九二○又称赤霉素A_3,是一种植物激素,现已应用于临床治疗多种疾病,具有显著的扩张血管、促进血液循环和组织生长的作用。应用九二○修补鼓膜穿孔,可使穿孔边缘出现充血性红环,改善鼓膜血液循环,调动鼓膜生长的内在条件。但临床上常遇到生长困难的病例,往往是由于鼓膜外层的复层鳞状上皮向内生长超过了穿孔边缘,影响内层和中层纤维元的生长。为此,我们采用搔刮法使穿孔边缘造成人工出血,露出新鲜创面,除掉了妨碍鼓膜生长的因素,使九二○的作用得到充分发挥。1971～1979年,我科以此种方法修补各型鼓膜穿孔共98例,其中81例(81耳)全部闭合(占82.6%),15例穿
Ninety-two, also known as gibberellin A_3, is a plant hormone, has been used in clinical treatment of a variety of diseases, with significant dilation of blood vessels, promote blood circulation and tissue growth. The application of nine two ○ repair tympanic membrane perforation, perforation can make congested red ring edge, to improve tympanic membrane blood circulation, mobilization of the inherent conditions of tympanic membrane growth. However, often encountered in clinical growth of difficult cases, often due to the tympanostomy layer of squamous epithelium inward growth beyond the perforation edge, affecting the inner and middle fiber growth. To this end, we use scraping method to cause artificial perforation edge bleeding, exposing a fresh wound, remove the factors that hinder the growth of the tympanic membrane, so that the role of the 920 play. From 1971 to 1979, 98 cases of tympanic membrane perforation were repaired in this way by our department. Among them, 81 cases (81 ears) were closed (82.6%) and 15 cases were worn
