Abstract
|
|
|
Mandibular condylar hyperplasia is an uncommon condition of excessive unilateral growth of the condyle causing facial asymmetry
and occlusal alterations. The etiology of condylar hyperplasia is unclear, but several factors are suspected, including previous
trauma, hormonal disturbances, and abnormal functional loadings. Acute or chronic recurrent dislocation of temporomandibular
joint (TMJ) is common, but long-standing dislocation is rare. We present two cases of the exophytic condylar hyperplasia
that lasted for over 20 years with TMJ dislocation. In both cases, we performed a condyloplasty to restore normal occlusion
and facial symmetry, with satisfactory results
