To avoid unnecessary surgery, the patient type must be accurately diagnosed
Two jaw surgery is a procedure that severs and moves the jawbones themselves. While this makes the surgery effective, it also comes with much pain and lengthy recovery. Therefore, in two jaw surgery, it is important for the surgeon to clearly plan out the course for improvement with the patient and deliver only the necessary procedures. This can be achieved by thoroughly understanding the patient from the consultation/diagnosis stage.
Our facial structure is determined not only by the shape of the bone but also from various elements like fat distribution, muscle, and skin; if two jaw surgery is planned simply from the superficial aspects of the outcome without any in-depth analysis, the patient may be subjected to excessive surgery or require corrective surgeries.

Our thorough diagnosis can identify almost every type and make improvements
Since founded in 2000, BANOBAGI’s facial contouring specialist team has been continuously accumulating knowledge and experience in two jaw surgery. We plan the surgery by understanding your jaw structure and facial expressions—using precision 3D facial CAT scanner and through detailed consultations—and provide safer, more precise surgery by collaborating with anesthesiology specialists and oral and maxillofacial surgeons. This means that we can identify almost every patient type (e.g., short chin, lantern jaw, long face, facial asymmetry, etc.) and provide more accurate and satisfying improvements.

Short Chin Correction
through Two Jaw Surgery
The term “short chin” refers to a state in which the chin is not jutted out enough or even retracted inward.
Short chin comes in two categories: underdevelopment in the chin or an overall lower jaw retracted inward. A simple underdevelopment can be corrected with chin surgery through osteotomy or implant insertion, but if the lower jaw itself is misaligned with the upper jaw, two jaw surgery is needed.

Two Different Types of Short Chin Correction
-
Entire lower jaw retracted inward:
two jaw surgery necessary -
Proper teeth occlusion, but underdeveloped chin: can be corrected through chin surgery
Two jaw surgery for short chin includes teeth alignment.
Two jaw surgery for short chin—caused by an overall lower-jaw retraction—includes teeth occlusion alignment as well. This is why BANOBAGI plans two jaw surgery with a professional teeth alignment in collaboration with oral and maxillofacial specialists.
The surgery accomplishes teeth alignment with orthodontics, and the key is to osteotomize the lower jaw, including the teeth, properly bring it outward, and fix it into position.
Here, BANOBAGI severs the lower jaw in an angle: this increases the attachment area, allowing for more stable and natural fixation between the moved bone and the existing bone. Because the overall lower jaw is moved forward, the chin gains more dimensions, and the jaw-neck border becomes clearer, resulting in a smaller, sharper face.

+ Orthodontic planning in collaboration with oral and maxillofacial specialists
-
+ Osteotomy on lower jaw including the teeth
-
+ Severed lower jaw moved forward according to the orthodontic alignment
-
+ Firmly fixed into place with titanium pin
-
+ Continuous orthodontic treatment and recovery program

Lantern Jaw Correction
through Two Jaw Surgery
“Lantern jaw” is a colloquial reference to a lengthy, prominent chin development.
This is one of the most common facial structure concerns, because of the aesthetic features and many other daily discomforts caused by it (e.g., joint issues, lisping, etc.).
There are many causes behind a lantern jaw, but professionals group them into two categories, depending on the bone structure: one is a simple elongated chin development in which the teeth alignment is normal, and the other is an overall lower-jaw protrusion, including the teeth. The formal can be corrected with an osteotomy in the chin, but the latter requires two jaw surgery.

Methods of Lantern Jaw Correction by Patient Type
-
Overall lower-jaw protrusion, including teeth:
two jaw surgery required -
Normal teeth alignment, but prominent chin development: can be corrected with chin surgery
Two jaw surgery for lantern jaw includes teeth alignment.
Two jaw surgery for lantern jaw—caused by an overall lower-jaw protrusion—includes teeth occlusion alignment as well. This is why BANOBAGI plans Two jaw surgery with a professional teeth alignment in collaboration with oral and maxillofacial specialists.
The surgery accomplishes teeth alignment with orthodontics, and the key is to osteotomize the lower jaw along with the teeth, or both the upper and the lower jaws, properly move it backward, and fix it into position.
Here, BANOBAGI severs the lower jaw in an angle: this increases the attachment area, allowing for more stable and natural fixation between the moved bone and the existing bone. Because the overall lower jaw is moved backward, the two jaw surgery yields effective. Afterward, the remaining unnecessary soft tissue between the neck and the jaw can be removed through liposuction, resulting in a smaller, sharper face.

