345 Square Jaw Reduction, Beyond Bone Resection: Balanced Changes from the Front and Side

Square jaw reduction must go beyond simple bone resection and comprehensively analyze the individual's anatomical structure, including the cortical bone, buccal fat, and masseter muscle. Through long-curve resection and a complex approach, 345 Plastic Surgery aims for natural contour improvement from both the front and side, adding trust with a safe surgical system.

345 Square Jaw Reduction, Beyond Bone Resection: Balanced Changes from the Front and Side

Hello, this is 345 Plastic Surgery, where we study the structural harmony of the face. When considering square jaw reduction, many people tend to focus on 'how much bone is shaved off.' However, to achieve highly satisfying facial contouring results, it is essential to first closely examine the anatomical characteristics, including not only the external shape of the jaw but also the muscles, fat, and the location of the nerve lines.

1. Four Anatomical Elements That Determine a Square Jaw

Simply trimming the jawbone does not make everyone's face slimmer. Through precise diagnosis, 345 Plastic Surgery comprehensively considers the following four elements.

  • Mandibular Angle: The outline of the jaw that angles below the ear, which determines the overall image of a square jaw.
  • Cortical bone: The hard outer layer of the jawbone. If the bone is thick, partially removing the cortical bone can be expected to reduce the width when viewed from the front.
  • Buccal fat: The fat inside the front cheek, commonly referred to as the deep cheek fat. Properly organizing excessive fat reduces the volume of the front cheek, making the impression much smoother.
  • Masseter muscle: The muscle responsible for mastication (chewing). If the muscle is overdeveloped, masseter muscle reduction is performed concurrently to further improve the jaw width.

2. The Evolution of Surgical Methods to Simultaneously Improve the Front and Side

In the past, square jaw reduction mainly focused on resecting the mandibular angle below the ear. While this method was effective in improving the profile line, it often had limitations in changing the width when viewed from the front.

To overcome these limitations, 345 Plastic Surgery appropriately combines cortical bone removal, buccal fat removal, and masseter muscle reduction. Through this, we soften the angular areas on the side while designing a three-dimensional contour that looks slim from the front as well.

3. Safe Long-Curve Resection That Protects the Nerve Line

The most critical aspect to be careful of during jaw surgery is the pathway of the inferior alveolar nerve. 345's long-curve resection is a method that safely avoids the nerve line while resecting in a smooth curve from the square jaw below the ear to the vicinity of the front chin. This method prevents the stepping phenomenon (secondary angle) and helps complete a natural jawline when viewed from the side.

4. Transparent and Honest 345 Safety System

As facial contouring is a highly difficult surgery, an environment where patients can undergo the procedure with peace of mind is crucial.

  • CCTV Monitoring: All surgical procedures are recorded to ensure transparency and eliminate concerns about ghost surgeries.
  • Dr. Call System: The day after surgery, the head doctor personally checks the patient's condition and monitors progress to aid in a swift recovery.
  • Customized Planning: By comprehensively analyzing bone thickness, skin elasticity, and fat volume, we propose a line optimized for the individual rather than a standardized surgery.

The goal of square jaw reduction pursued by 345 Plastic Surgery is not simply to shave off bone, but to complete the harmony of the entire face while preserving your natural individuality. Through precise diagnosis and a safe system, we will help you find your beautiful facial lines.
