[The use of autogeneic residual auditory ossicles, allogeneic auditory ossicles and the allogeneic nasoseptal cartilage in tympanoplasty].

OBJECTIVE

In search of ideal substance(s) for middle ear reconstruction, various materials were used and investigated in tympanoplasty.

METHOD: Up to may 1996, three kinds of materials were be used to reconstruct the ossicular chain: 1. Auto-ossicular residue reposition, 153 ears; 2. Homo-ossicle transplantation, 119 ears; 3. Homo-chondroseptum transplantation, 93 ears. We analysed and compared the middle and long-term results in these three groups.

RESULT: 1. In auto-ossicular residue reposition group, 86.3% was satisfied 10 years postoperation; 2. The satisfaction rate was 76.5% in homo-ossicle transplantation group; and 3. In the group of homo-chondroseptum graft, 77.4% of satisfaction rate was reached.

CONCLUSION

Auto-ossicular residue reposition is a better choice for ossicular chain reconstruction. That is responsible for its convenient, free of rejection, and better long-term results.
