Summary
Sickle cell anemia can affect hearing in children. This study found a higher incidence of hearing loss in sickle cell patients, with some cases possibly linked to central nervous system involvement.
Area of Science:
- Audiology
- Hematology
- Pediatrics
Background:
- Sickle cell anemia is a genetic blood disorder.
- Auditory complications in sickle cell anemia are not well-documented.
Purpose of the Study:
- To investigate the prevalence of hearing loss in children with sickle cell anemia.
- To explore potential links between hearing deficits and central nervous system involvement in these patients.
Main Methods:
- Audiologic and otologic examinations were conducted.
- 43 children (ages 7-18) with sickle cell anemia were compared to 23 age-matched controls.
Main Results:
- 88% of sickle cell patients had normal hearing; 12% exhibited mild high-frequency sensorineural hearing loss.
- No hearing loss was observed in the control group.
- Three of five patients with hearing loss showed signs of central nervous system involvement (p < 0.025).
Conclusions:
- Children with sickle cell anemia have a higher incidence of hearing loss than controls.
- Periodic hearing evaluations are recommended for early detection of auditory complications and potential CNS involvement.
