Thalassaemia, a genetic blood disorder, causes haemolytic anaemia due to defective haemoglobin chain synthesis. This leads to bone changes and organ hypertrophy, but typically requires no specific maxillofacial or dental treatment.
Area of Science:
- Hematology
- Genetics
- Pathology
Background:
- Thalassaemia results from impaired alpha or beta-globin chain synthesis, crucial for haemoglobin formation.
- The primary clinical manifestation is haemolytic anaemia, characterized by premature red blood cell destruction.
- Chronic anaemia stimulates erythropoiesis, leading to secondary effects like bone deformities and organ enlargement.
Purpose of the Study:
- To describe the aetiology and primary clinical features of thalassaemia.
- To outline the pathophysiological consequences of haemolysis in thalassaemia.
- To detail the characteristic radiographic findings, particularly in bone structure.
Main Methods:
- Review of the pathophysiology of thalassaemia.
- Analysis of clinical manifestations and their link to haemolysis.
- Correlation of erythropoietic stimulation with morphological bone changes.
Main Results:
- Defective haemoglobin synthesis leads to haemolytic anaemia.
- Stimulated erythropoiesis causes significant morphological changes in bone, including facial bones.
- Radiographic evidence shows reduced cortical thickness and trabecular bone density.
Conclusions:
- Thalassaemia's core issue is defective haemoglobin synthesis, causing anaemia and subsequent bone pathology.
- Radiographic findings highlight skeletal involvement, including the facial bones.
- Maxillofacial and dental interventions are generally not primary treatment concerns for thalassaemia itself.

Pulmonary Angiogram
A Pulmonary Angiogram is an invasive procedure involving injecting a contrast medium through a catheter threaded into the pulmonary artery or the right side of the heart to visualize the pulmonary vasculature. Computed Tomography (CT) scans have mainly replaced this...

Definition and Purpose
An X-ray, or radiograph, is a non-invasive method that uses ionizing radiation to take images of internal structures. It is mainly used in cardiac imaging to examine the heart, lungs, and major blood vessels, aiming to identify abnormalities in the heart's size, shape, and position, such as heart failure, congenital defects, and vascular...
