalmos is likely to occur. We use ct scan data to design the titantium implants to approximate the anatomy of the orbital floor and medial wall.

Orbital implants have a variable appearance at ct depending on their composition. Concomitant medial orbital wall fracture can increase risk of progressive enophthalmos. Orbital blowout fractures occur when there is a fracture of one of the walls of orbit but the orbital rim remains intact. A coronal ct scan of a left maxillary mucocele eroding through the orbital floor and medial antral wall.

The matrixmidface preformed orbital plates are designed from ct scan data. Materials such as silicone and pmma have been in use for over 30 years and are radiopaque fig 11. Epidemiology the blowout fracture is t. Appropriate timing is based on the clinical exam and imaging.
