Figure 3 :Schematic illustration of our algorithm to select the optimal choice of surgical approach. The relative position of the lesion to a line drawn from the hard palate to the posterior pharynx (the nasopalatal line) dictates the choice of approach. Lesions are defined as types A (well above NP line), B (intermediate location above the NP line), or C (at or below NP line). Left (Type A): For lesions located well above the hard palate, an endoscopic transnasal approach is optimal. Middle (Type B): For intermediately located compressive lesions of the craniovertebral junction that protrude above the hard palate, either a transnasal or a transoral endoscopic route may be used. Also, we found that a combination of both approaches was often quite helpful. Right (Type C): For lesions located at the level of the hard palate (or below) a standard open, transoral approach is preferred
