Objective:
Sickle cell disease (SCD) is the most common hemoglobinopathy where morphologic changes to red blood cells affect the development of hard and soft tissues. The purpose of this study is to identify the craniofacial characteristics and maxillomandibular relationship in SCD patients and compare with unaffected subjects, through cephalometric radiographic assessment.
Materials And Methods:
The study included 44 Kuwaiti SCD patients (20 female, 24 male) as well as 44 age and gender matched controls. Digital lateral cephalometric, radiographs were recorded. SNA and ANB angles were measured and compared.
Results:
The mean SNA angle was found to be higher among the SCD cases (83.00 ± 3.22) than in controls (81.78 ± 4.58), but the difference was not statistically significant, (p = 0.146). The mean ANB angle in SCD cases (5.27 ± 2.36) was significantly higher, than that in controls (3.97 ± 2.23). The difference in means was statistically significant, (p = 0.01). Almost 50% of the SCD patients had class II malocclusion and 61.5% of the patients had prognathic maxilla.
Conclusions:
Patients with SCD in Kuwait exhibited characteristics of skeletal class II pattern malocclusion. They also showed evidence of compensatory maxillary expansion.

01:22Sutures of the Skull
Sutures are immobile joints between adjacent bones of the skull. The narrow gap between the bones is filled with dense, fibrous connective tissue that unites the bones. The long sutures located between the skull bones are not straight but instead follow irregular, tightly twisting paths. These twisting lines tightly...
