B: Scanning micrograph of the under surface of the basilar membrane (BsM) and osseous lamina (OSL). The arrows indicate the spiral vessel beneath the basilar membrane, which is exposed to the perilymphatic space. From Roland PS, Wright C.G.

Another preparation in which an electrode array was inserted at the time the temporal bone was fresh and unfixed. After fixation and osmium staining, the array was removed from scala tympani. This SEM image shows the surface of the spiral ligament in an area where the array contacted the lateral wall. In the upper portion of the image the spiral ligament tissue is seen to be compressed and marked by grooves produced by the electrode. Below that area the normal porous surface of the spiral

This is a temporal bone which had an implant electrode inserted at the time that the bone was fresh and unfixed. After fixation, osmium staining, and dissection the electrode was removed from scala tympani. “A” shows the apical turn in an area that the electrode did not reach. The arrows indicate normal-appearing venules in the lower part of the spiral ligament. “B” shows an area in the basal turn where the electrode was in contact with the lateral wall immediately below the basilar

Cochlear dissection after insertion of an implant electrode array. Portions of the osseous lamina and basilar membrane have been removed to more clearly show the electrode lying in scala tympani. The silicone carrier of the array has been lightly stained with osmium so that it has a light brown color. Note that in the area indicated by the arrows the array is in direct contact with the lateral wall under the basilar membrane. From Roland PS, Wright C.G. Surgical aspects of cochlear
