VIP International Plastic Surgery Center in KOREA - Jawline Reduction

Cephalometry (life-size X-ray of face) analysis
Application of Jaw Reduction
Square-shaped face due to the prominent gonial angles
Large chin and big face in frontal view
Short-looking neck due to the prominent mandible
Vertically short and horizontally wide chin
Aesthetics in frontal view
The distance between the gonial angles is
the same as the distance between the temples
and 10% less than the distance between
the cheekbones.
Oblique view
The forward curve below the ear should be natural.
Ideal angle of the chin
The gonial angle is 105° - 115° and
the angle between the cranial base
and the chin is 300°.
Function and anatomy of the chin

As the inferior alveolar bone nerve, which is responsible for the sensing of lower teeth and lips, traverses the inside of chinbone, an X-ray should be taken before the surgery to observe where the nerves are located and decide how much to resect the bone according to the run direction and height of nerves.

As there are many big vessels around the chin, the procedure requires a careful detachment and hemostasis. As many facial nerve branches are located in each area of the chin, attention should be placed on the choice of incision and procedure, especially in the joint area of the chin in order to prevent damage.

Relationship with the masticatory muscle

In many square jaw cases, not only the bone but also the masticatory muscle is thickened.
When the angular part of the bone is resected, the masticatory muscle attached to the bone gets also recessed accordingly.
However, in excessive development of the masticatory muscle,
it is desirable to simultaneously resect a part of the masticatory muscle in order to obtain a more effective result.

Recently, in order to more effectively and conveniently reduce this muscle, the injection of Botox into the masticatory muscle during the surgery is preferred to the direct resection of the masticatory muscle.
