case_images: The surface mucosa was normal [Figure 1].
case_images: Panoramic radiography reveals a concavity of the right posterior border of the ramus, a deep coronoid notch, and prominent antimonial notching

case_images: Routine panoramic radiography for dental prosthetic treatment revealed a concavity of the right posterior border of the ramus, a deep coronoid notch, and prominent antegonial notching [Figure 2].
case_images: (a) Axial bone computed tomography imaging demonstrates that the right condylar head is small and deformed (arrow). (b) The right coronoid process (arrow head) and lateral pterygoid processes (arrow) are hypoplastic. (c) There is a corticated, irregularly shaped depression of the lateral aspect of the right ramus. (d) The right mandibular canal appears widened (arrow). (e) The ascending ramus is bowed

case_images: CT revealed that the right condylar head was small and deformed [Figure 3a]. The right coronoid process and lateral pterygoid processes were hypoplastic [Figure 3b]. There was a corticated, irregularly shaped depression of the lateral aspect of the right ramus [Figure 3c]. The right mandibular canal appeared widened [Figure 3d]. The ascending ramus was bowed [Figure 3e].
case_images: (a) Axial computed tomography imaging demonstrates that the right temporal muscle (arrow head) and lateral pterygoid muscles (arrow) are hypoplastic. (b and c) There are enhanced lesions within the right masticatory muscle space (arrows). (d) There are no contrast-enhanced masses, instead hypodense but fat-like tissue adjacent to the bone deformity of the mandible (arrow)

case_images: The right temporal muscle and lateral pterygoid muscles were hypoplastic [Figure 4a and b]. There were enhanced lesions within the right masticatory muscle space [Figure 4b and c], and there were no contrast-enhanced masses, instead hypodense but fat-like tissue adjacent to the bone deformity of the mandible [Figure 4d].
case_images: Three-dimensional computed tomography imaging demonstrates mandibular asymmetry is evident, and reinforced the changes of the right mandible. There are concavity of the right posterior border of the ramus, elongated condylar necks, prominent antegonial notching, and hypoplastic appearance of the condyle and coronoid process

case_images: Mandibular asymmetry was evident and reinforced the changes of the right mandible previously noted on the panoramic radiography and bone window CT, including concavity of the right posterior border of the ramus, elongated condylar necks, prominent antegonial notching, and hypoplastic appearance of the condyle and coronoid process [Figure 5].
