Discovery of a more attractive V-line

# Square Jaw Reduction

An omniangularly attractive jawline

01 A V-line is a mere idea:
it must not be standardized.

Having a V-line has become a necessary element of an attractive facial shape: what is its appeal?

It is due to the proportionate aesthetics that a narrower jaw has over a wide jaw.
A smooth jawline even gives a person’s smile a more refined look.
From this, we may say that the essence of a square jaw reduction is constructing a proportionate and refined jawline.


It is futile to give everyone an identical V-shaped jawline.
Once we understand the essence of a square jaw reduction,
it is possible to surgically uncover a more attractive V-line for every individual patient. It is further possible to design a jawline that shines from many angles, rather than simply having
a V-shape when viewed from the front.

A BANOBAGI V-line is a refined V-line that forms a beautiful curve at all angles, from where the jaw starts to its end.

02 It is
more effective
to make the enhancement through a single surgery .

A jaw surgery is commonly done by sectioning the jaw (e.g. the sides, the front, etc.) for the surgeon’s convenience. For example, a squared jaw is reduced by contouring the rugged ends on the sides, and a thick chin is treated by bringing out the edge. What is overlooked in such procedures is that a human jawline does not only consist of a single jawbone but also is three-dimensional. This make it more viable to operate on both the sides and the front of the jaw at the same time, which results in a more proportionate and inconspicuous results.


Such procedure is neither simple nor easy:
it requires the surgeon to operate swiftly on both the front and the sides without putting stress on the patient.

Square jaw reduction with a natural and beautiful results:

03 Finding the right solution in a procedure
that covers all types tissues.

Masseter muscle, Buccal fat, Jawbone Masseter muscle, Buccal fat, Jawbone

In general, a larger jawbone is accompanied by a muscle of a matching size; and a fleshy face tends to have well developed subcutaneous and buccal fat underneath. For patients with such concerns, a square jaw correction that simply cuts away the jawbone is ineffective.
It is better to take a more comprehensive approach that includes various facial tissues such as the muscle and the fat.
Such complex diagnosis and operation naturally covers the entirety of the facial curve, and it requires a knowledgeable medical team for a satisfying result.


    —since its founding in 2000—has grown into a medical institution with a systematic infrastructure, in which specialists from different fields gather, research and operate on a given medical issue.

    BANOBAGI’s square jaw reduction is a product of a deliberation on facial bones and tissues among facial contouring specialists.

    As a result, a comprehensive method of square jaw reduction has been perfected: ranging from mandibular osteotomy, masseter muscle reduction and cortical osteotomy to buccal fat removal.

  • plus Mandibular osteotomy

    The angled section of the jaw below the ear is commonly referred to as a “square jaw” or the mandibular angle. An excessively developed mandible makes the jawline beefy, and gives the face an unnaturally rugged look.

    The mandibular osteotomy smoothly shaves the mandibular bone and thins it, resulting in a natural curve when seen from both the front and the side; it also slims and smooths downs the facial curve towards the chin.

  • plus Masseter muscle reduction

    A firm and deep-rooted flesh can be felt when pressing down the jaw area right below the ear: this is the masseter, a muscle that is a part of the system that help us chew, but also a cause of a protruded square jaw when excessively developed.

    Botox gives the muscle a temporary reduction, but surgically removing the excess part at the time of a square jaw reduction gives a permanent result and a greater satisfaction.

  • plus Cortical osteotomy

    The facial bone consists of three layers: the outer cortical bone, the cancellous bone, and the inner cortical bone. Cortical osteotomy thinly shaves off the outer cortical bone, and can offer a safe and effective jawline improvement if operated by an experienced specialist.

  • plus Buccal fat removal

    There are two layers of facial fat: a thin and singular layer of subcutaneous fat just underneath the skin, and the buccal fat that lies deep within the cheek. Liposuction is used for the subcutaneous fat, but removing the buccal fat requires an excision through the insides of the mouth.
