Photogrammetric analysis of soft tissue facial profile in Turkish rhinoplasty population

Overview

Which facial measurements push people to seek rhinoplasty? The authors compared photographs of Turkish rhinoplasty patients with photographs of Turkish people who had no nasal deformity and were satisfied with their appearance, using facial analysis software to measure angles and proportions.

Sections of note

• 40 rhinoplasty patients (20 men, 20 women) and 40 controls without nasal deformity (20 men, 20 women).
• Rhinobase software used for photogrammetric analysis of facial photographs.
• Significant differences (P < 0.05) between patients and controls, and between men and women, in nasofrontal angle, nasolabial angle, chin projection, middle facial height and tip deviation angle.
• Patients showed a crooked nose, an obtuse nasofrontal angle, an acute nasolabial angle, chin underprojection and increased middle facial height.
• The abstract gives no mean values for the measurements.

What it means for a patient

• Features other than the nose, notably a receding chin and a long midface, were more common in people seeking rhinoplasty in this sample.
• A surgeon may look at chin and facial proportions when planning a nose operation.
• Small sample from one population; norms for other ethnic groups may differ, and the abstract lists no measurement values.

Why this paper matters

Facial norms drive rhinoplasty planning, and most published norms come from Western populations. This study adds population-specific data for Turkey and links specific measurements to the decision to seek surgery. Whether correcting these measurements improves satisfaction is not tested.

Terms

• Photogrammetry: taking measurements from standardized photographs.
• Nasofrontal angle: the angle between the forehead and the bridge at the root of the nose.
• Nasolabial angle: the angle between the columella and the upper lip, a measure of tip rotation.
• Chin projection: how far the chin stands forward in profile.
• Middle facial height: the vertical distance across the middle third of the face.
• Tip deviation angle: how far the nasal tip sits off the facial midline.
