自1954年阿姆斯特朗发明耳环以来，人们一直用它来治疗中耳积液。然而，现在已被接受的是，鼓膜中存在的缝隙与鼓膜中鼓膜硬化的发展有关。此外，研究表明，这是一个渐进的现象，在植入假体后3至4年，发病率随着时间的推移而增加，高达65% （Mawson和Fagan, 1972； Tos和Poulsen， 1976）。最初有人认为鼓膜硬化可能是由中耳疾病引起的，而不是由耳套引起的（McKinnon, 1971）。然而，最近的研究发现，在双侧积液病例中，有耳套的鼓膜硬化发生的频率高于没有耳套的鼓膜硬化（Brown， Richards和Ambegaokar, 1978; Lildholt, 1979）。本前瞻性研究旨在揭示双侧中耳积液患儿鼓膜硬化的发展情况，并从临床病史和手术技术中找出可能与并发症发病机制相关的因素。
Grommets have been used as a treatment for middle-ear effusions since their introduction by Armstrong in 1954. However, it is now accepted that the presence of a grommet in a tympanic membrane is associated with the development of tympanosclerosis in that membrane. Furthermore, it has been shown that this is a progressive phenomenon and that the incidence increases with time to as much as 65 per cent at 3 to 4 years after grommet insertion (Mawson and Fagan, 1972; Tos and Poulsen, 1976). Initially it was suggested that the development of tympanosclerosis might be due to the middle ear disease rather than to the grommet (McKinnon, 1971). However, most recent studies hjave found that, in bilateral cases of effusion, tympanosclerosis develops more frequently in ears with a grommet than in those without (Brown, Richards and Ambegaokar, 1978; Lildholt, 1979).This prospective study was designed to show the development of tympanosclerosis in the tympanic membrane of children treated for bilateral middle-ear effusions and to elicit any factors from the clinical history and operative technique which might be associated with the pathogenesis of the complication.
