Condition Guide

About Mandibular angle hypertrophy

Understand the condition, common triggers and treatment options that may require specialist assessment.

Disease Introduction

Mandibular angle hypertrophy is mostly caused by overdevelopment of the mandible, manifesting as eversion of the mandibular angle, a wide lower face ("square face"), and sometimes accompanied by masseter muscle hypertrophy, affecting the aesthetics of the facial contour. Mandibular angle osteotomy and masseter muscle treatment can improve the lower facial contour, taking into account both function and aesthetics.


Cutting-edge high-precision diagnostic and treatment technologies

1. 3D-printed guide plate planning : Based on 3D image reconstruction, the osteotomy position and angle are designed, and a customized metal guide plate guides the osteotomy during the operation, improving accuracy and bilateral symmetry, controlling the error to the millimeter level, and avoiding accidental damage to the inferior alveolar nerve.
2. Computer-guided osteotomy : The surgical navigation is registered with preoperative digital information in real time, and dangerous structures such as the mandibular nerve canal are located in real time during the operation. The osteotomy is completed with precision and minimal invasiveness, reducing the risk of nerve damage and bleeding.
3. Long Curve Osteotomy : An ultra-long curve osteotomy is performed from the ear root to the chin to create a smooth and natural jawline. The width of the lower face is significantly narrowed from the front, improving the appearance of a square face. The contour transition is natural, the postoperative effect is long-lasting, and the jaw angle is not abrupt. The profile lines are smooth.
4. Precise grinding of the entire area : Unlike conventional splitting of the outer plate, the entire outer plate of the mandible is finely ground to ensure a smooth transition between the side and frontal contours, avoid step-like appearance and unnaturalness after surgery, improve overall smoothness and facial harmony, and take into account both the precision of osteotomy and the natural transition of soft tissue. The follow-up plan is individually formulated by a multidisciplinary team.
5. Treatment of masseter hypertrophy : For patients with masseter hypertrophy, a combination of botulinum toxin injection or partial masseter muscle resection is used to narrow the width of the lower face from both bone and muscle levels, synergistically improving the lower face contour and facial proportions. The effect is harmonious and natural. With standardized follow-up evaluation after surgery, both long-lasting shaping and safety and comfort are taken into account.
