What is Vaso-Occlusion

Sickle cell disease (SCD) is an autosomal recessively inherited group of red blood cell disorders. It is more commonly found in African Americans and Hispanics in the United States. The sickle-shaped cells characteristic of the disease cause physiological problems, including hemolytic anemia and vaso-occlusion. Research has linked hearing loss to sickle cell disease. Studies have shown that children and adults with sickle cell disease may have higher rates of sensorineural and central auditory hearing impairment. This case study examines hidden hearing loss in an African American boy with SCD who presents with normal hearing thresholds. It also discusses the role of audiologists in the care of individuals with sickle cell disease and hearing loss.
