Typical ranges for square jaw reduction; your surgeon confirms the details at consultation.
What is square jaw reduction?
Square jaw reduction (mandible angle reduction) is surgery that trims the prominent angle and outer layer of the jawbone to slim a wide lower face. At Marble Plastic Surgery in Gangnam, Seoul, it is planned with 3D-CT and performed by a board-certified plastic surgeon through incisions inside the mouth.
A square jaw can come from bone, an enlarged chewing muscle or both. Bone is reduced by a long curved cut that keeps a natural angle, and the outer cortex can be shaved to narrow the front view. Muscle bulk is treated separately if needed.
Who is square jaw reduction for?
Suitability is decided at a 1:1 consultation with your surgeon.
- A wide or angular jaw seen from the front or side
- A lower face that looks broad compared with the cheekbones
- Jaw asymmetry
- People for whom jaw botulinum toxin gave insufficient change
How square jaw reduction is performed at Marble
- Consultation and planning Your surgeon reviews X-ray and 3D-CT to measure the jaw angle, bone thickness and nerve course, and marks how much to remove on each side.
- Anesthesia and monitoring A board-certified anesthesiologist selects the anesthesia with your surgeon, administers it, and monitors you continuously throughout the procedure.
- Reducing the jaw angle Working inside the mouth, the surgeon removes the angle in a smooth curve, shaves the outer cortex where needed and checks symmetry.
- Recovery and discharge You rest in a private recovery room under monitoring. Before you leave, the team explains wound care, medication and your follow-up schedule.
Recovery and aftercare
Swelling is greatest in the first week and most of it settles within two to four weeks, with the final contour appearing over three to six months. A soft diet and a compression band are usually recommended early on.
- Regenerative laser care
- Ultrasound and radiofrequency care
- Before-and-after X-ray and CT imaging
- Recovery kit to take home

Frequently asked questions
Will square jaw surgery make my face sag?
When the reduction is proportionate, sagging is uncommon in younger patients. Those with loose skin may be advised to combine or follow with a lifting procedure.
Square jaw surgery or jaw botulinum toxin?
Botulinum toxin reduces muscle bulk temporarily. Surgery changes the bone permanently. The right option depends on whether bone or muscle causes the width.
When can I eat normally?
A soft diet is usually followed for about two to four weeks, progressing as comfort allows.
Who will perform my procedure at Marble Plastic Surgery?
The surgeon you consult with performs your surgery. Marble follows a surgeon-of-record policy with no substitute surgeons, and a board-certified anesthesiologist is on site full-time to manage anesthesia and monitoring.
