Temporomandibular Joint Ankylosis In True Hemifacial Hyperplasia With Infiltrative Lipomatosis - A Case Report

Congenital infiltrative lipomatosis of the face is a benign condition in which mature adipocytes invade adjacent tissues causing diffuse fatty infiltration into the surrounding soft tissue and hyperplasia of the adjacent bone on the affected side. This case report of a 37-year-old female with congenital facial asymmetry and diffuse swelling on the right side of the face suggests true hemifacial hyperplasia, which is supported by both clinical and radiographic data which showed severe involvement of underlying bony structures of the temporomandibular joint, sphenoid, temporal, zygoma, right maxilla, mandible, associated dentition and adjacent soft tissues. It also revealed lipomatous enlargement with right temporomandibular joint ankylosis reported with multiple etiological factors and marked trismus, for which functional rehabilitation was achieved following surgical intervention
