The lamina propria of the tympanic membrane is composed of a unique system of radial and nonradial fibers which contribute importantly to its function. Over 1000 patients have undergone operations for the transplantation of the homograft tympanic membrane. Animal experiments have been presented to determine whether or not the fiber system of the lamina propria of the tympanic membrane is preserved in the homograft tympanic membrane. In conjunction with this, a small series of experiments was conducted to determine the appearance of the fiber system in perforations that heal spontaneously. Current knowledge concerning the function of the fiber network is discussed. The results of the present study indicate that the lamina propria fiber network is at least partially preserved in the homograft tympanic membrane and that the fiber network of the lamina propria is not reconstituted in spontaneously healed tympanic membranes.
鼓膜的固有层由独特的放射状和非放射状纤维系统组成，这对其功能起着重要作用。已有1000多名患者接受了同种异体鼓膜移植手术。已经进行了动物实验，以确定同种异体鼓膜中鼓膜固有层的纤维系统是否得以保留。与此同时，还进行了一小系列实验，以确定自发愈合穿孔中纤维系统的外观。本文讨论了有关纤维网络功能的现有知识。本研究结果表明，同种异体鼓膜中固有层纤维网络至少部分得以保留，且自发愈合的鼓膜中固有层纤维网络不会重新形成。
