The efficacy of "conservative" medical regimens on the rate of hearing losses in Meniere's syndrome: a retrospective computerized statistical analysis.

The records of 47 patients with Ménière's syndrome were analyzed in a retrospective computerized study to determine the effect of different medical regimens on the long term course of hearing loss. Four treatment groups, including histamine (subcutaneous), other vasodilators (oral), vitamins, and untreated controls were examined. Results suggest that there was no statistically significant difference among the four groups in the rates or absolute level of hearing loss or SRT despite different therapeutic regimens. The ability of these agents to conserve hearing in patients with Ménière's syndrome remains unproven on the basis of clinical and laboratory evidence.

An experimental model for the study of endolymphatic hydrops in sharks: implications for the clinician.

In recent years, attention has focused on the role of the endolymphatic sac (ELS) and the endolymphatic duct (ELD) in the pathogenesis of endolymphatic hydrops (ELH). Changes have been noted surgically and radiographically by others in the ELS and ELD in patients with ELH. This report summarizes the development of a shark model with which to study the pathophysiology of ELH. The background material and overall results of anatomic, histopathologic, and ultrastructural studies using the model are presented. Possible implications for the clinical handling of ELH as a result of this work is emphasized.

Radiological visualization of the vestibular aqueduct. Technique and morphological features.

Thin-section tomography in the lateral and off-lateral projections permits radiographic visualization of the vestibular aqueduct, which is seen as an inverted J. The proximal curved portion has a constant configuration, while the distal straight portion varies according to the width of the external aperture and may be tubular, funnel-shaped, or filiform. Nonvisualization of the curved portion does not necessarily mean that it is not present.
