Endolymphatic sac decompression surgery in Meniere's disease aims to control which symptom primarily?
- A Tinnitus
- B Vertigo spells ✓
- C Sensorineural hearing loss
- D Aural fullness
Correct answer: B. Vertigo spells
Explanation
Endolymphatic sac decompression (ELS surgery) is performed to reduce the frequency and severity of episodic vertigo spells in Meniere's disease by decompressing the endolymphatic sac and improving endolymph drainage. It is a hearing-preserving procedure. Tinnitus and aural fullness may improve as secondary benefits, but the primary indication is disabling vertigo refractory to medical management. Sensorineural hearing loss is the most difficult symptom to reverse.
