Summary
This study highlights a potential link between macrocytosis, characterized by large red blood cells, and sudden sensorineural hearing loss. Further research is needed to explore this connection.
Area of Science:
- Otolaryngology
- Hematology
- Hepatology
Background:
- Sudden sensorineural hearing loss (SSNHL) can be associated with various blood disorders.
- However, macrocytosis has not been previously recognized as a direct cause of SSNHL.
Observation:
- A case of bilateral sequential SSNHL is presented in a patient with marked macrocytosis (mean corpuscular volume 124 fL).
- The macrocytosis was attributed to alcohol-induced liver dysfunction.
Findings:
- This case suggests a potential association between macrocytosis and SSNHL.
- A possible pathophysiological mechanism connecting these conditions was identified.
Implications:
- This finding expands the differential diagnosis for SSNHL.
- Further investigation into the link between macrocytosis and hearing loss is warranted.
