A 72-year-old man reports that his wife says he has hearing trouble.

The patient demonstrates signs of asymmetric sensorineural hearing loss (SNHL). In Weber test, sound localizes to the better ear in SNHL. Air conduction > bone conduction on Rinne test bilaterally supports SNHL. Audiometry is the best next diagnostic step to quantify and characterize the hearing loss.

Toronto Notes 2023 – ENT, " Hearing Loss " :

“Audiometry is the first-line investigation to distinguish conductive from sensorineural hearing loss and to assess severity and frequency involvement.”

MCCQE1 Objectives (Medicine > ENT > 20-1):

“Candidates must know the approach to hearing loss and interpret Weber and Rinne tests to guide investigations such as audiometry.”

Imaging (A, C) is reserved for red flags such as unilateral persistent SNHL, which may later prompt MRI to rule out acoustic neuroma. Wax removal (D) is for conductive loss. Hearing aids (E) are management, not diagnostic, and come after audiologic evaluation.
