[Current histopathological findings in Ménière's disease].

Controversy exists as to the presence of ruptures of the membranous labyrinth in patients with Meniere's disease, some authors considering the lesions reported to be artefacts only. Confirmation of the existence of healed labyrinthine tears was obtained in all cases of clinically and histopathologically confirmed Menière's disease studied by means of a protocol involving strict criteria. Lesions were observed mainly in Reissner's membrane and demonstrated three particular aspects. It is suggested that the images described by Out-Pouch in the posterior labyrinth are also the result of healed ruptures.
