FP02-10. INCUDOSTAPEDIAL RECONSTRUCTION OSSICULOPLASTY WITH BONE CHIPS AND PASTE

Etsuo Yamamoto, Hiroyuki Oiki (Yamamoto Surgicenter, Japan)

Objectives: This study reports the author's technique and hearing results with bone chips and paste reconstruction of the incudostapedial disruption.

Method: Bone chips and paste were taken from the mastoid cortex which is exposed following postauricular skin incision. Bone chips and paste were placed on the defective area between the long process of the incus and the head of stapes and fixed with adhesive.

Results: Our postoperative hearing results were quite satisfactory. The postoperative air - bone gaps were within 10dB in 13ears (56.5%), 15dB in 19ears (82.6%) and 20dB in 22 ears (95.7%) out of all 23 ears operated. The mean preoperative and postoperative air- bone gaps were 28.6 and 9.7 dB, respectively.

Conclusions: Our method using bone chips and paste is useful and safe for the repair of the eroded long process of the incus and yields good hearing results in selected patients.
