Abstract: Facial asymmetry associated with condylar hyperplasia (CH) has been become the object of study in recent years. The aim of
this study is to demonstrate the importance of analyzing the presence of CH in cases of facial asymmetry. Twenty-seven consecutive
patients were studied without distinction of age or gender; all the patients consulted for treatment of facial and/or mandibular
asymmetry and voluntarily agreed to participate in the study. All the patients underwent facial cone beam tomography and bilateral TMJ
as well as a detailed history where they indicated the progression of the disease; in cases of active evolution determined by clinical
analysis and imaging, a SPECT analysis was performed to define the isotope uptake. 29.6% of the subjects with scintigram exhibited
active CH with a more than 10% difference in uptake between the two condyles; 18.5% presented differences in uptake between 5%
and 10%. Active CH was related to the age and gender of the subjects, being more prevalent in women than in men. The aggression
level of the uptake was also related to the subject’s age. 55% of the subjects presented with some type of orthodontic treatment with no
diagnosis of TMJ pathology in the initial consultation. It can be concluded that CH is associated with facial asymmetries and must be
studied integrally before assessing treatment options. (IJCEM1309002).
