FTOZ- Model 5

Model 5: Volumetric model of the six bone cuts involved in the two-piece frontotemporal-orbitozygomatic craniotomy. The first cut is made across the posterior root of the zygomatic arch (blue line). The second cut is made at the inferolateral margin of the zygomatic bone (sky blue line). The third cut is initiated in the anterolateral portion of IOF and extends posterolaterally to join the second cut above the malar eminence (orange line). The fourth cut is made perpendicular to the superior orbital rim and extends posteriorly across the orbital roof toward SOF (red line). The fifth and sixth cuts are made starting from IOF (purple line) and SOF (green line), respectively, to join these structures and ultimately elevate the orbitozygomatic bone flap.
