Here is the diagram you are looking for:
This illustration (by Gralapp, from the Stanford Oto Surgery Atlas) shows exactly the arrangement tested in INICET May 2026:
Key anatomical points shown in the image:
- LVP (Levator Veli Palatini) - runs as a broad band on the posteromedial/inferior side of the Eustachian tube cartilage. It elevates the floor of the ET and moves the medial lamina toward the midline. The black arrows show how it compresses/opens the tube lumen.
- TVP (Tensor Veli Palatini) - lies on the anterolateral side, running inferiorly before hooking around the pterygoid hamulus. Its medial bundle (dilator tubae) is the PRIMARY dilator of the Eustachian tube.
- The red structure on the right is the internal carotid artery, a key surgical landmark.
Summary for exam:
| Feature | TVP | LVP |
|---|---|---|
| Position relative to ET | Anterolateral | Posteromedial/inferior |
| Innervation | V3 (mandibular n.) | CN X (vagus) via pharyngeal plexus |
| Primary role | Opens/dilates ET (via dilator tubae) | Elevates palate; assists ET opening |
| Hook around | Pterygoid hamulus | - |
TVP is the main muscle responsible for ET opening and middle ear ventilation.
