The results of ossiculoplasty are frequently reported in terms of closure of the air-bone gap. This parameter is a reliable indicator of the degree of technical success, and is useful in comparing different materials and types of reconstructions. However assessment of the operated ear alone does not evaluate the effect of surgery on binaural hearing ability, leading to the situation where sub-optimal advice may be given to patients pre-operatively. This article advocates a more patient orientated method of assessing the results of ossiculoplasty. Previous studies have indicated that the operated ear must reach an air conduction level of 30dB for the speech frequencies or be within 15dB of the other ear to ensure that the patient will gain significant benefit. A graphical method for the prediction of patient benefit is presented, and compared to the rule of thumb quoted above. The implications for surgeons and patients considering ossiculoplasty are obvious.
鼓室成形术的结果通常根据气骨导差的闭合情况来报告。该参数是技术成功程度的可靠指标，有助于比较不同材料和重建类型。然而，仅对手术耳进行评估并不能评估手术对双耳听力能力的影响，这就导致在术前可能会给患者提供不太理想的建议。本文提倡一种更以患者为导向的评估鼓室成形术结果的方法。先前的研究表明，手术耳的言语频率气导水平必须达到30dB，或与对侧耳相差不超过15dB，以确保患者能获得显著益处。本文提出了一种预测患者获益的图表方法，并与上述经验法则进行了比较。这对考虑进行鼓室成形术的外科医生和患者的意义显而易见。
