Key Points
- Sudden sensorineural hearing loss remains one of the most challenging
conditions in modern otology
- There is ambiguity in terms of its aetiology and management
- Sudden sensorineural hearing loss is often idiopathic
- We report temporospatial clustering of idiopathic sudden onset
sensorineural hearing loss in three cases
- Our findings add to the evidence that a transmissible agent such as a
virus underlies aetiology in at least a proportion of such cases
