Anything that completely blocks the ear canal can cause hearing loss. Blockage with earwax (also called cerumen) is common.
Many other problems can block the ear canal and lead to hearing loss. Such blocking causes a decrease in volume but does not generally produce distortion. These problems include:
- Infections with swelling that shuts the ear canal
- Foreign bodies in the ear
- An injury
- Birth defects
- A growth in the ear canal

What are genetic causes of deafness?
Deafness is an etiologically heterogeneous trait with many known genetic and environmental causes. Genetic factors account for at least half of all cases of profound congenital deafness, and can be classified by the mode of inheritance and the presence or absence of characteristic clinical features that may permit the diagnosis of a specific form of syndromic deafness. The identification of more than 120 independent genes for deafness has provided profound new insights into the pathophysiology of hearing, as well as many unexpected surprises. Although a large number of genes can clearly cause deafness, recessive mutations at a single locus, GJB2 or Connexin 26, account for more than half of all genetic cases in some, but not all populations.
