Reversible Acute Sensorineural Hearing Loss Associated With Essential Thrombocytosis

• The isolated occurrence of reversible acute sensorineural hearing loss associated with thrombocytosis without other neurologic or hematologic manifestations has not been previously reported in the English literature, to our knowledge. We treated a patient with essential thrombocytosis who developed acute sensorineural hearing loss associated with marked thrombocytosis and in whom the hearing loss reversed after plateletpheresis.
