In this procedure, a balloon catheter is placed in the eustachian tube through the nose, filled with saline, emptied, and removed. 2
What kind of tissue makes up the auditory tube?
Auditory Tube. Bone, cartilage, and fibrous tissue makes up the eustachian tube. Within the tube itself, there are also different surfaces, the upper portion of the tube is smooth, while the bottom portion of the tube contains cilia, or hair-like structures.
