Aesthetic Double Jaw Surgery: Achieving Beauty and Functionality

Hello, I'm Dr. Park Jong-chul, a specialist in oral and maxillofacial surgery.

The term "aesthetic double jaw surgery" has recently gained attention, emphasizing the cosmetic purpose of the procedure. Unlike conventional double jaw surgery, which focuses on functional improvement, aesthetic double jaw surgery aims for aesthetic enhancement while maintaining normal occlusion. In other words, the key is to change the position and shape of the jaw to achieve facial balance and harmony while preserving the existing bite relationship.

Today, I'd like to introduce a case of aesthetic double jaw surgery where minimal anteroposterior changes to the jaw resulted in significant aesthetic improvement. The patient achieved a natural lip closure, improved lower lip protrusion, and elimination of chin wrinkles, leading to enhanced facial proportions and balance.

Is the main difference between aesthetic double jaw surgery and facial contouring surgery the presence of 'functional improvement'?

The answer is no.

While facial contouring surgery primarily focuses on aesthetic purposes, double jaw surgery can also address functional issues of the jaw. However, aesthetic double jaw surgery is performed on individuals without significant functional problems. Therefore, the most significant difference between the two surgeries lies in the 'post-operative appearance'.

Let's compare aesthetic double jaw surgery and facial contouring surgery using actual images.

Pre-operative Analysis

• The lower lip protrudes when viewed from the side, resembling a prognathic jaw.

• No skeletal asymmetry is observed. The anteroposterior position of the maxilla and mandible is within the average range.

• However, the lips do not close properly. The amount of maxillary incisor exposure is 5.62mm. The lower lip appears more prominent due to its thickness compared to the upper lip.

Initially, the patient desired overall facial reduction and anticipated satisfactory aesthetic results with facial contouring surgery alone. However, during the consultation, it was determined that aesthetic improvement would be limited without achieving natural lip closure, leading to the recommendation of double jaw surgery.

Straining the lower lip to close the mouth can make it appear thicker. This can create the illusion of a prognathic jaw even if the skeletal structure is normal. It can also cause chin wrinkles. These issues cannot be addressed with facial contouring surgery alone.

• The CT scan confirms that the patient underwent double jaw surgery along with genioplasty, mandibular angle reduction, and zygoma reduction.

• There is no change in occlusion before and after the surgery.

• The asymmetry of the zygoma is improved. The actual anteroposterior change in the chin position is only 0.78mm.

Clinical Photo Comparison: Before and After Double Jaw Surgery and Facial Contouring

• The lower lip is positioned more posteriorly than before, creating an aesthetic S-line between the lower lip and chin. The lips now close naturally without chin wrinkles.

• Compared to the pre-operative state, the maxillary incisors have moved upward, and the lips close properly. However, there is no significant difference in the anteroposterior position of the chin.

• Achieving comfortable lip closure alone can lead to significant aesthetic improvements. As demonstrated in this case, even minor changes in jaw position can result in substantial aesthetic enhancement..

Advantages of Aesthetic Double Jaw Surgery

• Reduced risk of nerve damage compared to facial contouring surgery alone: Moving the entire jawbone allows for secure positioning of the nerve canal.

• Natural jawline formation: By influencing changes in surrounding soft tissues, including submental fat, a natural jawline can be achieved.

  

  Advantages of Aesthetic Double Jaw Surgery

However, aesthetic double jaw surgery is a more extensive and complex procedure than facial contouring surgery. Therefore, it is crucial to undergo surgery with a qualified oral and maxillofacial surgeon. Thorough pre-operative diagnosis and sufficient consultation are essential to establish a personalized surgical plan.며, 수술 전 정밀한 진단과 충분한 상담을 통해 자신에게 맞는 수술 계획을 수립해야 합니다.
