Abstract:

Objective: Unilateral Condylar hyperplasia of mandible is overdevelopment of condyle, unilaterally leading to facial asymmetry, mandibular deviation, malocclusion and TMJ dysfunction. The condition represents a challenge to both orthodontists and oral and maxillofacial surgeons because of the occasional progressive behavior of the anomaly and the subsequent severe dentofacial deformity. The aim of the current study is to evaluate different treatment modalities of unilateral condylar hyperplasia in relation to the condylar activity and facial asymmetry. Methods: This a case-series study evaluated 16 patients with condylar hyperplasia that met the inclusion criteria between 2015 and 2023. Preoperative radiographic evaluation with panoramic, lateral cephalometric and posteroanterior cephalometric imaging for diagnosis, evaluation of the degree of facial asymmetry and treatment planning were performed for all the patients enrolled in the study. Results: Five patients (31%) underwent condylectomy with orthodontic treatment, 2 (12.5%) underwent genioplasty with orthodontic treatment, and 3 (19%) underwent condylectomy with adjunctive jaw surgery with orthodontic treatment. While 6 (37.5%) patients selected to be treated by the orthodontic treatment regardless the minimal degree of facial asymmetry. Conclusion: Simultaneous condylectomy and orthognathic surgery provides predictable and stable outcomes for patients with active unilateral condylar hyperplasia and associated dentofacial deformities. Virtual surgical planning allows the precise definition of the level of condylectomy, and custom-made 3D printed cutting guides are useful to reproduce virtual measurements during surgery.
