Eagle syndrome

The eagle syndrome is a condition characterized by a calcification of the stylohyoid ligament. When it occurs, it is usually after a tonsillectomy. Periostitis and osteomyelitis of the bones of the skull and face may produce headache. Syphilitic periostitis or osteitis is now uncommon, but often involves the orbital bones. Mastoiditis is a common cause of bony pain. Frequently, in inflammatory involvement of the bones of the skull and orbit, there is localized pain and generalized headache. Malignant disease of the bone may similarly account for pain in the region of the lesion and generalized headache as well. Osteitis deformans and oxycephaly frequently are associated with generalized headache.
