Project Description

This illustration depicts the anatomy of the eustachian tube (ET) in relation to skull base structures. Medical students find this topic challenging to learn as the relationships are not readily identifiable during dissection. A left inferolateral view of the skull (with lower jaw removed) offers a unique oblique depiction of the course of the left and right cartilaginous parts of ETs in relation to skull base foramina and the pterygoid plates. In both views, the temporal bone is semi-transparent to reveal schematic versions of the underlying cavities to which the ET connects. The left inferior view on the right side of the piece reveals the ET’s ostium on the lateral wall of the nasopharynx, which is sectioned at the level of the hard palate. This offers a visual connection between the mucous membrane-lined ET and traditional depictions of the ET that are often limited to the cartilaginous structure.
