BACKGROUND: Characteristic features of @entity5479 are destruction of the bone and a high tendency for recurrent disease. The choice of surgical procedure is determined by audiological results and the rate of recurrent @entity3540 . @entity1 : One hundred fifty @entity1 who underwent primary @entity3540 surgery were investigated 3-5 years postoperatively. Preoperative and postoperative audiological results and rate of revision surgery were compared for the respective surgical procedures. All @entity3540 were treated with an open surgical technique. The lateral attic walls and @entity3540 were removed. RESULTS: Cholesteotoma recurred in 15 @entity1 (10%). Primary reconstruction of the ossicular chain with a tympanoplasty (type III) was performed in 98 @entity1 in the first operation. Approximately 80% of @entity1 treated with a type III tympanoplasty had a maximum postoperative air-bone gap of 20 dB in the main speech range, depending on the frequency. In about 50% of @entity1 , this value was 10 dB or less. Comparison of preoperative and postoperative conductive @entity393 between 250 Hz and 8000 Hz revealed an improvement (p < 0.05) of 10 dB (500 Hz, 3000 Hz, 4000 Hz) and 15 dB (250 Hz, 1500 Hz, 2000 Hz, 8000 Hz). CONCLUSIONS: In our opinion, a second look operation should be performed in cases where a large @entity3540 cannot be removed with sufficient reliability. This applies especially to a @entity3540 in the oval window. Here, we suggest second-look surgery after one year.
