A radiographic study of the condylar hyperlasia

Condylar hyperplasia is a self-limiting condition characterized by a slowly progressing, enlargement of the mandible that results in facial asymmetry and a cross bite maloccusion. The facial asymmetry, open bite or cross bite, and radio graphic evidence of an enlarged condyle confirm the diagnosis of condylar hyperplasia. The etiology of the condition is unknown. This condition usually first becomes apparent during the second decade of life, when one condyle continues to grow while the other is no longer active. Radiographically, the condyle may appear enlarged or the neck of the condyle may be elongated or both may occur, sometimes, however, no raiographically demonstrable condylar abnormality will be noted. Surgical correction with subcondylar osteotomy is the treatment choice. We have observed two cases of condylar hyperplsia occurred in the left mandibular condyle of 24-year-old and 35-year- old women. We obtained that two cases were shown the followed results; 1. Clinically, both cases was unilaterally developed on C/C area, with temporomandibular disorders and pain, facial asymmetry and malcclusion. 2. Radiographically, hyperplastic mass confined to the condyle. 3. Histopathologically, these cases shown increased hypertrophic region in parts, and lamellated bone wit h irregular trabeculae.
