Cross section of the posterior spiral vein (arrow) in the basal turn
https://www.utsouthwestern.edu/edumedia/edufiles/departments_centers/otolaryngology/fig.22.pdf
Cross section of the posterior spiral vein (arrow) in the basal turn. In this location the vein has virtually no bony covering. ST, scala tympani; MD modiolus.
Higher power view of osseous lamina and basilar membrane/organ of Corti in a preparation from an elderly individual in which there has been mild thinning of the myelinated nerve fibers within the osseous lamina

Higher power view of osseous lamina and basilar membrane/organ of Corti in a preparation from an elderly individual in which there has been mild thinning of the myelinated nerve fibers within the osseous lamina. The spirally oriented nerve fibers in the osseous lamina are nicely displayed in this …
Overview of veins in scala tympani
https://www.utsouthwestern.edu/edumedia/edufiles/departments_centers/otolaryngology/fig.18.pdf
Overview of veins in scala tympani. In this dissection, the osseous lamina and basilar membrane have been removed to provide a direct view into scala tympani (ST). The apical portion of the cochlea is shown in “A”. “B” shows the middle and upper basal turns. The arrows in “A” indicate the attachme…
Apical cochlear turn showing a Med-El electrode array inserted to near the apical tip of the basilar membrane (white arrow)

Apical cochlear turn showing a Med-El electrode array inserted to near the apical tip of the basilar membrane (white arrow). The black arrow indicates the apical-most electrode contact which is situated beneath the semi-transparent basilar membrane. From Wright CG, Roland PS. Temporal bone m…
Lower basal cochlear turn showing the common modiolar vein as it enters the cochlear aqueduct (arrow)
https://www.utsouthwestern.edu/edumedia/edufiles/departments_centers/otolaryngology/fig.24.pdf
Lower basal cochlear turn showing the common modiolar vein as it enters the cochlear aqueduct (arrow). The white arrow indicates the vestibulocochlear vein which joins the common modiolar vein. ST, floor of scala tympani.
This is a temporal bone which had an implant electrode inserted at the time that the bone was fresh and unfixed
https://www.utsouthwestern.edu/edumedia/edufiles/departments_centers/otolaryngology/fig.29.pdf
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 …

Cochlear dissection after insertion of an implant electrode array
https://www.utsouthwestern.edu/edumedia/edufiles/departments_centers/otolaryngology/fig.28.pdf
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 co…
Cochlear dissection after insertion of a perimodiolar type electrode array (Advanced Bionics standard Helix)
https://www.utsouthwestern.edu/edumedia/edufiles/departments_centers/otolaryngology/fig.10.pdf
Cochlear dissection after insertion of a perimodiolar type electrode array (Advanced Bionics standard Helix). Segments of the osseous lamina and basilar membrane have been removed to more clearly show the array in scala tympani. The apical portion of the silicone carrier is darkened due to osmium …
Dissection view of scala tympani and modiolus in the basal turn showing the posterior spiral vein (black arrows)
https://www.utsouthwestern.edu/edumedia/edufiles/departments_centers/otolaryngology/fig.23.pdf
Dissection view of scala tympani and modiolus in the basal turn showing the posterior spiral vein (black arrows). A vein (white arrow) on the side of the modiolus joins the posterior spiral vein. Compare this image with the modiolar cross sections seen in slide 14. This preparation received light…
