Anatomy - Nasal Cavity

Good to know in advance:
The anatomy of the paranasal sinuses is complex, with specific structures involved in multiple processes. The many normal variants, with their surgical implications, also make structuring this module challenging. Ultimately, the choice was made to repeat or revisit specific anatomical structures multiple times to keep the module understandable and organized. The textual overlap is kept minimal and should not be too disruptive.
