John S. Rhee, MD, MPH, and colleagues use computational fluiddynamics (CFD) and virtual surgery (VS) to assess functional outcomes of nasal surgery. They generated 3-dimensional models of the nasal airway using presurgical and postsurgical computed tomographic images, which they then digitally altered to generate different changes in the nasal anatomy. When comparing these models with presurgical images, they found that the postsurgical CFD analysis on all VS models predicted similar reduction in overall nasal resistance, as well as more balanced airflow distribution between sides. However, inferior turbinate reduction alone produced little positive change. This may be a helpful tool to enable surgeons to predict how much a patient may benefit from nasal surgery.
