Expert consensus on treatment of condylar hyperplasia and secondary dento-maxillofacial deformities

Condylar hyperplasia (CH), characterized by progressive facial deviation, occlusion disorders, and temporomandibular joint dysfunction, often requires combined temporomandibular joint (TMJ)-orthognathic interventions to reconstruct joint and occlusal functions as well as rebuilding harmonious facial expressions. Managing the dentomaxillofacial deformities secondary to CH involves hyperplastic condylar resection, orthognathic surgery, facial contour surgery and orthodontic treatment. Based on the activity of condylar hypertrophy, the severity of dentomaxillofacial deformity and malocclusion, an individualized treatment plan should be formulated to reconstruct joint functions, correct deformities and recover occlusal relationships. This expert consensus, informed by the latest clinical research and practical experience, addresses clinical considerations for surgical treatment strategies for patients with different CH types, delineating indications, objectives, procedures, and principles with the aim of providing clear and practical guidance for clinical practitioners.
