Facial Asymmetry
Symptom
When the central line of the face is not straight, we call it facial asymmetry. The jaw line on the right and left are different and the central line is bent or skewed. In some cases, asymmetry of the right and left jaws can occur. In other cases, mandibular prognathism or mouth protrusion can occur on top of facial asymmetry.
Cases
1. The central line of the face is not straight and the patient
- This is a common type of facial asymmetry based on clinical observation.
- Two-jaw surgery is recommended, followed by orthodontic treatment, both of which will improve facial asymmetry.
- In this case, we recommend ID Hospital’s V-line two-jaw surgery.

2. The central line of the face is not straight and the patient has microgenia and mouth protrusion.
- Facial asymmetry is caused by one side or both sides of the jaw bone being under-developed
- The lower chin is pulled forward and facial asymmetry is improved through two-jaw surgery.
- In this case, we recommend ID Hospital’s V-line two-jaw surgery.

3. The lower chin is wide and the patient has facial asymmetry
- The central line and the jaw line are both out of balance and the lower chin is relatively wide.
- Facial asymmetry is improved through two-jaw surgery with mandibular angle reduction surgery.
- In this case, we recommend ID Hospital’s V-line two-jaw surgery.

4. The right and left sides of the jaw line differ in length and angle.
- The central line is straight but the jaw line on each side varies.
- By varying the amount of jaw bone excised on each side, two-jaw surgery with mandibular angle reduction surgery will achieve facial symmetry.
- In this case, we recommend ID Hospital’s V-line two-jaw surgery.
