MACS Uniqueness: Details Make the Difference

Point 1.Long-Curve Square Jaw Surgery
MACS performs long-curve square jaw surgery, leaving a slight natural angle under the ear for a result that looks naturally inherited. This completes a smooth jawline without the worry of secondary angles. Since it is performed through an intraoral incision, the burden of external scarring is minimized.

Point 2.1:1 Customized Square Jaw Stent
For accurate and precise resection, MACS produces patient-specific square jaw stents in-house immediately. Based on 3D AI facial analysis technology, the head surgeon directly designs and produces the stent to create various face lines, from natural lines to doll-like lines, as desired by the patient. Attaching it directly to the jaw during surgery allows for precise resection with almost no error or secondary angles.

Point 3.Securing Inferior Alveolar Nerve Location
During square jaw surgery and corticectomy, the most important part is accurately identifying the location of the inferior alveolar nerve, which is responsible for sensation in the lower jaw. At MACS, we use 3D AI facial analysis to precisely analyze the position of the nerve lines and the entire facial skeleton, establishing a safe surgical plan that drastically reduces the possibility of nerve damage.

Point 4.360-Degree Beautiful Face Line
To complete a slim and sharp jawline from any 360-degree angle, we perform not only square jaw surgery but also corticectomy, masseter muscle reduction, and, if necessary, buccal fat removal simultaneously. MACS pursues an All-round square jaw surgery that considers not only the bone but also the cheek fat, skin, and muscles.

MACS Square Jaw Surgery

Q.
What is the difference between Square Jaw Surgery and Corticectomy?

While square jaw surgery is for a slim jawline from the side profile, corticectomy is a surgery that reduces the width of the lower jaw when viewed from the front. At MACS, we perform both to improve the line into a sharp and slim one from any angle, whether front or side.

Q.
What are the benefits of using a Square Jaw Stent?

A square jaw stent refers to a patient-specific surgical guide. The advantage of using a stent is that it can be placed on the jaw during surgery to allow for accurate resection exactly according to the planned line. Since surgery without a stent carries the risk of resecting more than planned, leading to side effects like "dog-jaw" (over-resection) or secondary angles, our clinic uses stents for all procedures.

Q.
Is there a way to avoid the "Dog-Jaw" (over-resected) look?

If excessive resection is performed to make the face smaller, there is a high probability of creating a "dog-jaw" look where the face appears longer and older. Therefore, our clinic significantly reduces this possibility by leaving a slight natural angle under the ear and performing a smooth overall resection during square jaw surgery.
