H. Silverstein et al., Dexamethasone inner ear perfusion for the treatment of Meniere's disease: A prospective, randomized, double-blind, crossover trial, AM J OTOL, 19(2), 1998, pp. 196-201
Objective: To investigate the benefits of intratympanic administration of d
examethasone in the treatment of unilateral Meniere's disease, with particu
lar attention to the symptoms of hearing loss and tinnitus.
Study Design: A prospective, randomized, double-blind, crossover study comp
aring improvements in hearing loss, tinnitus, aural Illness, and caloric ve
stibular response secondary to intratympanic dexamethasone and sodium hyalu
ronate injection versus placebo consisting of saline and sodium hyaluronate
.
Setting: A private otology/neurotology practice.
Patients: Twenty patients diagnosed with either definite or probable Menier
e's disease as defined by the American Academy of Otolaryngology Head and N
eck Surgery Committee on Hearing and Equilibrium. All patients were greater
than or equal to 21 years old and were not receiving any other form of tre
atment for their Meniere's disease. Each patient's primary symptoms of conc
ern were hearing loss, aural fullness, and roaring tinnitus.
Interventions: Three consecutive daily administrations of intratympanic dex
amethasone or placebo to the involved ear.
Main Outcome Measures: Changes in audiometric pure-tone averages, speech re
ception thresholds, caloric vestibular responses, scores on the tinnitus ha
ndicap inventories, questionnaires, and telephone interview responses.
Results: No significant changes were observed in any measured parameter. Pa
tients were unable to consistently identify which medication was dexamethas
one and which was placebo.
Conclusions: Intratympanic administration of dexamethasone in a group of pa
tients with unilateral Meniere's disease (Shea's stage IV) showed no benefi
t over placebo for the treatment of hearing loss and tinnitus.
