Facial Trauma and Fracture Management

Dysfunction of the temporomandibular joint (TMJ) can be caused by several factors, including malocclusion, with surgical treatment indicated in specific cases. The orthognathic surgery must be planned correctly, since technical variations, stability in fixation, and incorrect positioning of the condyle may be a pre-disposing factor for bone resorption. Condylar resorption in the TMJ is a pathology that affects female patients with malocclusion, such as Class II skeletal malocclusion, with or without open bite, with previous TMJ disorders that were treated with bimaxillary osteotomy involving great mandibular advancements. This paper aims to report the clinical case of a patient with Class II skeletal malocclusion, who underwent bimaxillary orthognathic surgery with maxillary intrusion and mandibular advancement followed by counterclockwise rotation, and who exhibited post-surgical condylar resorption.
