Due to the simplicity of their manufacture and placement, middle-ear prostheses are generally constructed using only a single 'ossicle'. The variety of pathologies frequently make it necessary to devise individual solutions and the results are often unsatisfactory. Many methods of improving the prostheses have been tried, with very mixed results. Even until recently, the fundamental assumptions underlying the use of single-ossicle, or columellar, prosthesis have been questioned, with suggestions that this type of prosthesis should be abandoned in favour of attempts to reconstruct a true three-ossicle middle ear. As some of the assumptions in the literature regarding columellar middle ears are incorrect and some published information is not easily accessible, a brief review of pertinent details of non-mammalian systems is given here.
由于中耳假体的制造和植入较为简单，通常仅使用单个“听小骨”来构建。多种病理情况常常使得有必要设计个性化的解决方案，但结果往往不尽人意。人们尝试了许多改进假体的方法，结果好坏参半。甚至直到最近，使用单听小骨或柱状假体的基本假设也受到了质疑，有人建议应放弃这种类型的假体，转而尝试重建真正的三听小骨中耳。鉴于文献中关于柱状中耳的一些假设不正确，且一些已发表的信息不易获取，在此对非哺乳动物系统的相关细节进行简要综述。
