Dex·الثلث السفلي للوجه
Mentolabial angle
كانون المجتمع
The crease between lower lip and chin. The community treats a moderate, defined crease as a marker of strong chin projection and masculine bone structure. Very deep creases get penalized as recessive chin tells. Flat angles get flagged as soft, undefined or post-filler.
الكانون الطبي
Photographic aesthetic studies converge on 107 to 118 degrees as the most attractive range, with acceptability extending to about 140. Below 100 degrees signals strong chin protrusion or hyperactive mentalis. Above 145 indicates retrusion or soft-tissue excess.

طريقة القياس
Lateral photo. Mark the labrale inferius (lowest point of the lower lip vermillion), the deepest point of the labiomental sulcus, and the pogonion. The angle at the sulcus is the mentolabial angle.
الأثر الإدراكي
A balanced crease defines the chin pad without hollowing it. Too deep reads severe and aging. Too shallow reads underdefined or filler-flat.
مسارات التحسين
Filler in the labiomental sulcus softens deep creases. Botox into hyperactive mentalis muscles relaxes peau d'orange chin. Chin implants or genioplasty reshape the underlying skeletal angle.
