Use of An Otoscope and Tuning Fork


LSU Physician Champion - Dr. Najy Masri


Weber Test


Weber Test – Place the vibratory tuning fork on top of the patient’s head or on the middle of their forehead and assess hearing through the left and right ears. A normal Weber test includes the ability to hear the sound through both ears. Patients with conductive hearing loss will hear fork louder in the affected ear and those with sensorineural hearing loss will hear the fork louder in the unaffected ear.




Rinne Test


Rinne Test – Place the vibratory tuning fork on the mastoid bone behind the ear. Remove once patient can no longer hear the sound and place close to the ear canal without touching. A normal Rinne test includes the ability to hear the sound longer through the air than through bone. Patients with conductive hearing loss hear bone transmission better and those with sensorineural hearing loss hear the fork better through air transmission.



Clinical Application


Conductive Hearing Loss – Can be seen in cerumen impaction, tympanic membrane perforation, otosclerosis, and cholesteatoma.

Sensorineural Hearing Loss – Can be seen in presbycusis, acoustic neuroma, Meniere disease, and exposure to loud sounds or certain medications.
