Abstract

Objectives:

After tympanoplasty using a total ossicular replacement prosthesis, many unsatisfactory hearing results are due to dislocation of the prosthesis.

Material and methods:

We developed a cartilage guide for stabilising the total ossicular replacement prosthesis in the oval window niche. An oval-shaped piece of cartilage measuring 2.5 × 3.5 mm with a central hole was precisely punched out of a thin cartilage plate. The cartilage was placed in the oval niche, and its hole centred the prosthesis on the stapes footplate.

Results:

Hearing results in 52 patients confirmed acoustically the effectiveness of this method of total ossicular replacement prosthesis stabilisation on the stapes footplate. Subsequent ‘second-look’ surgery revealed stable ingrowth of the cartilage ‘shoe’ into the oval niche.

Conclusion:

Such a cartilage shoe might address one of the causes of unsatisfactory hearing following ossicular chain reconstruction with a total ossicular replacement prosthesis.
