Coronoid process hyperplasia with limitation of mouth opening is rare. The pathology is often ignored, but it can be easily detected using dental panoramic view of x-ray films. Definition of the coronoid process hyperplasia can be made by measuring the height of coronoid process and the ratio of coronoid/condyle height on lateral cephalometric x-ray film. Etiology of the coronoid process hyperplasia can be congenital or acquired. Differentiation of the diagnosis may be difficult. The congenital type occurs at early age with clinical manifestations. Proposed hypotheses for the formation of coronoid process hyperplasia include increased activity within the temporalis muscle from conditions such as functional stress, compression, and tension. For patients with coronoid process hyperplasia and restriction on mouth opening, conservative treatment should first be attempted. Surgical treatment is considered if conservative treatment fails. Coronoidectomy with early mobilization and aggressive physiotherapy corrects the problem. We present a patient with coronoid process hyperplasia with limitation of mouth opening who was successfully treated.
