Things to Consider Before Men's Square Jaw Surgery: Criteria for Flawless Facial Contouring Design
Men's facial contouring begins with understanding a skeletal structure different from women's. 345 Plastic Surgery provides a detailed guide on the core design points of men's square jaw surgery, which improves the heaviness of the lower face while maintaining masculine charm through a three-dimensional analysis of bone thickness, muscle development, and fat distribution.

Men's Square Jaw Surgery: Why 'Design' Matters More Than Simple Resection
The male skeleton is characterized by thicker bones and more distinct angles compared to females. Therefore, rather than simply focusing on shaving down a large amount of bone, the post-operative impression can vary greatly depending on how the scope and direction of the resection are set. At our clinic, we aim for a customized design that precisely refines only the excessively prominent areas while maintaining a masculine structure.

Anatomical Characteristics of the Male Skeleton and Surgical Approach
The main characteristics of the male skeleton that must be considered during men's facial contouring surgery are as follows:
- Bone Size and Thickness: The bones themselves are larger and thicker than those of women, requiring precise surgical techniques during resection.
- Development of the Jawline and Cheekbones: Rather than unconditionally removing the angle of the jawline, which gives a strong impression, it is important to refine it smoothly.
- Maintaining an Attractive Line: An incorrect design can make the face look flat or diminish masculine charm, so careful attention is required.

Men vs. Women: The Crucial Differences in Facial Contouring Design
Since the aesthetic standards pursued differ by gender, the surgical direction must also be differentiated.
| Category | Men's Square Jaw Surgery | Women's Square Jaw Surgery |
|---|---|---|
| Goal | Refining excessively prominent areas | Smooth connection of the overall line |
| Line Treatment | Leaving a gentle angle to maintain masculinity | Emphasizing smooth curves and slimness |
| Key Point | Improving the stable proportion of the lower face | A slim impression that maintains three-dimensionality |

3 Combined Solutions for Comprehensive Improvement
Highly satisfying results can be expected only when muscle and fat are considered together, not just the bone structure.
1. Cortical Osteotomy
This is a method of reducing the actual thickness of the bone by thinly peeling off the cortical bone, the outermost layer of the jawbone. It helps enhance the frontal slimming effect.
2. Masseter Muscle Reduction
If the masseter muscle, which is used for chewing food, is overly developed, it is appropriately reduced to decrease the volume of the lower face.
3. Buccal Fat Removal
By removing the deep fat layer inside the front cheek, also known as buccal fat, it helps the jawline become more clearly defined.

We Recommend Men's Square Jaw Surgery for the Following Individuals:
- Those whose jaw angle is overly developed, giving a very harsh impression
- Those whose lower face looks wide and heavy from the front
- Those with an irregular face shape due to an imbalance between the cheekbones and jaw
- Those whose face appears larger than it actually is due to masseter muscle and fat development

345's Promise for Safe Surgery
As facial contouring is a highly difficult surgery that deals with areas where nerve lines pass, verifying the safety system is essential. Our clinic has three resident anesthesiologists and a university hospital-level monitoring system, and provides a trustworthy medical environment where the entire surgical process can be observed via CCTV.
