- Abstract
Fibrodysplasia ossificans progressiva (FOP) is a rare condition characterized by progressive heterotopic ossifications and congenital hallux valgus deformities. The common underlying genetic cause is an ACVR1 mutation, resulting in altered bone morphogenetic protein (BMP) regulation. Trauma and/or minor procedures aggravate the abnormal bony formation in soft tissues. This report presents a 3-year-old child with this condition who presented pseudo-ankylosis of the temporomandibular joint (TMJ) after minor craniofacial trauma. Abnormal ossification in the medial pterygoid muscle was identified as the causative abnormality for the presentation with trismus.
