In young rabbits (4-week-old) the growth of the subglottis was studied after an endolaryngeal soft tissue trauma. The injury induced the formation of a subglottic stenosis. In contrast to earlier observations on endolaryngeal trauma extending into the cricoid cartilage, the cricoid developed normally to the adult size and shape at 24 weeks. Similar to the earlier findings, the subepithelial layer showed considerable thickening as the result of formation of scar tissue, ectopic cartilage and fatty tissue with interruption of the elastic tunica (= conus elasticus). It was concluded that after endolaryngeal trauma in rabbits two types of subglottic stenosis can develop, determined by the depth of the injury.
在幼兔（4周龄）中，研究了喉内软组织创伤后声门下的生长情况。该损伤导致了声门下狭窄的形成。与先前关于延伸至环状软骨的喉内创伤的观察结果不同，环状软骨在24周时正常发育至成年大小和形状。与早期研究结果相似，上皮下层由于瘢痕组织、异位软骨和脂肪组织的形成以及弹性膜（=弹性圆锥）的中断而显著增厚。得出的结论是，兔喉内创伤后可形成两种类型的声门下狭窄，这取决于损伤的深度。
