Reversible acute sensorineural hearing loss associated with essential thrombocytosis

Area of Science:

• Hematology
• Otolaryngology
• Neurology

Background:

• Essential thrombocytosis is a myeloproliferative neoplasm characterized by elevated platelet counts.
• Sensorineural hearing loss can have various causes, including vascular and hematologic factors.

Observation:

• A case of acute sensorineural hearing loss occurred in a patient with essential thrombocytosis.
• The patient presented with marked thrombocytosis but no other neurological or hematological abnormalities.

Findings:

• The hearing loss was acute and sensorineural in nature.
• A direct correlation was observed between the degree of thrombocytosis and the severity of hearing loss.
• Hearing function was restored following plateletpheresis, indicating the reversible nature of the condition.

Implications:

• This case suggests a potential link between thrombocytosis and reversible sensorineural hearing loss.
• Plateletpheresis may be a therapeutic option for hearing loss associated with severe thrombocytosis.
• Further research is warranted to elucidate the underlying mechanisms and clinical significance.
