In order to investigate the pathological differences and similarities of vocal nodes and vocal polyps.
144 samples of vocal nodes and vocal polyps were examined by an experienced pathologist.
There were no significant statistical difference in short-term vocal nodes and vocal polyps. In long-term vocal nodes and vocal polyps, vocal nodes had thickened basal membrane, and abnormal keratinization of epithelium, vocal polyps had thin or discrete thickening of basement membrane, more pronounced edema, dilated vessels or growth of new blood vessels.
It proved that vocal nodes and polyps are the result of "microtraumas" occurring at various phases of wound repair, thus accounting for the homogeneity and heterogeneity of histological and clinical manifestations.
为了研究声带小结和声带息肉的病理异同。
由一位经验丰富的病理学家对144例声带小结和声带息肉样本进行检查。
短期的声带小结和声带息肉在统计学上无显著差异。长期的声带小结和声带息肉中，声带小结有基底膜增厚和上皮异常角化，声带息肉有基底膜变薄或局灶性增厚、更明显的水肿、血管扩张或新生血管生长。
证明声带小结和息肉是伤口修复各阶段发生的“微创伤”的结果，从而解释了组织学和临床表现的同质性和异质性。
