Conductive hearing loss is caused by a range of developmental, congenital or acquired pathology to the external, middle or inner ear.
Pathology
Essentially any process that obstructs or disrupts the passage of sound waves through the outer or middle ear can cause conductive hearing loss and the list of causes is very long. The most common are included below.
External ear
- external acoustic canal (EAC) atresia
- external acoustic canal tumours, e.g. cholesteatoma, squamous cell carcinoma
- trauma, e.g. tympanic membrane perforation (not seen radiologically)
- external acoustic canal foreign body
Middle ear
- middle ear tumours, e.g. glomus tympanicum, cholesteatoma, middle ear schwannoma
- trauma, e.g. ossicular chain disruption
- otomastoiditis
- Eustachian tube dysfunction
Inner ear
Treatment and prognosis
A stapes prosthesis may help improve conductive hearing loss.
