A comparison of the postoperative air-bone gaps to pre- and postoperative bone condition (BC) was made in two groups of patients with otosclerosis, 18 cases with poor preoperative BC thresholds and 15 cases with good preop, thresholds. The gaps to the postoperative BC showed less variation than the gaps to the preop. BC threshold, the postop. BC may therefore serve as a more stable and natural reference when calculating a postoperative air--bone gap.
对两组耳硬化症患者的术后气骨导差与术前及术后骨状况（BC）进行了比较，其中一组18例术前BC阈值较差，另一组15例术前阈值良好。与术后BC的差值相比，与术前BC阈值的差值变化较小。因此，在计算术后气骨导差时，术后BC可作为更稳定、更自然的参考值。
