Mechanical stability of new-generation meshes for M3 inguinal hernia repair: experimental pressure chamber testing of SWING-Mesh® and 3DMax™ MID Anatomical Mesh

SWING-Mesh failed to provide stability even under moderate intra-abdominal pressures, which questions its suitability for nonfixed repair of M3 hernias. 3DMax MID Anatomical Mesh demonstrated complete stability under both physiologic and supraphysiologic conditions, confirming the mechanical advantage of medium-weight 3D meshes. Implant design, weight, and stiffness appear more decisive for stability than fixation, supporting the selective use of nonfixation techniques when rigid meshes are applied.
