FP02-8. RECONSTRUCTION OF THE OSSICULAR CHAIN WITH BONE CEMENT

Caglar Batman, Murat Sari (Marmara University School of Medicine, Turkey)

Objectives: The reconstruction of the ossicular chain has always been a problem in the middle ear surgery. The bone cement is a polymaleinate glass ionomer cement useful in ossiculoplasty procedures. To determine the feasibility of using bone cement in reconstruction of the ossicular chain and to evaluate the results, the ossicular chain was reconstructed by using bone cement in 122 cases undergoing middle ear surgery with ossicular chain defects.

Methods: Bone cement was used in 105 cases for incus long process to stapes suprastructure reconstruction in chronic otitis media; in 11 cases to apply teflon prosthesis to the newly reconstructed long process of incus as a revision stapedotomy; and in 6 cases for interposition of incus between malleus and stapes after traumatic ossicular chain dislocation. Preoperative audiograms were compared with audiograms 6-12 months after reconstruction.

Results: It has been observed that a considerable gain and a satisfactory closure of the air-bone gap is achieved with this method.

Conclusions: Our results with bone cement have shown that, it is a good reconstructive procedure and can be used successfully to reconstruct the middle ear ossicular chain. This study demonstrates the effectiveness of bone cement in the middle ear surgery.
