Evaluation of Mandibular Ramus Morphology Using Computed Tomography in Patients With Mandibular Prognathism and Retrognathia: Relevance to the Sagittal Split Ramus Osteotomy

The mandibular ramus is thinner in patients with prognathism than in those with retrognathia. The distance of the point of fusion between the cortical plates above and posterior to the lingula is not influenced by the 2 types of mandibular deformity evaluated in this study. Computed tomography has proven to be a valuable tool to evaluate the morphology of the mandibular ramus.
