Clinical presentation and management of osteochondroma of the coronoid process (Jacob’s disease)

Abstract

ABSTRACT Jacob’s disease is characterized by osteochondroma arising from the coronoid process of the mandible. Patients usually present with limitations of mouth opening and cheek prominence. Computed tomography of facial bones with three-dimensional reconstruction was considered the gold standard for diagnosis. Management was principally surgical which involved the removal of the coronoid process either by intraoral or extraoral approach. Postsurgical mouth-opening exercises are considered important for maintaining the obtained results.
