Morphing of the Frontal View: Rhinoplasty as a Surface Contour Operation

Overview

Simulating the front view before surgery is harder than the profile, since the front view is read through light and shadow rather than outline. Chiaroscuro is a painting technique of dark and light contrast, and the authors apply it to explain possible results. They term the light and shade differences across the side walls, the bridge, the brow dome line and the nose to cheek line the chiaroscuro of the nose.

Sections of note

• Design: case series describing a consultation method, 126 patients operated in 2019.
• Consultations were staged: first visit for history, desires, examination and photography; second visit for photo analysis and a simulated correction made in Adobe Photoshop.
• Age range 15 to 59 years. 84 patients, 67 percent, were women and 42 men. 54 cases, 43 percent, were revisions.
• At postoperative visits, all patients were more satisfied with their result than with the simulation.
• The authors describe the concept as a logical tool for creating a realistic surgical plan, and suggest morphing may help teach young surgeons.

What it means for a patient

• The front view of a nose is defined by shadows along its sides rather than by a silhouette, which is why simulating it requires a different approach from the profile.
• A simulation is a discussion tool. Here, every patient preferred the real result to the picture they were shown.
• Setting the simulation slightly conservative reduces the risk of promising more than surgery delivers, which the reported satisfaction pattern is consistent with.
• Limits: 126 patients, single practice, satisfaction reported as universal without a scoring tool, and no comparison against consultation without simulation.

Why this paper matters

Mismatched expectations drive much of the dissatisfaction after rhinoplasty, and simulation is the main tool for aligning them. Most attention has gone to the profile, leaving the front view poorly handled. Whether this method improves measured satisfaction over standard consultation is untested.

Terms

• Morphing: digitally altering a photograph to simulate a possible surgical result.
• Chiaroscuro: a painting technique using contrast between light and shadow to suggest form.
• Frontal view: the face seen straight on, as opposed to in profile.
• Dorsal aesthetic lines: the shadow lines running from the brows down each side of the bridge.
• Revision case: an operation performed to correct the result of an earlier one.
