3D-Printed Microneedles Create Precise Perforations in Human Round Window Membrane in Situ

Conclusion: 3D-printed microneedles can create precise perforations in the HRWM without damaging intracochlear structures. As such, they have many potential applications ranging from aspiration of cochlear fluids using a lumenized needle for diagnosis and creating portals for therapeutic delivery into the inner ear.
