Condylar hyperplasia: cephalometric study, treatment planning, and surgical correction (our experience)

We have studied and treated 12 selected cases of condylar hyperplasia. All of our cases showed no clinical or instrumental sign of still active hyperplastic growth of the mandibular condyle. The cephalometric studies demonstrated in all cases a pathologic vertical growth of the maxilla interesting the posterior segments on the same side of the hyperplastic condyle. We decided not to perform a condylectomy because we did not expect the condyle to grow any further. The treatment consisted of Le Fort I osteotomies and sagittal split osteotomies sometimes in combination with genioplasty and mandibular remodeling. The mandibular physiologic movements were preserved in all cases.
