Evaluation of Mandible Fractures in Patients With Sickle Cell Anemia-A Nationwide Study.

PURPOSE: Sickle cell anemia is the most commonly inherited blood disorder in the United States. Despite its prevalence, clinicians know little about the extent of its impact on orofacial manifestations.

MATERIALS AND

METHODS

All patients with diagnoses of mandible fracture and sickle cell anemia admitted from 2004 through 2014 were identified using the National Inpatient Sample. Patient demographics, fracture regions, and complications were characterized by descriptive statistics.

RESULTS

Fifty-one of 48,464 patients admitted for mandible fracture had sickle cell anemia. The mean age of the identified patients was 25 years (range, 4 to 58 yr). Of all admitted patients, mandible angle fracture was the most common (19%), followed by fracture of the body of the mandible. Seventy-five percent of cases reviewed were treated with open reduction and internal fixation.

CONCLUSIONS

Most mandible fractures in patients with sickle cell anemia were located in the angle of the mandible. Complications were minimal and outcomes were satisfactory. Aseptic necrosis of the jaw was a frequent complication of mandible fracture in patients with sickle cell anemia. These results provide clinicians with a better understanding of the distribution and hospital course of patients with sickle cell anemia and facial fractures.
