Square Jaw Surgeryjawline reduction surgery
Considering the bone, muscle, and even the thickness of the fat, we create a naturally slim facial shape.
What is square jaw surgery at NANA Plastic Surgery?
Square jaw surgery resects only as much of the angular jawbone as necessary and corrects lower-face asymmetry to complete a natural, slim face line.
Rather than simply removing the angular part, it sets the optimal angle and proportion of the mandibular line extending to the chin, and carefully analyzes each individual's nerve position and soft-tissue structure to improve the key areas that define the facial shape — from the jawbone below the ear to the front of the chin — without worrying about a secondary angle.
Self-diagnosis for a square jaw
From the front, the lower face looks wide and the chin looks short. From the front, the facial shape itself looks wide and spread out, with a U-shaped lower end.
From the front or side, the facial line from the chin backward is almost horizontal. In profile, the lower jaw is angled at almost 90 degrees. When chewing, the muscles thicken, making the lower face look even wider.
Self-diagnosis for
a square jaw
If you are concerned that the lower part of your face
looks wide or your jawline looks blunt and heavy
every time you take a photo,
it is worth checking your square jaw type.
In particular, if any of the items below apply to you,
it may be a case where a prominent mandibular angle
or developed jaw muscles appear together.
01
From the front, the lower face looks wide and the chin looks short.
02
From the front, the facial shape itself looks wide and spread out, and the chin area is U-shaped.
03
From the front or side, the facial line from the chin backward is almost horizontal.
04
In profile, the lower jaw is angled at almost 90 degrees.
05
When chewing, the muscles thicken, making the lower face look even wider.
06
The lower face looks wide and heavy, giving a harsh impression.
What makes square jaw surgery special at NANA Plastic Surgery
Square jaw surgery combines cortical osteotomy, buccal fat removal, masseter reduction, and more as needed to create a perfect V-line.
Long-curve resection
Resection in a long curve from the mandibular angle below the ear to the chin improves an angular jawline into a soft, natural one.
Cortical removal
The developed outer cortical bone is also improved, reducing the width of the face and the thickness of the lower face as seen from the front.
Masseter reduction
The masseter muscle, which is responsible for chewing, is also considered and partially resected to slim a lower-face line that looks wide due to muscle.
Buccal fat removal
Improving the buccal fat located in the deep layer of the lower face softens a heavy, blunt-looking impression and creates a more refined facial line.

Advantages of square jaw surgery at NANA Plastic Surgery
We closely analyze every element that makes up the face and perform surgery with the most appropriate method.
No secondary angle
Rather than cutting only the angular part of the jawbone, a special surgical saw is used to remove bone in a long, smooth line all the way to the front of the jaw.
Effective from both the front and side
The jawline becomes slimmer not only from the front but also from the side, creating a three-dimensional facial shape.
Maximum volume reduction effect
Simply resecting a large amount of bone does not bring good results. Effective volume reduction is what matters.

NANA's guide to
precautions after facial contouring surgery
01
Washing & showering
Until the stitches are removed, please wipe areas other than the surgical site with a damp towel.Until the tape or stitches on your face are removed, please wipe areas other than the surgical site with a damp towel.
You may brush your teeth from the day after surgery.From the day after surgery, brush your teeth as usual but carefully with a small toothbrush. After intraoral incision surgery, gargle with the prescribed Hexamedine diluted at a ratio of 7 parts water to 3 parts Hexamedine. We recommend gargling after every meal, and rinsing your mouth gently at intervals of about 3–4 hours.
02
Recovery
Irritation or a strong impact to the surgical site may cause bleeding or hematoma.Irritating the surgical site or receiving a strong impact may cause bleeding or hematoma. Please avoid actions that put pressure on the face (straining during vomiting or bowel movements, coughing, sneezing, bending your head down, etc.).
There may be reduced sensation in the cheeks, lips, or teeth.There may be reduced sensation in the cheeks, lips, or teeth. However, this gradually improves over 1–2 months at the shortest and up to a year at the longest, so there is no need to worry.
03
Swelling care
After surgery, swelling or bruising may move downward and descend as far as below the neck.Swelling or residual tissue may look asymmetrical, but it returns to symmetry once the swelling has fully subsided, so there is no need to worry.
Apply warm/cold compresses at the appropriate times after surgery.Cold compresses are recommended for the first 3 days after surgery while the face is swollen. They help prevent bleeding and reduce swelling. From day 4 after surgery, warm compresses are recommended for effective management of swelling and bruising. Because sensation in the face is dulled, please be careful of frostbite or burns from compress packs.
04
Diet
Day after surgery – 1 week after surgeryFor one week from the day after surgery, eat thin porridge-type foods and do not use a straw.
1–4 weeks after surgery (6 weeks for cheekbone surgery)From 1 to 4 weeks after surgery, you may eat regular meals but only soft foods. Avoid hard and chewy foods. ※ Foods to avoid: meat (except finely minced meat), cubed radish kimchi, seasoned vegetables (cut kimchi and vegetables into small pieces), squid, dried fish, rice cakes, gum, candy, nuts, etc.
05
How to wear the facial band
Please wear it for 3 days after surgery.Wear it for 3 days after surgery; you do not need to fasten the band too tightly or wear it 24 hours a day.
From day 4 to 1 week after surgery, do not wear it and leave the area open.
From 1 week to 1 month after surgery, wear the band intermittently.Wearing the band intermittently from 1 to 4 weeks after surgery helps the skin contract (especially after chin surgery), but it is not essential.
06
Additional notes for cheekbone surgery
If you had cheekbone surgery, please be sure to follow the precautions below.Please refrain from blowing your nose and opening your mouth wide (more than three fingers' width) for 6 weeks. However, keep opening your mouth to a natural degree to prevent adhesion of the jaw joint. Also, if the dressing at the sideburn incision gets wet, simply replace it with another bandage.
