[ARTICLES] The “Witch’s Chin” That Becomes Prominent When Smiling—Restoring Natural Expression Through Mentalis Muscle Repositioning

The so-called “witch’s chin,” a condition in which the chin appears excessively elongated, pointed, or pulled downward when smiling, is not merely a cosmetic concern. In many cases, it originates from abnormal tension and misalignment of the mentalis (chin) muscle. While it may be unnoticeable at rest, facial expressions such as smiling or speaking can cause the chin to sink inward or be drawn downward, a result of overactivity of the mentalis muscle and imbalance with surrounding facial muscles. Recently, mentalis muscle repositioning surgery has gained attention as an effective solution for this condition. Rather than altering bone structure, this procedure repositions and re-fixates the overactive chin muscle to its proper anatomical location, structurally correcting the distortion that appears during facial expressions. Because it can address the witch’s chin deformity without bone resection, patient satisfaction has been notably high. Dr. Jang Yong-jun of ARC Plastic Surgery e...

"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.

Let's take a look at one of those cases.

[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.

As the surgery was performed completely by dissection of the skin from the bone, the shortening effect decreased and the chin tip looked wider than pre-op.

[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.
