Osteotomy surgery is a surgical treatment to change the face shape by removing part of the parotid bone. This surgery does not require the removal of all bones, but uses professional molds to thin the surface of the mandibular angle bone, thereby reducing the width. However, osteotomy surgery should not be imagined as an invincible simple ‘addition and subtraction’. The amount of mandibular bone that can be removed is very limited, up to a maximum of 5-6mm. So, where is it better to do osteotomy surgery?

Where is it better to do osteotomy surgery?

It is better to choose a reliable local hospital for osteotomy surgery, as generally reliable hospitals have relatively完善 management systems, reasonable charges, and are less likely to have a second charge. Moreover, the medical staff in general regular hospitals have relatively high professional ethics and are less likely to leak the privacy of aesthetes. Therefore, aesthetes will have some security in undergoing surgery in such hospitals. In addition, the doctors employed by regular hospitals have relatively high technical strength and are proficient in osteotomy surgery. The postoperative effects and the safety of aesthetes’ lives will be more secure. Generally, there are no side effects, and infections are unlikely to occur.

What is the harm of the osteotomy surgery?

1. Fracture, which is a common complication of surgical treatment. During the submandibular angle resection, it may be due to errors in the osteotomy line design or incomplete bone cutting, especially when there is bone cortex contact at the edge of the ascending ramus, using a bone knife to forcibly separate the mandibular angle, causing the osteotomy line to break off not from the edge of the ascending ramus but from the relatively defective sigmoid notch.

2. Unexpected bleeding during the operation and the formation of postoperative abscesses. Unintentional damage to blood vessels during the submandibular angle osteotomy can cause unexpected bleeding. If the intraoral mucosal incision is too high, it may cut the facial artery and vein, at which time ligation surgery or electrocoagulation hemostasis should be performed. If the osteotomy line is too high and injures the mandibular canal where the mandibular nerve and blood vessel bundle is located, it can cause severe bleeding.

3. The actual correction effect is not satisfactory. Some aesthetes not only have excessive growth and development of the mandibular angle and well-developed masseter muscles, causing the lower part of the face to be too wide, but also the superficial part is significantly spacious. It is impossible to achieve an idealized actual effect with a simple submandibular angle repair surgery.

4. The damage to the trigeminal nerve and parotid duct during the submandibular angle repair surgery through the intraoral approach is less likely to injure the trigeminal nerve. However, there is a possibility of damaging the buccal branch and mandibular margin branch of the trigeminal nerve if the masseter muscle is excessively superficially separated or the superficial masseter muscle is mistakenly removed during the operation. Separation of the masseter muscle and excessive height and superficiality may also damage the parotid duct.
