Nasal Tip Projection: Goode Ratio, Landmarks, and Profile Balance

Nasal tip projection describes how far the tip extends forward relative to a specified facial or nasal reference. It differs from nasal length and tip rotation. The Goode ratio compares a projection distance with nasal length; other methods use different lines. Name the method before comparing values, because a similar-looking fraction can represent a different construction.

On a side profile, mark the nasal tip, nasal root and the alar-facial reference required by the chosen method. For the Goode construction, use the defined facial reference line to obtain tip projection and divide it by the defined root-to-tip nasal length. Save the traced lines with the ratio.

An illustrative projection of 30 units divided by a nasal length of 50 units gives 0.60. It is only a calculation example. Changing the reference line or denominator changes what the ratio means.

Record tip rotation separately. A tip can move upward and change its apparent projection or nasal length at the same time.

Projection is relative to the reference face and nose. A tip may look prominent beside a less projecting chin, or appear less prominent beside a higher bridge, without having moved.

Compare the nasofrontal angle, nasomental angle and facial convexity to separate the surrounding relationships.

A retrospective study of 173 operations found that a columellar strut did not significantly change projection or rotation when upward rotation was not intended. Surgical intent and accompanying steps mattered (PMID 32062744).

A 20-patient case series found increased upper-lip projection in 18 patients after procedures intended to increase tip projection. The small selected series supports examining adjacent features; it does not prove the same effect for every procedure (PMID 28418453).

A 106-patient comparison found different maintenance of rotation between graft techniques, but no significant between-group difference in projection change over time. Projection and rotation are separate outcomes (PMID 31373990).

Anthropometry in 500 young ethnic Kazakhs reported a mean Goode projection index of 57.25%. This is a sample reference under that study method, not a required proportion (PMID 27500583).

A study using nasal composites found that nasion position and dorsal contour influenced perceived nasal shape. A ratio alone leaves out those visible features (PMID 18300984).

Keep the camera well back and use framing that preserves a true side profile. Moving a camera close to the nose changes perspective; cropping the resulting image cannot undo it.

Match camera distance and head orientation across sessions. Take multiple images and redraw the reference line independently to see how much the ratio varies with placement.

Shastra estimates visible nasal and facial geometry. Confirm the construction behind an output before comparing it with a Goode ratio from a paper.

A surface image cannot reveal cartilage support or establish the result of an operation. Use the estimate to describe the profile and inspect its components.

A projection report should identify the reference line, nasal length definition and ratio, with rotation listed separately. That gives more information than calling a nose overprojected from a close selfie.
