An incus replacement prosthesis. The ossicle cup.
To achieve better hearing after incus replacement surgery, the ossicle-cup prosthesis is introduced. This prosthesis incorporates part of a Teflon Robinson's stapes prosthesis into the body of an incus. The ossicle-cup prosthesis has a dynamic joint with the stapes capitulum, as well as a variable height above the stapes. Preliminary hearing results of 45 cases show air-bone gap closure of 67% within 10 dB and 98% within 20 dB.
