Abstract

Purpose

The advantages of rigid fixation over wire osteosynthesis are well established for the management of facial trauma. Miniplates in the frontozygomatic area are traditionally applied to the lateral face of the orbital rim, but with some undesirable effects, such as palpability, visibility, and risk of penetration into the anterior cranial fossa. The aim of this study was to perform an anatomical study to validate the use of miniplates on the temporal face of the frontozygomatic region.

Methods

Osseous thickness measurements were performed in 30 skulls, on four points above and four below the suture, at 3-mm intervals, perpendicular to the bone surface.

Results

There is enough bone thickness to apply the screws, ranging between 4 and 6.5 mm. The first hole over the frontozygomatic suture should receive the smallest screws and the other areas can receive screws up to 6 mm. All drillings are made from the temporal fossa to the orbit, and its contents should therefore be protected during the perforations. At the measured points there is no risk of anterior cranial fossa penetration.

Conclusion

This study suggests that it is possible to use miniplates at the temporal aspect of the frontozygomatic suture.
