Bone and maxillofacial abnormalities in thalassemia: a review of the literature.

ABSTRACT

Thalassemia is an inherited blood disorder due to an imbalanced globin chain synthesis leading to anaemia that requires regular blood transfusions and iron-chelating therapy. Of all organ failures secondary to iron deposit, and all the complications, heart failure still represents the first cause of death. Osteopenia and osteoporosis can be considered important causes of morbidity in a population whose lifespan is getting longer, with a strong impact on their quality of life. Authors have reported mainly bone, oral and maxillofacial abnormalities and relative complications, especially in terms of traumatic risk, in patients affected by thalassemia. As examples, this study reports bone modifications in three clinical cases; one of these was also complicated with a femoral fracture, surgically treated with the same criteria of metastatic femoral bone disease. More research on this topic is necessary for the prevention of several complications caused by this disease, and to carefully plan dental or traumatologic operations.
