  • There is insufficient data on other mechanical methods of wax removal or on use of wax softeners to draw robust conclusions on their effectiveness

Ear wax only becomes a problem if it causes a hearing impairment or other ear related symptoms. The accumulation of wax occurs for many different reasons, including overproduction or underproduction of its constituent components, a failure to self clear because of slow skin migration, or mechanical issues such as the use of cotton buds or hearing aids. Wax may obscure the view of the tympanic membrane and may need to be removed for diagnostic reasons or for taking impressions before fitting a hearing aid or making ear plugs.
