The study was designed to evaluate facial asymmetry in skeletal class I, skeletal class II and skeletal class III, subjects using posteroanterior cephalometric analysis. The total sample included in the study was 60 subjects which are sub-divided into three groups of 20 each. The conclusion of the study was: a. Maxillary width was found to be significantly greater in skeletal class II than skeletal class I subjects. b. Mandibular width, lower facial height and mandibular comparison was found to be significantly greater in skeletal class III than skeletal class I subjects. c. Over all left side dominance was present which was not statistically significant.
