## Resource

Daniel Grafton is a public health specialist with the UN who taught himself computational fluid dynamics (CFD) after 9 soft tissue surgeries failed to fix his sleep-disordered breathing. In this episode, Daniel runs CFD on Ron's pre and post-MSE CBCTs, revealing pressure maps, velocity data, wall shear stress, and turbulence patterns a standard CBCT cannot show.
