- Antitragus: The opposing nub outside the ear canal
- Helix: The outer rim of the ear
- Lobe: The soft lower portion of the ear
Lower Facial Landmarks
The lower third of the face includes several landmarks that define the mouth, chin, and jawline Simple as that..
Mouth and Lips
The mouth is one of the most expressive facial features:
- Vermilion border: The edge between the lip tissue and the surrounding skin
- Philtrum columns: The ridges on either side of the philtrum
- Orbicularis oris: The muscle surrounding the mouth
- Commissures: The corners of the mouth where the upper and lower lips meet
Chin and Jawline
The chin and jawline provide definition to the lower face:
- Mental protuberance: The prominent point of the chin
- Mental tubercles: The rounded bumps on either side of the chin
- Angle of the mandible: The lower back corner of the jaw
- Ramus of the mandible: The vertical portion of the jawbone
Facial Proportions and Symmetry
Facial landmarks are essential for understanding facial proportions and symmetry, which are critical for aesthetic assessment:
- Facial thirds: The face is typically divided into three equal horizontal sections from the hairline to the eyebrows, eyebrows to the base of the nose, and base of the nose to the chin
- Canthal tilt: The angle of the inner and outer corners of the eyes
- Facial width: The distance between the zygomatic arches
- Facial symmetry: The balance between the left and right sides of the face
