Stapes surgery: outcome evaluation.
23 patients were studied preoperatively, 17 at 2 months and 11 at 6 months. Using cutoff at 30 dB HL (air-conduction), 2-month success rate was 5 of 17 patients (PTA: 0.5-1-2-4 kHz), 7 of 17 (PTA: 0.5-1-2-3 kHz), 9 of 17 (PTA: 0.5-1-2 kHz) and 15 of 17 (SRT: Speech recognition threshold). At 6 months, success rate was 6 of 11 patients (PTA: 0.5-1-2 kHz), 7 of 11 (PTA: 0.5- 1-2-3 kHz), 8 of 11 (PTA: 0.5-1-2 kHz) and 10 of 11 (SRT). When evaluating 6-month outcome by air-conduction measures, the highest success rates (91%) after stapes surgery were seen using SRT, and lowest (55%) using the 4-frequency average PTA: 0.5-1-2-4 kHz.
