QuestionDo children with beta-thalassemia major (ages 5-15 years) who receive blood transfusions more frequently have fewer or less severe facial bone changes ("thalassemic facies") compared to those who receive transfusions less often? IntroductIonThalassemia, a hereditary hemoglobinopathy, imposes a significant burden on pediatric populations globally, particularly in Southeast Asia and the Indian subcontinent.Children with beta-thalassemia major often undergo regular blood transfusions from early infancy to manage chronic anemia and prevent growth failure and organ damage. 1,2owever, despite these interventions, these children frequently present with distinctive craniofacial anomalies that not only affect esthetics but also complicate orthodontic and surgical management, as well as affecting self-esteem.The expansion of bone marrow cavities in response to chronic anemia results in facial deformities-such as frontal bossing, depressed nasal bridge, maxillary overgrowth, and malocclusionclassically referred to as "chipmunk facies." 3 The relationship between transfusion frequency and the severity of craniofacial features remains inadequately understood, although preliminary data suggest that earlier and more regular transfusions may mitigate skeletal changes by suppressing compensatory erythropoiesis. 4,5iven the clinical importance of understanding this correlation, a systematic review of the existing literature was undertaken to synthesize findings from observational and cross-sectional studies investigating craniofacial growth disturbances in children with thalassemia in relation to their transfusion history.
Panigrahi et al. (Wed,) studied this question.
