Dissection of pharynx from left lateral approach

Auditory tube; levator veli palatini muscle, lateral view

The tensor veli palatini muscle (8) has been reflected anteriorly to expose the levator veli palatini muscle (20) as well as the cartilaginous and membranous parts of the auditory tube(5,6). The bursa between the tendon of the tensor veli palatini muscle and the pterygoid hamulus is visible at 9.
