Clinical Features of Condylar hyperplasia
Condylar hyperplasia is more common in males, and it usually is discovered before the age of 20 years.
The condition is self-limiting and tends to arrest with termination of skeletal growth, although in a small number of cases continued growth and adult onset have been reported.
May progress slowly or rapidly. Patients have a mandibular asymmetry that varies in severity, depending on the degree of condylar enlargement.
The chin may be deviated to the unaffected side, or it may remain unchanged but with an increase in the vertical dimension of the ramus, mandibular body, or alveolar process of the affected side.
As a result of this growth pattern, patients may have a posterior open bite on the affected side.
Patients may also have symptoms related to TMJ dysfunction and may complain of limited or deviated mandibular opening or both caused by restricted mobility of the enlarged condyle.
