声带息肉和小结是上皮下组织的增生,所以分为息肉和小结是基于临床表现。声带息肉和小结的结构依赖于它们的病变大小、血管形成、血肿和其它退行性变化,没有喉科检查单从组织病理学来区分息肉和小结或许是不可能的。声带小结是双侧声带前三分之一和中三分之一交界处边缘上的对称性结节。声带息肉的大小不同,一般比声带小结大些。也是常常出现在声带的自由缘。它们通常呈灰白色,并且光滑,最近有人主张声带小结和息肉是同一病变过程的不 Vocal cord polyps and the summary of subcutaneous tissue hyperplasia, so divided into polyps and summary is based on clinical manifestations. The structure of vocal cord polyps and nodules depends on their size, angiogenesis, hematoma, and other degenerative changes. Without a throat checklist it may not be possible to differentiate between polyps and nodules from histopathology. Vocal nodules are symmetrical nodules on the edges of the first third and the middle third of the bilateral vocal cords. Vocal cord polyps of different sizes, generally larger than the vocal nodules.
