Leontiasis ossea

Leontiasis ossea

Leontiasis ossea, or lion face, is a term used to characterize an overgrowth of the facial and cranial bones that can be caused by several diseases. Although lion face is most frequently associated with craniofacial fibrous dysplasia, this condition can also be caused by Paget’s disease, fibrous dysplasia, hyperparathyroidism, and syphilitic osteoperiostitis.When a person has a disease that causes lion face, one or both maxilla will progressively grow, eventually affecting the eye orbits, mouth, nose and sinuses. Vision loss can result when the optic nerve is compressed by the overgrowth of bone; the bones can also interfere with breathing and eating. Rarely bones of the cranium can also be modified, which can cause cerebral pressure that can cause death.The overgrowth of bone can be treated with conservative surgical and Prosthetic techniques.
