The Pierre Robin sequence (PRS) and the Treacher Collins syndrome (TCS) are conditions that cause significant abnormalities of jaw. This study was conducted in anticipation of evaluating the morphology of interforaminal region and identify the anatomic variations: anterior loop and mandibular incisive canal, in individuals with PRS and TCS by cone-beam computed tomography and compare them with individuals without craniofacial anomalies. By applying the t-test, the results showed no statistically significant difference, allowing to infer that there are no significant differences in interforaminal mandible morphology between groups and indicated that the prevalence and location of the studied anatomic variations are consistent with those described in literature.
