通常报告中耳手术的效果是依据术后气骨导差的缩短和术后气导的改善,而这些都和评价操作技术的成功及单耳听力减少程度有关,并不需要考虑病人是否受益。这个由许多因素决定的问题,至少包括非手术耳的听力情况。作者提出一种新的估价中耳手术效果的方法。首先是绘图,纵轴表示手术耳的气导平均阈值(dBHL),横轴表示非手术耳的气导平均阈值
The effectiveness of the middle ear surgery is usually reported on the basis of the shorter postoperative airway densitometry and postoperative air conduction improvement, all of which are related to the success of operating techniques and the reduction in monaural hearing, without regard to whether the patient benefits. This problem, which is determined by many factors, at least includes the hearing of non-surgical ears. The authors propose a new method of evaluating the effect of middle ear surgery. The first is plotting, the vertical axis represents the mean airway conductance threshold (dBHL) for the surgical ear and the horizontal axis represents the mean airway conductance threshold for the non-surgical ear
