[ARTICLE] Square Jaw Surgery: Facial Bone Structure and Lower-Face Balance Matter More Than the Amount of Bone Reduction

A square jaw may be a concern when the lower part of the face appears wide from the front or when the angle of the jawbone below the ear is prominent from the side. This facial shape can be influenced by various factors, including not only the size and shape of the mandible, but also the development of the masseter muscles used for chewing and the amount of fat beneath the chin. Square jaw surgery is a type of facial contouring surgery that aims to improve the contour of the lower face by adjusting the shape and width of the mandible. However, the surgical outcome is not determined simply by removing a large amount of bone. It is important to determine the appropriate extent and location of bone reduction based on each individual’s skeletal structure and overall facial proportions. In particular, excessive reduction of the mandibular angle located below the ear may result in an unnatural side profile. On the other hand, reducing only the prominent area visible from the side may not ...

"Revision Genioplasty Case"


Surprisingly, a lot of people who have a concern about having a long chin come to me. And some as many people come for revision surgery as there are for the first surgery.

[1]  This is the case that the surgery was performed by reducing only "the chin tip" for the patient concerned about having a long chin.

[2]  In this case, as well, it literally was performed by reducing only the chin tip without considering the harmony of the connective jawline.

Both of them have thin skin, so the secondary angle was not only palpable but also visible on the outside.

In addition, as only one part was reduced, the skin and bone didn't get harmonized well as well as the skin of the area seemed sagging like a jowl.

[3]  This is the post-op CT of <Case_2> patient.

The patient wanted to remove the existing wires and remove the secondary angles as well as the angular feeling overall, so the revision surgery was processed by making the line smoother and connecting it to the angle under the ear.

Also, she had zygoma reduction surgery together.

You don't always have to do two or three types of facial contouring surgery at once, but it's desirable to plan surgery in consideration of getting connected with facial lines.

Plus, proceeding with the surgery considering the condition of the skin surrounding the bone at all times can produce satisfactory results without unnecessary further surgery.