Long Face Correction
through Two Jaw Surgery
To an ordinary person, a long face appears similar enough to a lantern jaw. However, medically speaking, a long face has a different structure than a lantern jaw, and the corrective measures taken for each type slightly differ as well.
There are many reasons behind a long face development, but the most common are (a) vertical overdevelopment of bone structure behind the upper gums overexposing the gums, (b) malocclusion in the front teeth because of misalignment between the upper and the lower jaws, and (c) simple case of long chin making the face appear elongated.
A simple case of long chin can be corrected with an osteotomy by reducing its length, but all other cases require two jaw surgery.

Methods of Long Face Correction by Patient Type
-
Open bite from malocclusion:
two jaw surgery required -
Long upper-gum bones and elongated lower jaw development: two jaw surgery required
-
Normal teeth alignment, but prominent chin development: can be corrected with chin surgery
We must take full advantage of a variety of methods that can correct the causes behind a long face.

-
+ Orthodontic planning in collaboration with oral and maxillofacial specialists
-
+ Osteotomy on elongated upper-gum bone
-
+ Osteotomy and relocation of the lower jaw to create a proper occlusion
-
+ Added chin surgery for better facial proportions, if needed
-
+ Firmly fixed into place with titanium pin
-
+ Continuous orthodontic treatment and recovery program

Facial Asymmetry Correction
Diagnosis of facial asymmetry is made when the face, vertically divided into half, has no left-to-right symmetry.
There is no perfect symmetry in a person’s face, but if the asymmetry is severe in degree, correction may be a good option.
Facial asymmetry does not stop at being an aesthetic issue. It can cause issues in the temporomandibular joint, and continued asymmetrical use of muscles and their development may create further asymmetry.
Cases of facial asymmetry can be categorized into (a) malocclusion in the two jaws creating crookedness in the mouth and the jaw, (b) asymmetrical development in facial structure, (c) asymmetry in the soft tissues, and (d) irregular curvature in the nose—one of the central features in the face—creating the asymmetry.
Among these cases, two jaw surgery is needed for malocclusion in the jaws.

Methods of Facial Asymmetry Correction by Patient Type
-
Malocclusion in the jaws and subsequently the teeth:
two jaw surgery needed -
Asymmetry in facial bone structure: can be corrected with cheekbone or square jaw surgery
-
Asymmetry in muscle or fat tissues: can be corrected with liposuction or masseteric reduction
-
Asymmetry caused by a curved nose: can be corrected with nose reshaping
Two jaw surgery for facial asymmetry includes teeth alignment.
Two jaw surgery for facial asymmetry—caused malocclusion in the jaws—includes teeth occlusion alignment as well. This is why BANOBAGI plans two jaw surgery with a professional teeth alignment in collaboration with oral and maxillofacial specialists. The surgery accomplishes teeth alignment with orthodontics, and the key is to osteotomize the crooked jawbones and fix them into position so that the upper and lower teeth create a proper horizontal occlusion.
Here, in addition to the properly aligned jaws, BANOBAGI adds treatments such as chin surgery or liposuction, creating a better-balanced facial structure.

-
+ Orthodontic planning in collaboration with oral and maxillofacial specialists
-
+ Location and degree of osteotomy determined to create a horizontal dental occlusion
-
+ Jaws moved exactly as planned and fixed with OSTEOTRANS
-
+ Chin surgery or soft tissue improvement added if needed
-
+ Continuous orthodontic treatment and recovery program

As the anesthetics wear off, patients may experience pain, but it will diminish over time.
The pain level during stitch removal or sterilization is that of a mild pinch.
Feverish sensations and pain caused by swelling can be addressed with the prescribed painkillers, and icing helps as well.
Without intermaxillary fixation, there will be no great discomfort.
Pain and swelling will be kept under control through a systemized and continuous aftercare.
