A middle aged women presented with right sided hearing loss Rinne’s test shows positive result on left side and negative result on right side. Weber’s test showed lateralization to left side,diagnosis is –
## **Core Concept**
The question involves interpreting the results of hearing tests, specifically Rinne's test and Weber's test, to diagnose the type of hearing loss in a patient. Rinne's test compares air conduction (AC) and bone conduction (BC) in one ear, while Weber's test assesses lateralization of sound. The patient's presentation suggests a unilateral hearing loss with specific test results.
## **Why the Correct Answer is Right**
The patient's symptoms and test results indicate a conductive hearing loss on the right side.
- Rinne's test is positive in normal individuals and those with sensorineural hearing loss (SNHL), but negative in conductive hearing loss (CHL), where BC > AC.
- A negative Rinne's test on the right side suggests CHL on that side.
- A positive Rinne's test on the left side indicates normal hearing or SNHL, but given the context, it supports that the left ear is normal.
- Weber's test lateralizing to the left (better-hearing ear) also supports a conductive loss on the right side, as sound lateralizes to the affected ear in CHL and to the better ear in SNHL.
## **Why Each Wrong Option is Incorrect**
- **Option A:** This option is incorrect because it does not match the clinical presentation and test results indicative of conductive hearing loss on the right side.
- **Option B:** This option might seem plausible but does not accurately reflect the diagnosis based on the provided test results.
- **Option D:** This option is incorrect as it does not align with the test results provided, specifically the implications of Rinne's and Weber's tests.
## **Clinical Pearl / High-Yield Fact**
A key point to remember is that in conductive hearing loss, Rinne's test is negative (BC > AC), and Weber's test lateralizes to the affected ear. This helps differentiate conductive from sensorineural hearing loss, where Rinne's is positive, and Weber's lateralizes to the better-hearing ear.
## **Correct Answer:** . Conductive hearing loss right ear.
