Genetic algorithm-based optimization of columella shape with FEM surrogate modeling: convergence analysis and application to ossicular chain reconstruction
This study develops a hybrid optimization framework integrating genetic algorithms (GA) with machine learning-trained finite element (FE) surrogate models for designing middle ear columella prostheses. It aims to enhance acoustic performance, reduce computational load, and provide efficient design strategies for ossicular chain reconstruction. The framework achieved over 1000-fold acceleration, identifying optimal low-density, moderately stiff materials (like cartilage) and tapered geometries for improved high-frequency sound transmission. It also revealed multimodal design landscapes, emphasizing global search. This scalable approach supports patient-specific customization and efficient design-space exploration, with potential to improve otologic surgery outcomes.

Material & Geometry Optimization Insights
The optimized prosthesis designs consistently favored low-density (1000–1600 kg/m³) and moderately stiff (2–6 MPa) materials, aligning with clinical preferences for cartilage.
Geometries with smaller cross-sectional areas and tapered shapes consistently improved high-frequency sound transmission, confirming the importance of precise geometric tuning to align with middle ear biomechanics.
The framework also revealed multimodal design landscapes, underscoring the importance of global search strategies to avoid local minima, especially in IIIi-M and IVi-M configurations.
