Aim: Condylar hyperplasia (CH) is an alteration of condylar development, which causes mandibular asymmetry and dentofacial deformity in different magnitudes. The aim of this investigation was to determine the relationship of the condylar size and mandibular asymmetry in patients with type 1B CH through analysis of cone beam computer tomographies (CBCT). Materials and Methods: The research was a quasi-experimental study. Thirty subjects were studied using a CBCT. Patients were recruited from the Dental Service of the Oral and Maxillofacial Surgery Unit of the Hospital Guillermo Almenara Irigoyen, Lima, Peru, between 2016 and 2018. Anteroposterior, upper–lower, and middle–lateral distance measurements of the condyle head were obtained and correlated with the difference of the measurements obtained. Spearman correlation coefficient was used and established a level of significance of P < 0.05. Results: The results showed a correlation between condylar size and mandibular asymmetry. In addition, it was found that the greater the difference in the upper–lower part of the hyperplastic (CH) and nonhyperplastic (NCH) condyles, the greater the magnitude of the mandibular asymmetry, finding a positive correlation r = 0.331 with significant value (P = 0.037). Conclusion: There was a positive correlation between upper–lower difference and mandibular asymmetry. Similarly, in the middle–lateral measurement, a negative correlation was found between the condylar difference and the mandibular symmetry in the anteroposterior measurement.
