Okay, let's tackle this question about the type of deafness seen in the early stages of Meniere's disease. First, I need to recall what Meniere's disease is. It's an inner ear disorder causing vertigo, tinnitus, and hearing loss. The key here is to remember the pattern of hearing loss in the early stages.

Meniere's disease affects the labyrinth, which is part of the inner ear responsible for both hearing and balance. The early hearing loss is typically sensorineural. But wait, I should be precise. The specific type might be low-frequency sensorineural hearing loss. That's because the endolymphatic hydrops (fluid buildup) in Meniere's initially affects the base of the cochlea, which is responsible for low-frequency sounds.

Now, looking at the options. Let's assume the options are something like:
A. Conductive
B. High-frequency sensorineural
C. Low-frequency sensorineural
D. Mixed

If the correct answer is C, then the explanation would focus on how the cochlear dysfunction in Meniere's starts with low frequencies. Conductive is incorrect because there's no issue with the middle ear or ossicles early on. High-frequency loss would be more common in noise-induced or presbycusis. Mixed would combine both, which isn't typical early.

Clinical pearl: Remember that Meniere's early hearing loss is low-frequency, which is a key differentiator from other causes. Maybe use the mnemonic "MENIE" for Meniere's: M for Meniere, E for Endolymphatic, N for Nystagmus, I for Inner ear, E for Episodic vertigo. But the main point is the low-frequency SNHL.

I need to make sure the explanation is concise, covers the core concept, explains why each option is right or wrong, and includes a high-yield fact. Let me structure this properly in the answer.

**Core Concept**
Meniere’s disease is an inner ear disorder characterized by endolymphatic hydrops, leading to episodic vertigo, tinnitus, and progressive sensorineural hearing loss. Early auditory changes involve the **basilar membrane’s apical region**, affecting low-frequency sound perception due to fluid accumulation in the cochlea.

**Why the Correct Answer is Right**
In early Meniere’s disease, **low-frequency sensorineural hearing loss** (Option C) occurs because endolymphatic hydrops initially impairs the apical turn of the cochlea, which processes low-pitched sounds. This is confirmed by audiometric testing showing a "cookie-bite" pattern (gaps in low frequencies) in advanced stages but low-frequency loss early on. The pathophysiology involves disrupted ion balance and pressure changes in the endolymphatic compartment.

**Why Each Wrong Option is Incorrect**
**Option A: Conductive deafness** – Incorrect. Conductive loss involves middle ear dysfunction (e.g., otitis media), but Meniere’s affects the inner ear (sensorineural domain).
**Option B: High-frequency sensorineural hearing loss** – Incorrect. High-frequency loss is typical of noise-induced or age-related hearing loss, not Meniere’s.
**Option D: Mixed deafness** – Incorrect. Mixed patterns suggest combined middle and inner ear pathology, which is not characteristic of early Meniere’s.

**Clinical Pearl / High

✓ Correct Answer: B. Low frequency sensorineural hearing loss
