Crumple zone effect of nasal cavity and paranasal sinuses on posterior cranial fossa

Objectives/Hypothesis Examine a protective crumple zone effect of paranasal sinuses and nasal cavity on skull base fractures. Study Design Randomized‐control, cadaveric study. Methods In the experimental group (n = 4), the nasal cavity and bilateral sinuses of cadavers were obliterated with bone cement, whereas the control group (n = 4) had native sinus architecture. Increasing frontal, glabellar impacts were introduced. Each impact event was...
