Comparison after mandibular angle surgery

The comparison after mandibular angle surgery mainly involves dimensions such as facial contour improvement, occlusal function recovery, and soft tissue adaptability. The surgical effect varies from person to person and needs to be comprehensively evaluated based on factors such as preoperative design, bone resection volume, and postoperative care. The facial contour changes are most significant in the early postoperative period, with the curvature of the mandibular angle becoming softer and the smoothness of the lateral lines improving. The peak period of swelling occurs 3-5 days after surgery, and visual errors may occur when comparing preoperative photos. Bone healing takes 3-6 months, during which there may be temporary atrophy of the masseter muscle leading to soft tissue relaxation. Some beauty seekers may experience slight bilateral asymmetry, which is related to the accuracy of intraoperative osteotomy and the uniformity of postoperative pressure dressing. Six months after surgery, taking a CT scan of the head can accurately evaluate the extent of bone remodeling, and at this point, the compatibility between soft tissue and bone is basically stable.

Long term comparison should pay attention to changes in occlusal function, and in a few cases, temporomandibular joint clicking or decreased chewing efficiency may occur. Cases using three-dimensional osteotomy technology are easier to maintain the height of the mandibular ramus and reduce the risk of secondary mandibular retrognathia compared to traditional linear osteotomy. A VAS score survey conducted 12 months after surgery showed that about 80% of the patients were more satisfied with the improvement of the side profile than expected. Attention should be paid to excessive osteotomy, which may result in missing contours in the mandibular angle area and disrupt facial mechanical balance.

It is recommended to wear an elastic headgear for 3 months after surgery to promote soft tissue adhesion and avoid hematoma caused by early intense exercise. Regular follow-up of maxillofacial 3D CT monitoring of bone healing progress. If there is abnormal pain or limited mouth opening, timely follow-up is necessary. Postoperative diet should gradually transition from liquid to soft foods, combined with oral muscle function training to help adapt to the new bite relationship.
