Early removal of mini-plate for correction of condyle position in patient of orthognathic surgery

Abstract

Orthognathic surgery has recently increased in patients with maxillofacial deformity. However, it has several post-operative complications, such as neurosensory changes of the lower lip, mandibular condylar displacement, and facial asymmetry. Studies show that the condylar position often changes after bilateral sagittal split ramus osteotomy (BSSRO), due to various factors, including inadequate mandibular movement during the operation, methods used for internal fixation, and masticatory muscle function. Condylar displacement can cause abnormal condylar movement, which can induce temporomandibular disorder or relapse due to condylar resorption. This study was conducted to evaluate changes in the condyle position after removal of the mini-plate at 2 or 4 weeks after orthognathic surgery.
