Tympanostomy tube treatment was used in 181 patients on 323 ears and a followup study was made as an average three years and two months later. Sixty-five percent of the ears had healed completely and in these the average tube treatment time had been 11.3 months. In 22% the tubes were still in position, the average time for treatment being 24.2 months. Five percent showed purulent discharge and recurrence of the glue ear was noted in 3%. A dry perforation developed in five patients. Cholesteatoma was seen in four ears but in only one of these it may have been related to the location of the tube at the posterior drum margin.
对181例患者的323只耳朵进行了鼓膜置管治疗，并在平均三年零两个月后进行了随访研究。65%的耳朵已完全愈合，这些耳朵的平均置管治疗时间为11.3个月。22%的耳朵中置管仍在位，平均治疗时间为24.2个月。5%的耳朵有脓性分泌物，3%的耳朵出现胶耳复发。5例患者出现干性穿孔。在4只耳朵中发现了胆脂瘤，但其中只有1只可能与鼓膜后缘置管的位置有关。
