Eardrum perforations are treated via tympanoplasty surgical procedures
Currently only 1 out of 9 patients with eardrum perforations proceed with tympanoplasty procedures due to cost and invasive nature of surgery
A novel three-dimensionally printed tympanic membrane graft from a specialized biodegradable ink, which can repair damaged eardrums and passively enhance sound conduction.
Tympanic membrane grafts can be manufactured using 3D printing
Acoustic properties of 3D grafts are uniform, reproducible and similar to human TM
Mechanical properties of 3D grafts are resilient following stress
3D graft scaffold architecture influences acoustic and mechanical properties
3D printed TMs enable the focused study of discrete biomechanical properties
