When should tympanometry not be performed?

Tympanometry is a test used to assess the condition of the middle ear and the mobility of the eardrum by creating variations in air pressure. It is important to recognize the situations in which tympanometry should not be performed to ensure patient safety and accuracy of results.

In the case of otitis externa, pain, or discharge, tympanometry should be avoided. This is because the presence of an infection or inflammation in the ear canal can lead to inaccurate test results. Additionally, any manipulation in the ear canal during the test could cause discomfort or exacerbate the existing condition. Therefore, performing tympanometry in these circumstances could potentially harm the patient and yield misleading information regarding their middle ear function.

The other situations, such as ear wax removal or routine checkups, do not inherently contraindicate tympanometry, and its application might vary based on the clinician's assessment. Patients with normal hearing can also undergo tympanometry as part of a comprehensive hearing evaluation, particularly if there are concerns about middle ear function, making this test valuable even in those cases.
