What this paper says

In 10 cadaver heads photographed by a fixed camera, a 4 mm lateral crural steal rotated the tip up by a mean 13.2 degrees and shortened the nose by 1.3 mm, but its effect on absolute tip projection varied from a 1.0 mm loss to a 0.6 mm gain.

Overview

Predicting what a tip maneuver will do to projection, rotation and length is a central problem in rhinoplasty. Patient photographs suffer from head position changes and computer models do not match real tissue. The authors fixed cadaver heads and a camera in place so each surgical step could be measured precisely, and used the setup to test the lateral crural steal.

Sections of note

Cadaveric study, 10 specimens, tertiary hospital.
Heads fixed in a Mayfield holder; 12.2-megapixel camera on a fixed tripod focused on the surgical field throughout.
External (open) rhinoplasty approach; 4 mm lateral crural steal performed in each.
Outcomes: tip projection, tip rotation and nasal length from before and after photographs.
Projection by Goode ratio increased by a mean 0.05 (P = .005); rotation increased by a mean 13.2 degrees (P = .005).
Absolute projection change inconsistent: -1.0 mm to 0.6 mm.
Nasal length shortened in all cases, mean 1.3 mm (P = .005).

What it means for a patient

The lateral crural steal reliably lifts and shortens the tip, but whether it makes the tip project more is unpredictable.
Surgeons planning to add projection with this maneuver may need another technique to guarantee it.
Cadaver tissue lacks healing and muscle tone, so living results may differ; 10 specimens is a small sample.

Why this paper matters

It introduces a reproducible way to measure tip maneuvers on cadavers and immediately overturns the assumption that the lateral crural steal adds projection. The method can be applied to other maneuvers.

Terms

Lateral crural steal: moving part of the tip cartilage's side arm into the columella to lift and project the tip.
Tip projection: how far the tip stands out from the face.
Tip rotation: how far the tip points up or down.
Goode ratio: tip projection divided by nasal length, a standard proportion measure.
Mayfield head holder: a clamp that fixes the head rigidly in position.
External rhinoplasty approach: open rhinoplasty through a small cut across the columella.

From the abstract

“The prediction of nasal tip position in terms of projection, rotation, and length is a major challenge in rhinoplasty. Studies using preoperative and postoperative photographs lack accuracy owing to variable position, and computer-simulated models lack clinical applicability. Objectives: (1) To describe an accurate…”
