A questionnaire was sent to 100 consultant otolaryngologists from three sel
ected health regions in the United Kingdom enquiring about their assessment
and management of a patient presenting with sudden-onset sensorineural hea
ring loss. Seventy-six replied, of whom 42 stated a sub-specialist interest
in otology. Seventy-eight per cent of respondents would order routine bloo
d tests including the erythrocyte sedimentation rate (ESR) and syphilis ser
ology; in addition 38 per cent would order a magnetic resonance image (MRI)
scan at the first presentation. The vast majority would treat such a patie
nt (89 per cent), although the method and combination varied widely. A revi
ew of the literature confirmed that the level of evidence for treating this
condition is limited and therefore the wide disparity in consultants' prac
tice is not surprising.
