Abstract
Post traumatic condylar hyperplasia condition is an increase in the total number of cells due to increased activity, which exist only as long as the activity or the stimulus is applied. When it is removed, the tissue returns to the normal state; however, a secondary structural alteration in the general architecture due to accompanying degeneration may render a complete return to the normal state impossible. Mandibular asymmetry following condylar injury is poorly documented as a cause of facial asymmetry. leFort1 (low-level fracture) osteotomies and bilateral sagittal mandibular osteotomies, which are comprehensive surgical plans, correct the facial deformity together with the occlusion. An innovation of new clinical concepts has been used in the correction of facial deformity in 11 patients with post-traumatic condylar hyperplasia condition (syndrome) by applying a new modified allo plastic material (subperiosteal acrylic implant).
