[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...

*Detailed Design = Basics of Facial Contouring Surgery*


One of the biggest concerns for those planning cheekbones surgery is "cheek skin sagging".



As shown in Figure 1, there are ligaments around the cheekbones that protect against sagging.

Looking at Figure 2, you can see that the osteotomy line in green is located in the area where these ligaments are located.


Therefore, the extent of detachment, location of the osteotomy, and bone fixation should be determined in consideration of the current patient's bone structure and skin condition.

It is not always for the patient by just simply fixate on it high.

Surgery should be differentiated to suit individual needs, as can be seen in the CT of patients who performed surgery in ARC.

Of course, accurate bone fixation is fundamental.
