Malleostapedotomy in Patients With Stapes Fixation: A Systematic Review

open access: yesThe Laryngoscope, EarlyView.
This systematic review analyses the current evidence on malleostapedotomy as a primary or revision procedure in patients with stapes fixation. Twenty‐five studies comprising 632 operated ears were included. Malleostapedotomy proved to be a safe and effective alternative to incus‐anchoring stapedoplasty, with favorable hearing outcomes and a low ...

Stimuli‐Responsive 3D‐Printed Structurally Colored Materials Based on Core–Shell Particle Architectures

open access: yesMacromolecular Materials and Engineering, EarlyView.
A novel, structurally colored and pH‐responsive filament for FDM 3D‐printing is presented, which is based on tailored core–shell particles with methacrylic acid as a comonomer in the particle shell. The pH‐responsiveness of the printed objects is achieved due to particle swelling in alkaline conditions.
