Figure 3: (a) Endoscopic view onto bone flap extended to a transplanum approach with all incisions performed, the sellar bone flap has. (b) Transplanum bone flap tilted inferiorly, a thinned out bone bridge was left at the inferior left corner to act as a door swing. (c) The transplanar bone flap is removed and a measuring scale was put as an “underlay” epidurally to visualize the size of the flap. (d) Both bone flaps are repositioned in the sella and sphenoidal plane, respectively.
