What are the long-term complications of mandibular angle surgery?

Generally, mandibular angle surgery refers to mandibular contouring surgery. Mandibular contouring surgery involves making incisions inside the mouth or behind the ears to expose the mandibular angle bones, followed by bone cutting or grinding using specialized instruments to change the shape and size of the mandibular angle, thereby improving the facial contour.

The general reference price for mandibular contouring surgery is 20,000–80,000 yuan per session. Improvement is usually noticeable 1–3 months after surgery, but complications such as bleeding and hematoma may occur. Long-term complications of mandibular contouring surgery in old age may include facial laxity and sagging, reduced masseter function, nerve damage, bone hyperplasia, and discomfort in the surgical area. Detailed analysis is as follows:

1. Facial Laxity and Sagging

With aging, the skin naturally loses elasticity. Mandibular contouring surgery removes part of the bone, weakening the support for facial soft tissues. If proper postoperative care and maintenance are not performed, facial skin laxity and sagging may more easily occur in old age, manifesting as an unclear jawline or double chin.

2. Reduced Masseter Function

Mandibular contouring surgery may affect the masseter muscle to some extent. With aging, masseter function may further decline, potentially causing weak chewing and difficulty biting, which can affect normal eating and daily life.

3. Nerve Damage

If facial nerves are damaged during surgery, symptoms such as localized numbness may occur immediately. As aging progresses, nerve damage may not fully recover, potentially leading to persistent facial numbness, sensory abnormalities, and even impaired facial expression in old age.

4. Bone Hyperplasia

After mandibular contouring surgery, the physiological structure of the local bone changes. Under long-term physical activity and stress, bone hyperplasia may develop, potentially causing changes in facial appearance, pain, and affecting facial aesthetics and comfort.

5. Discomfort in the Surgical Area

After surgery, some individuals may experience discomfort in the mandibular angle area, including pain or stiffness, which may persist into old age.

It is recommended to visit a reputable hospital and undergo mandibular contouring surgery under a physician's guidance to ensure surgical effectiveness and safety. Postoperatively, maintain good oral hygiene, avoid forceful chewing and touching the surgical site, strictly follow medical advice to wear a headgear, maintain a light diet, and attend regular follow-up visits to ensure optimal recovery.
