Diagnosis and management of cochlear hydrops

Area of Science:

• Otolaryngology
• Neurotology
• Audiology

Background:

• Cochlear hydrops symptoms, like ear fullness and fluctuating hearing loss, can mimic other conditions.
• Tinnitus often accompanies cochlear hydrops attacks, resolving as hearing improves.
• The etiology of cochlear hydrops is often unclear, with standard neurotologic evaluations yielding negative results.

Purpose of the Study:

• To detail the etiology, physiology, diagnosis, and treatment of cochlear hydrops.
• To present a series of patients treated with the subarachnoid endolymphatic sac procedure.
• To evaluate the efficacy of surgical intervention for medically refractory cases.

Main Methods:

• Review of literature on cochlear hydrops and Ménière's disease.
• Clinical case series of patients undergoing subarachnoid endolymphatic sac surgery.
• Assessment of hearing stability and patient outcomes post-procedure.

Main Results:

• The subarachnoid endolymphatic sac procedure was performed on a small series of patients.
• Evidence suggests the shunt procedure stabilizes hearing in many patients.
• The procedure is considered for individuals refractory to medical management.

Conclusions:

• Cochlear hydrops is considered an early stage of Ménière's disease, potentially progressing to vertigo.
• Medical management typically involves diuretics, low-salt diets, and vasodilators.
• The subarachnoid endolymphatic sac procedure shows promise in stabilizing hearing for refractory cases.
