Superolateral orbital rim

Approaches to the superolateral orbital rim

Access area

The lateral eyebrow approach gives rather limited access to zygomaticofrontal process and the immediate vicinity of suture line (superolateral orbital rim).
The brow skin is thick and the wound edges are not very yielding to retraction but the overall skin mobility allows the shifting of the wound pocket over the bony surface, thus somewhat increasing the field of exposure by varying the traction vector. The entry into the superolateral internal orbit is very restricted and it is difficult to gain much exposure of the sphenozygomatic suture line. A lateral extension of the incision outside the brow to widen the approach will cause conspicuous scarring. Inferior extensions will cross the relaxed skin tension lines (RSTL).
