Introduction: Introduction: Condylar surface of mandible has varied curved shapes and its assessment is important clinically for better management of Temporomandibular (TMJ) pathologies. Multidetector Computed Tomography (MDCT) is the modality of choice for curvature analysis of mandibular condyle.
Aim: To assess the curvature types of mandibular condyle by MDCT. Symmetry of condylar curvature was also analysed in the present study.
Materials and Methods: This retrospective descriptive analysis of bilateral TMJ was done in 500 adult cases. Curvature analysis of bilateral mandibular condyles was done by MDCT in coronal reformatted images. Statistical Analysis: Statistical Analysis was done using SPSS version 20 for frequency of each curvature type and their symmetry.
Results: Type D was most common (bilateral TMJ considered) with 335 cases (33.50%) among the total number (n=1000) of TMJ studies. On right TMJ studies (n=500) Type D was most common with 172 cases (34.40%) and on left TMJ studies (n=500) type D was again most common with 163 cases (32.60%). Of the total 257 cases that showed symmetry, Type D was most common with 90 cases (35%) and also to be the most common type seen in males with 50 cases (30.8 %) and females with 40 cases (42%).
Conclusion: Curvature analysis is done to know the morphological types of mandibular condyles. Type D is most common type of curvature seen and is symmetrical. Condylar curvature is an important determinant factor for various TMJ pathologies with MDCT offering an excellent non invasive imaging modality for curvature analysis.
