MBBS QUESTION #10282
Question 1
On tuning fork testing, a patient's Rinne test shows bone conduction perceived louder/longer than air conduction (a 'negative' Rinne) in the affected ear, and the Weber test lateralizes to that same affected ear. This pattern indicates:
  • Conductive hearing loss in the affected ear✔️
  • Sensorineural hearing loss in the affected ear
  • Entirely normal hearing bilaterally
  • Sensorineural hearing loss in the opposite (unaffected) ear
Correct Answer Explanation
Normally air conduction exceeds bone conduction (positive Rinne). A negative Rinne (bone > air) indicates impaired sound transmission through the external/middle ear — conductive hearing loss — and in conductive loss the Weber test lateralizes toward (is heard louder in) the affected ear, since ambient masking noise is reduced there.
