Where does the NP first place the tuning fork when conducting the Rinne test?

In the Rinne test, the tuning fork is first placed behind the ear on the mastoid bone. This location is critical because it allows the examiner to assess bone conduction of sound. The test specifically evaluates how well sound travels through the bones of the skull compared to air conduction, which is tested by placing the fork in front of the ear shortly after.

By beginning behind the ear, the clinician can determine how long the sound is heard through bone conduction before it fades. This comparison provides valuable insights into potential conductive or sensorineural hearing loss based on the patient's ability to perceive sound through different conduits. The rationale behind this method makes it easy to interpret results and guide further hearing evaluations or interventions.
