Condylar hyperplasia is a self-limiting condition characterized by a slowly progressing,
enlargement of the mandible that results in facial asymmetry and a crossbite
malocclusion. The facial asymmetry, open bite or crossbite, and radiographic 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the other is no longer active.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 appeal enlarged or the
neck of the condyle may be elongated or both may occur, Sometimes, however, no
radiographically demonstrable condylar abnormality will be noted. Surgical correction
with subcondylar osteotomy is the treatment of choice.
We haute observed two cases of condylar hyperplasia 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 malocclusion.
2. Radiographically, hyperplastic mass confined to the condyle.
3. Histopathologically, these cases shown increased hypertrophic region in parts, and
lamellated bone with irregular trabeculae.
