The inner layer of the round window membrane is composed of mesothelial cells and this mesothelial cell layer extends to the scala tympani. This study describes the histopathologic findings of temporal bone analysis from a patient with bilateral perilymphatic fistula of the round window membrane. The left ear showed proliferation of mesothelial cells in the scala tympani of the basal turn adjoi...

Our aim was to elucidate the importance of anatomical aspects in planning local therapies for inner-ear diseases. The study undertakes the anatomical evaluation, from a surgical-approach perspective, of the relationship between the false and true round-window membranes. As our design, we chose a human temporal bone dissection study, for which we used 20 fresh temporal bones. After an explorator...
