Spontaneous fracture of an ossified stylohyoid ligament.

The stylohyoid ligament extends from the styloid process to the hyoid bone. For an unknown reason it occasionally ossifies and forms a solid structure which can break because of trauma or even spontaneously. Symptoms of the fracture may mimic tumours, foreign bodies, infections or neuralgia. In our cases a spontaneous fracture of totally ossified stylohyoid ligaments presented as a painful neck swelling. The diagnosis was achieved by an ortopantomographic radiograph. In both cases the healing was spontaneous and complete.
