Nasal Height

Definition The distance from the nasal root (nasion) to the nasal base (subnasion).

Landmarks Measure from the deepest depression at the root of the nose to the deepest concavity at the base of the nose, in a vertical axis (Fig. 7.66).

Instruments Spreading calipers are most accurate. A tape-measure could be used if held straight in a vertical plane, avoiding the contours of the face.

Position Frankfort horizontal, with the facial profile in the vertical. The patient can be observed from the front or from the side.

Remarks Nasal height is the same as upper facial height, which has been documented in a previous section (Fig. 7.67).

Pitfalls If the nasal root is high with a prominent nasal bridge, the actual position of the nasion may be difficult to place. If the nasal tip is pointed, long, and overhangs the upper lip, then the position of the subnasion may be difficult to place, particularly from an anterior view.
