How to correct masseter muscle hypertrophy

Generally, masseter muscle hypertrophy may be caused by genetic factors, poor chewing habits, preference for hard foods, endocrine disorders, periodontitis, and other reasons. Treatment options include general management, medication, osteotomy, bone grinding surgery, and injection of botulinum toxin type A, all of which should be conducted under the guidance of a physician. Specific analyses are as follows:

1. Genetic Factors

Part of the cause of masseter muscle hypertrophy may be hereditary. Some families may carry genes associated with more developed masseter muscles, making descendants more prone to this condition under similar circumstances. In daily life, symptoms can be alleviated through facial muscle massage and stretching exercises. Alternatively, under the guidance of a specialist, osteotomy surgery may be performed. This surgical procedure involves making incisions on both sides of the oral cavity and partially removing or grinding down the mandible to alter facial contours and reduce the visual prominence of the masseter muscle. The reference cost is typically 50,000–100,000 yuan per session, with improvements usually visible within 1–2 months. However, possible complications include infection, bleeding, and hematoma.

2. Poor Chewing Habits

Long-term不良 chewing habits, such as frequently chewing gum or betel nuts, can lead to overuse of the masseter muscle, resulting in hypertrophy. Improving chewing habits in daily life—such as avoiding excessive gum chewing—is recommended. Patients may consider bone grinding surgery under the guidance of a qualified physician. This procedure involves making incisions inside the mouth and using a high-speed burr to grind down the mandible, thereby reducing facial width. The reference cost ranges from 50,000 to 60,000 yuan per session, with results generally noticeable after 1–2 months. Potential risks include infection, bleeding, and hematoma.

3. Preference for Hard Foods

Long-term consumption of excessively hard foods increases strain on the masseter muscle, leading to overdevelopment and hypertrophy. This condition results in prominent masseter muscles and may cause difficulty or fatigue during chewing. Adjusting dietary habits by avoiding prolonged intake of hard foods is advised. Under professional medical supervision, injection of botulinum toxin type A may be used. This treatment involves injecting botulinum toxin type A directly into the masseter muscle to induce muscle relaxation, thereby reducing muscle volume. The reference price is approximately 2,000–6,000 yuan per injection, with improvement typically seen within 7–15 days. Possible side effects include mild pain, swelling, or bruising at the injection site.

4. Endocrine Disorders

Endocrine imbalances may result from stress, emotional fluctuations, chronic sleep deprivation, and other factors. Such imbalances can lead to abnormal hormone levels—for example, excessive secretion of growth hormone or thyroid hormone—promoting masseter muscle hyperplasia. Symptoms may include menstrual irregularities, insomnia, and palpitations. Patients should follow medical advice and use medications such as progesterone capsules, Wuji Baifeng Pills, or furosemide tablets as prescribed.

5. Periodontitis

Periodontitis is an inflammatory reaction affecting the tissues surrounding the teeth. It can keep the masseter muscle in a prolonged state of tension, contributing to muscle hypertrophy. Associated symptoms may include bad breath and loose teeth. Treatment should follow medical guidance and may include medications such as metronidazole tablets, diclofenac sodium sustained-release tablets, and compound chlorhexidine mouthwash.

It is recommended to seek care at a reputable medical facility and undergo procedures under the supervision of qualified professionals to ensure both effectiveness and safety. To maintain harmonious facial contours, individuals should adopt a balanced diet, avoid long-term consumption of hard foods, maintain healthy chewing habits, and minimize overuse of the masseter muscle to help prevent its hypertrophy.
