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

The 2024 STARS Summer Research Program for Teacher included seven teachers from Dallas-Fort Worth and surrounding areas. This 8-week program gave teachers an opportunity to work side-by-side with a faculty host. It consisted of activities, seminars, and an individualized research project that contributed to the advancement of science. The teachers were able to showcase and share these advancements during the end-of-program scientific poster session. STARS Summer Research Program for

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

A: Cross section showing a vessel (arrow) emerging from the edge of the osseous lamina. OC, organ of Corti; ST, scala tympani. 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.

The Department of Otolaryngology Residency Program was founded in 1958 under the supervision of Dr. Claude Winborn, Chief of UT Southwestern’s Otolaryngology service in the Department of Surgery.

Cochlear cross section showing the lower portion of the spiral ligament (SL) facing scala tympani (ST). The curved arrow indicates a venule coursing through the spiral ligament toward the floor of scala tympani. The straight arrow indicates the portion of the spiral ligament seen in the next image.

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 decalcification but no bone was removed from the modiolar wall. ST, floor of scala tympani.
