One hundred and eighty-four cases of vocal polyps and 64 cases of vocal nodules are reported. Of these cases, 6 polyps and 10 nodules had been studied with electron microscope: 40 cases of polyps and 15 cases of nodules were investigated histo-chemically with PAS, AB-PAS, HID-AB, Congo Red and other methods. It seems that polyps are distinctly different from nodules. They are different diseases. The main difference between them is that polyp of the vocal cord is caused primarily by circulation impediment, thrombosis, exudation and edema of the lamina propria of the mucous membrane due to inflammation, there is secondary atrophy of the epithelium of the cord, vocal nodule is caused primarily by vocal abuse, this leads to friction or dash of the vocal cords against each other, there is circumscribed hyperplasia or hyperkeratinization and secondary hyaline-degeneration in lamina propria of the cord. The differential diagnosis, pathogenesis and treatment had been discussed.
报告了184例声带息肉和64例声带小结。其中，6例息肉和10例小结进行了电子显微镜研究；40例息肉和15例小结用PAS、AB - PAS、HID - AB、刚果红等方法进行了组织化学研究。似乎息肉与小结明显不同。它们是不同的疾病。它们之间的主要区别在于，声带息肉主要是由炎症引起的黏膜固有层血液循环障碍、血栓形成、渗出和水肿所致，声带上皮有继发性萎缩；声带小结主要是由用声过度引起的，这导致声带相互摩擦或碰撞，声带固有层有局限性增生或角化过度及继发性透明变性。文中对鉴别诊断、发病机制及治疗进行了讨论。
