Sequential scintigraphy enables the qualitative and quantitative study of the drainage function of the Eustachian tube. Use is made of serum albumin labeled with technetium 99 m. After reviewing the various methods employed in an exploration of the functions of the Eustachian tube, and in particular the drainage function, the writers explain the method in detail (indicator, detection system, examination procedure, normal scintigraphic aspects) while stressing the control factors (onset of passage, speed and intensity of passage, length of time for the appearance of a trace on the pharynx, eventual aspects of blocking) and giving the basic characteristics; persistant spotting of the drum, transient image of the tube, partial stoppage at the ostium, and traces along the pharynx. The role of swallowing and the position of the head appear to be essential. Results obtained in various disorders of the middle ear, accessory cavities, the tube and the cavum are given in the form of tables. The writers then indicate the principal merits of the method: demonstration of the pathological role of the Eustachian tube in a work-up of transmission deafness, with its impact on treatment, the role of a deficient drainage function in surgical failures, and control of the efficacy of treatment, in particular crenotherapy. A study of the drainage function of the Eustachian tube, as a complement to the function of equalizing pressure, in an essential factor in formulating indications and in establishing the prognosis for tympanoplasties.
序贯闪烁扫描术可对咽鼓管的引流功能进行定性和定量研究。使用的是用锝99m标记的血清白蛋白。在回顾了探索咽鼓管功能，特别是引流功能所采用的各种方法后，作者详细解释了该方法（指示剂、检测系统、检查程序、正常闪烁扫描影像），同时强调了控制因素（通过的起始、通过的速度和强度、咽部出现痕迹的时间长度、阻塞的最终表现）并给出了基本特征：鼓膜持续有斑点、咽鼓管的短暂影像、开口处部分阻塞以及沿咽部的痕迹。吞咽的作用和头部的位置似乎至关重要。以表格形式给出了在中耳、副鼻窦、咽鼓管和腔的各种疾病中获得的结果。作者随后指出了该方法的主要优点：在传导性耳聋的检查中证明咽鼓管的病理作用及其对治疗的影响、引流功能不足在手术失败中的作用以及对治疗效果的控制，特别是冷冻疗法。作为压力平衡功能的补充，对咽鼓管引流功能的研究是制定鼓膜成形术适应症和确定预后的重要因素。
