Which clinical feature best distinguishes Ménière disease from sudden sensorineural hearing loss (SSHL)?

Explanation

## Distinguishing Ménière Disease from Sudden Sensorineural Hearing Loss ### Clinical Presentation Pattern **Key Point:** The defining discriminator between Ménière disease and SSHL is the **episodic, recurrent nature** of Ménière disease versus the **acute, non-recurrent presentation** of SSHL. ### Comparison Table | Feature | Ménière Disease | Sudden Sensorineural Hearing Loss | |---------|-----------------|-----------------------------------| | **Onset** | Episodic, recurrent over months/years | Acute, single event | | **Vertigo** | Present (classic triad) | Absent or minimal | | **Hearing loss pattern** | Fluctuating, low-frequency initially | Sudden, fixed, any frequency | | **Tinnitus** | Present, fluctuating | May be present | | **Aural fullness** | Present (pathognomonic) | Absent | | **Course** | Multiple attacks with symptom-free intervals | No recurrence; recovery or permanent loss | | **Duration of attack** | 20 min to several hours | Develops over hours to days | ### Why Recurrence Matters **High-Yield:** Ménière disease is characterized by **recurrent, unpredictable episodes** separated by symptom-free intervals. This episodic pattern is the hallmark that separates it from SSHL, which presents as a **single acute event** with no recurrence. **Clinical Pearl:** A patient with a second episode of vertigo + hearing loss + tinnitus months after the first episode has Ménière disease until proven otherwise. SSHL does not recur. ### Why Other Features Are Not Discriminatory - **Vertigo with hearing loss:** Both conditions can present with vertigo and hearing loss; SSHL may have mild vertigo. - **Low-frequency hearing loss:** While Ménière typically shows low-frequency loss initially, SSHL can also affect low frequencies. - **Unilateral sensorineural hearing loss:** Both are unilateral conditions; this is not discriminatory.
