抽象
OBJECTIVE
The objective of this study was to analyze the neuro-otological findings in patients with delayed endolymphatic hydrops and compare them with audiovestibular abnormalities found in patients with idiopathic endolymphatic hydrops. Study design A retrospective open case study.
METHODS
A referral ambulatory dizziness clinic.
METHODS
Medical records of 30 patients with delayed endolymphatic hydrops and of 33 patients with idiopathic hydrops were analyzed. Outcome measures Clinical, electronystagmographic, caloric, and audiometric results in both groups of patients.
RESULTS
No differences in the prevalence of abnormalities on clinical testing, electronystagmography (including rotatory chair), or caloric testing were found between the groups. The clinical outcome of conservative therapy was better in patients with idiopathic endolymphatic hydrops (P =.03).
CONCLUSIONS
These findings are in keeping with the presumed common pathophysiology of delayed and idiopathic endolymphatic hydrops. However, it is important to identify patients with delayed hydrops in view of the chance of the potential poor response to medical therapy.
