Complex frontal sinus fractures will often require elimination of the frontal sinus in order to re-establish an effective barrier between the external environment and the anterior cranial fossa
The frontal sinus is eliminated by sinus obliteration or cranialization, which can be differentiated on postoperative imaging based on whether the posterior table remains in situ
As a summary for frontal sinus fractures:
Describe anterior or posterior table involvement
Describe comminution and displacement
Raise concern for sinus outflow obstruction if there are displaced bone fragments obscuring the drainage pathway
