[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.

[ARTICLE] Dr. Soonbeom Kwon of ARC Plastic Surgery Gives Lecture on Zygoma Reduction at ‘APS KOREA 2025’

Dr. Soonbeom Kwon, Chief Director of ARC Plastic Surgery Clinic, presented his research on zygoma reduction techniques at APS KOREA 2025 (Aesthetic Plastic Surgery Korea 2025), an international aesthetic plastic surgery conference held on April 19 at Seoul Dragon City. APS KOREA is Korea’s leading academic conference in aesthetic plastic surgery, held annually since 1985. It brings together plastic surgeons from Korea and abroad to share the latest insights and research findings. At this year’s event, Dr. Kwon delivered a lecture titled “Zygoma Surgery Methods Based on Facial Conditions,” drawing from his extensive experience in facial contouring. He introduced the high-L and low-L osteotomy techniques tailored to various patient cases and shared clinical outcomes of each. In his presentation, Dr. Kwon emphasized that zygoma reduction is not merely a procedure to reduce bone size, but one that requires a precise, proportional approach considering the overall balance of the face. As the zygomatic bone plays a central role in determining facial contour, excessive resection can result in an elongated or artificial appearance, making personalized surgical design essential. Dr. Kwon also highlighted the importance of thoroughly analyzing the patient’s facial bone structure, soft tissues, and zygoma morphology to refine surgical techniques. He stressed the need for surgical planning that balances both aesthetic outcomes and functional safety. Dr. Kwon continues to contribute to the advancement of plastic surgery techniques through active academic participation and research, fostering collaboration with professionals both in Korea and around the world. – Medical Today, Reporter Seongwoo Cho (ostin0284@mdtoday.co.kr)
