The use of homograft stapes

Homograft stapes were used for ossicular reconstruction in 43 ears over a three-year period. The average hearing improvement was 7.9 db. These cases were divided into groups: those with an intact posterior canal wall and those with an open mastoid cavity. The latter group fared better, with an average improvement of 15 db. Fourteen of the 43 ears were subsequently re-explored. Satisfactory bony union between the homograft stapes and recipient footplate was found in eight cases, four cases showed poor bony union, and bony resorption of the homograft had occurred in two patiemise for reconstruction of the ear with a loss of the stapes arch, especially in the presence of an open mastoid cavity and thus a shallow middle ear.
