3D Printing in Facial Reconstructionkprokop
The orbit is the cavity or socket of the skull in which the eye and its appendages are situated. It serves as a skeleton for the protective apparatus of the eyeball. Among most common reasons for its injuries are traffic accidents, assault and battery, sports and fall injuries. Out of four walls constituting the eye socket the bottom one gets most commonly damaged. Any injuries of the eye socket can lead to permanent facial deformation and visual impairment, therefore, the correct diagnosis and the right therapeutic decisions are immensely important.
During a traditional surgical procedure the eye socket is stabilized with an appropriately prepared titanium plate which is shaped during the operation. It significantly lengthens the time of procedure and increases the possibility of complications.
The use of modern technologies, including 3D Printing, allows of reducing procedure time and lowering the risk of complications. In preparation for the operation a surgical team uses CT scans to create and print a symmetrical 3D model of the healthy eye socket. The titanium plate is sized and shaped based on the model before the procedure.
3D Printing can also be used when preparing tibial trials. Such trials are often used in the procedures of filling defects in the mandible (jawbone). A CT scan and a 3D model are prepared based on a mirror image of the healthy mandible. The missing part of the mandible is created with the use of appropriate software and then 3D Printed. The missing fragment of the tibia is formed based on the 3D Print and later implanted in the patient’s leg.
