abstract = {Efficient computational approaches are crucial for
advancing computational fluid dynamics (CFD)-based automated
planning in nasal surgeries, such as septoplasties and
turbinectomies. This study introduces a hybrid
lattice-Boltzmann and level-set method to address the
trade-off between computational cost and automation. By
interpolating geometry variations in discrete steps between
pre-surgical and target states, the approach achieves
computational efficiency with only 21 surface variations per
intervention. Previous methods rely on more costly coupling
strategies, such as reinforcement learning or thermal
modeling, which may still be appropriate for complex
planning scenarios involving multiple intervention sites or
thermal flow analysis. In contrast, the presented method
reduces complexity while retaining key predictive
capabilities, making it particularly suitable for
widespread, time-sensitive clinical use focused on a single
surgical intervention. Fluid mechanical metrics, including
pressure loss and volume flow rate balance, are evaluated
alongside tissue removal volume to recommend optimized
surgical plans. Case studies on three patients demonstrate
tissue savings of $12–25\%$ without compromising key flow
parameters. Additionally, a non-linear regression model
trained on as few as 11 CFD simulations predicts pressure
loss and flow rates with errors below $4\%,$ and reduces
computational costs by $50\%.$ The proposed framework
represents a significant step toward making CFD-based
virtual nasal surgery planning more accessible and
practical.},
