## **Core Concept**
Meniere's disease is a disorder of the inner ear that affects balance and hearing. The condition is characterized by a classic triad of symptoms. Understanding the pathophysiology and clinical presentation of Meniere's disease is crucial for diagnosing and managing the condition.

## **Why the Correct Answer is Right**
The classic triad of Meniere's disease consists of **vertigo**, **tinnitus**, and **hearing loss** (typically low-frequency sensorineural hearing loss). The fourth symptom often associated with Meniere's disease is **aural fullness** or ear fullness. Therefore, the correct answer is related to the symptom not included in the classic triad.

## **Why Each Wrong Option is Incorrect**
- **Option A:** Vertigo is a key component of Meniere's disease, presenting as episodic vertigo.
- **Option B:** Tinnitus, or ringing in the ears, is another critical symptom of Meniere's disease.
- **Option C:** Hearing loss, particularly fluctuating low-frequency sensorineural hearing loss, is a hallmark of Meniere's disease.
- **Option D:** Aural fullness is indeed a symptom associated with Meniere's disease but is sometimes considered the fourth symptom rather than part of the classic triad.

## **Clinical Pearl / High-Yield Fact**
A key clinical pearl for Meniere's disease is that the condition often presents with a **fluctuating hearing loss**, particularly in the low-frequency range. This is a distinguishing feature from other causes of hearing loss. Mnemonically, the classic triad can be remembered as "VTH" (Vertigo, Tinnitus, Hearing loss), with aural fullness being the commonly associated fourth symptom.

## **Correct Answer:** D. Aural fullness.
