Sudden sensorineural hearing loss in haemoglobin SC disease.

Presented herein is a case report of sudden sensorineural hearing loss in the setting of haemoglobin SC disease. The relationship of the two is rare; the authors have found that this is only the second report in the literature. In this instance, partial exchange transfusions were performed in an attempt to decrease viscosity and improve blood flow. Thereafter, hearing stabilized and then slowly improved. The evidence for the beneficial role of these transfusions in this setting is, at best, circumstantial, but it is theoretically sound and worthy of further study.
