Polymeric microneedles fabricated via two‐photon polymerization (2PP) lithography enable safe medical access to the inner ear. Herein, the material class for 2PP‐lithography‐based microneedles is expanded by pyrolyzing 2PP‐fabricated polymeric microneedles, resulting in glassy carbon microneedles. During pyrolysis the microneedles shrink up to 81% while maintaining their complex shape when the exposed surface‐area‐to‐volume ratio (SVR) is 0.025
