Summary
This study found that patients with sickle cell anemia, whether transfused or not, have normal auditory acuity and central auditory processing. Hearing function is not commonly impaired in sickle cell disease patients.
Area of Science:
- Audiology
- Hematology
- Neuroscience
Background:
- Sickle cell anemia (SCA) is a genetic blood disorder with potential systemic complications.
- Auditory function can be affected by various medical conditions, necessitating investigation in SCA.
Purpose of the Study:
- To evaluate auditory acuity and central auditory processing in patients with SCA.
- To compare auditory function between transfused, nontransfused SCA patients, and a control group.
Main Methods:
- Assessed pure tone air conduction thresholds and Speech Reception Thresholds.
- Utilized type A tympanograms to evaluate middle ear function.
- Administered the Competing Sentence Test and Binaural Fusion Test for central auditory processing assessment.
Main Results:
- All SCA patients exhibited normal pure tone thresholds and Speech Reception Thresholds.
- No significant differences in auditory function were observed among transfused, nontransfused, and control groups.
- All subjects presented with normal middle ear function (type A tympanograms).
Conclusions:
- Auditory acuity and central auditory processing appear to be preserved in patients with sickle cell anemia.
- Abnormal auditory function is not a prevalent issue in individuals with sickle cell disease.
