Insights
Thalassemic children in the Indian subcontinent exhibit distinct cephalometric differences, including a shorter anterior cranial base and a retrognathic mandible. These findings suggest a Class II profile in affected individuals compared to controls.
Area of Science:
- Orthodontics
- Pediatric Hematology
- Craniofacial Development
Background:
- Thalassemia is a genetic blood disorder prevalent in the Indian subcontinent.
- Craniofacial abnormalities are potential complications of thalassemia.
- Understanding these cephalometric variations is crucial for managing thalassemic patients.
Purpose of the Study:
- To compare cephalometric characteristics of thalassemic children with a control group.
- To identify specific craniofacial differences in thalassemic children from the Indian subcontinent.
- To correlate cephalometric findings with the overall skeletal profile.
Main Methods:
- Cephalometric analysis was performed on 31 thalassemic children and matched controls.
- Measurements included anterior cranial base length, maxillary/mandibular angle, mandibular length, and SNB angle.
- Wiley's analysis was used to assess relative maxillary prognathism.
Main Results:
- Thalassemic children showed a shorter anterior cranial base length (Group I).
- A smaller maxillary/mandibular angle and shorter mandibular length were observed (Group II).
- The SNB angle was reduced, indicating maxillary prognathism in both male and female thalassemic subjects (Group III).
Conclusions:
- Thalassemic children present with a retruded maxilla and a retrognathic mandible.
- A Class II facial profile is characteristic of thalassemic individuals in this cohort.
- Cephalometric analysis highlights significant craniofacial alterations in thalassemic children.
Objectives:
To compare the cephalometric characteristics of thalassemic children in the Indian subcontinent with the controls, matched for sex and dental age.
Methodology:
A total of 31 thalassemic children were a part of the study. Cephalometric readings were recorded for the study and the control group.
Results:
Within the Group I stage, the anterior cranial base length was 68.40±2.93 mm, shorter when compared to the control group. In the Group II stage, the maxillary/mandibular angle was 31.58° for the case group and the mandibular length was shorter in comparison to the controls. In the Group III stage, the SNB angle was 76.42°, lesser than the control group. A relative maxillary prognathism of 9.88 mm and 12.85 mm was observed in thalassemic males and females respectively through the Wiley's analysis.
Conclusion:
The overall picture depicted a retruded position of the maxilla and a retrognathic mandible within the study group. A class II profile has also been observed among the study subjects.
