Upper Facial Height Nasal Height

Definition Distance from the root of the nose (nasion) to the base of the nose (subnasion).

Landmarks Measure from the deepest part of the nasal root (nasion) to the deepest point of concavity at the base of the nose (subnasion), in a vertical plane (Figs 7.1 and 7.13).

Instruments Sliding calipers are most accurate. A tape-measure could be used, avoiding the natural curve of the midface.

Position Frankfort horizontal, with the facial profile in the vertical.

Alternative If the nasal tip is long or pointed down, masking the subnasion, this measurement is best taken from the side.

Remarks Upper facial height corresponds to nasal height (Fig. 7.14).

Pitfalls A prominent nasal bridge may distort the position of the nasion and produce a less accurate measurement.
