The PCF was introduced into the nose through the uppermost portion of the frontal sinus (money box approach). Computed tomography (CT) scans (n = 50) were used to measure the dimensions of the PCF and the skull base defects.

Using CT scans, we determined that to reconstruct defects secondary to transcribriform, transtuberculum, clival, and craniovertebral approaches, the PCF distal incision must be placed respectively at \u22123.7 \u00b1 2.0 cm (angle \u221217.4 \u00b1 8.5\u00b0), \u22120.2 \u00b1 2.0 cm (angle \u22121.0 \u00b1 9.3\u00b0), +5.5 \u00b1 2.3 cm (angle +24.4 \u00b1 9.7\u00b0), +8.4 \u00b1 2.4 cm (angle +36.6 \u00b1 11.5\u00b0), as related to the reference point.
