抄録
Long-term observations on the ceramic ossicular replacement prosthesis (CORP) were performed. The extrusion rates were 8.3% for CORP-P (partial) and 5.2% for CORP-T (total), most extrusions occurring within 2 years. The hearing results were satisfactory. An air-bone gap at 1 year was within 20dB in 74.0% with CORP-P and 54.5% with CORP-T, and at 3-5 years 66.7% and 53.3%, respectively. It was confirmed that the short-term results were maintained even for a long period of time. The main cause of unsatisfactory hearing gain was the displaced or extruded CORP. To prevent them, in addition to the fixation of CORP with a cartilage plate, making a dimple in the end of the shalft of P type, fixing of the shaft of T type with fascia, and additional fixation of the CORP head with the malleus handle and chorda tympani nerve were found advisable.
