Abstract
Temporomandibular joint ankylosis (TMJA) secondary to congenital infiltrating lipomatosis of the face (CILF) is an exceptionally uncommon condition which is characterized by the involvement of unilateral facial soft tissues and bones. In some cases, the extensive exophytic bony growth in the temporomandibular joint region often extends toward the skull base and lies near adjacent vital structures. Only very few cases of TMJA associated with CILF have been reported in the literature. The authors report a case of a 36-year-old female with right TMJA secondary to CILF. The bony overgrowth in the right temporomandibular joint region was arising from a deformed right mandibular condyle, extending towards the ipsilateral temporal bone, greater wing of the sphenoid, skull base, and approaching the lateral limit of foramen ovale, and foramen spinosum. To prevent any damage to the skull base and adjacent vital structures and to achieve adequate mouth opening, the authors have performed a unique technique of subankylotic osteotomy for the release of TMJA, instead of conventional gap arthroplasty.
