FIG. 7. a, b.

Right-sided type 5. Right-sided, typically deep and in most cases hidden and (without the decongestion) invisible horizontal basal crest, getting in a very close contact to the lateral nasal wall as getting deeper in the nose (a). Coronal MSCT scan clearly shows type 5. How deep the position of the deformity peak is can be easily assessed by looking at the anatomy of the orbit: only the orbital apex is presented in this scan, i.e. only the shadows of extra-ocular muscles, optic nerve is hardly visible, while the eyeball remained more anterior (b).
