"grade I: minimal hypoplasia of the mandible"
"grade II: functioning but deformed temporomandibular joint with anteriorly and medially displaced condyle"
"grade III: absence of the ramus and glenoid fossa"
"ear: hypoplasia, aplasia, or malformation of the external ear and middle ear; there may be a hypoplastic mastoid process with partial or complete lack of pneumatisation of the mastoid air cells"
"mandible: hypoplastic mandibular condyle, reduced height of the mandibular ramus with the chin deviated towards the affected side"
"maxilla: may be normal or reduced in height with delayed eruption of the mandibular and maxillary molars"
"zygoma: may be hypoplastic with short or absent zygomatic arch"
"orbit: may be reduced in dimensions and the frontal bone can be flattened"
"soft tissues: facial musculature, facial nerve supply, and other adjacent soft tissues may be hypoplastic"
"the temporomandibular joint deformity can range from mild hypoplasia of the condyle with normal joint anatomy to a grossly disorganised joint anatomy and pseudo-articulation of the condyle at the cranial base"
"The CT dataset may also be used to produce 3D models using advanced printing techniques popular for pre-surgical planning."
