Some possible causes of SNHL:
- Ototoxic medication; medication that is toxic to hearing
- Familial or hereditary hearing loss
- Head trauma
- Malformation of the inner ear
- Exposure to loud noise
Sometimes a conductive hearing loss occurs in combination with a sensorineural hearing loss (SNHL). In other words, there may be damage in the outer or middle ear and in the inner ear (cochlea) or auditory nerve. When this occurs, the hearing loss is referred to as a mixed hearing loss.
