Figure 6. Lateral view of the nasal septum depicting the mucosal cut made for elevating a nasoseptal flap (dashed line) during an endoscopic transtuberculum/transplanum approach, preserving olfaction by sparing the septal olfactory strip above which contains the olfactory nerve fibers. A rescue flap incision (solid line) is made on the other side, again aimed at preserving olfaction.
