The evaluation of cerumen impaction begins with a history and physical exam.

Physical findings of cerumen impaction may include:

• Plugged ear canal
• Inability to see the eardrum on the affected side.

Tests that may be used to evaluate cerumen impaction include:

• Culture of the fluid draining from the canal
• Many people can detect this problem at home. An inexpensive otoscope can be purchased at most pharmacies for under $20.00. With a little practice, it is easy to see when the canal is blocked with wax.
