A prospective study was undertaken in 72 children comparing a new type of tympanostomy tube, the Lens tube, in one ear, and a Donaldson tube in the contra-lateral ear as a control. The average survival times of the tubes differed significantly: 17.20 months for the Lens tube, and 11.31 months for the Donaldson tube (P < 0.001). By contrast, the relapse rate (22% with the Lens tube vs 21% with the Donaldson tube) after extrusion or extraction, and the residual perforation rate (3% with the Lens tube vs 6% with the Donaldson tube) were not significantly different. Otorrhea was not significantly different either: 25% with the Lens tube vs 16% with the Donaldson tube.
对72名儿童进行了一项前瞻性研究，比较一种新型鼓膜造孔管（Lens管）在一只耳朵中的情况，以及对侧耳朵中作为对照的唐纳森管。两种管子的平均留存时间有显著差异：Lens管为17.20个月，唐纳森管为11.31个月（P < 0.001）。相比之下，脱出或取出后的复发率（Lens管为22%，唐纳森管为21%）和残余穿孔率（Lens管为3%，唐纳森管为6%）没有显著差异。耳漏情况也没有显著差异：Lens管为25%，唐纳森管为16%。
