The aim of this study was to evaluate the perilymphatic pressure, by means of the MMS-10 Tympanic Displacement Analyzer (TDA), in patients with Meniere's disease (MD). Measurements were performed in 37 patients with MD and in 14 normal-hearing subjects. Data were collected from 3 groups: healthy ears of normal-hearing subjects, unaffected ears of patients with MD, and affected ears of patients with MD. Analysis of the results obtained with the TDA showed no significant differences between the 3 groups. Several hypotheses could explain this lack of difference: 1) perhaps indirect measurement of perilymphatic pressure with the TDA is not relevant; 2) perhaps hyperpressure of the inner ear is not the physiological basis for the clinical triad of MD; or 3) perhaps endolymphatic hydrops does not produce changes in perilymphatic pressure. The results of this series indicate that the TDA is not useful in the evaluation of patients with MD.

Article Synopsis
- * The patient's audiological assessments showed low-frequency conductive hearing loss (CHL) but normal impedance, with additional vestibular abnormalities indicative of a problem similar to Meniere's disease.
- * After diagnosing the DAVF via MRI and angiography, the patient underwent a successful trans-arterial embolization treatment, which removed the symptoms and resolved the low-frequency air-bone gap, suggesting intracranial pressure issues might affect inner ear fluid dynamics.

A perilymphatic fistula (PLF) presents with abnormal traffic in the otic capsule, causing cochlear and vestibular symptoms. However, the mechanisms underlying symptom recurrence remain controversial. Herein, we report the case of a 27-year-old female who complained of hearing disturbance in her right ear and recurrent vertigo after sudden onset of hearing loss with vertigo.
