The advantages and disadvantages with cricothyroidotomy have been discussed by several authors during the last 12 years. The frequency of complications differs considerably probably depending on indications for surgery and methods of follow-up. In our own human material (253 patients cricothyroidotomized and 79 of 102 alive after 6 months followed up) there has been no case of laryngeal or tracheal stenosis. The aim of this study was to analyse the effect of the inflammatory granulation tissue on the surrounding tissues in 8 cricothyroidotomized pigs, and to analyse the regeneration of the mucosa and the healing with special regard to development of stenosis. Despite pronounced stomal infection and formation of granulation tissue we found no case of stenosis, no injuries of the cartilage and a complete regeneration of the ciliated epithelium.
在过去12年里，几位作者讨论了环甲膜切开术的优缺点。并发症的发生率差异很大，这可能取决于手术指征和随访方法。在我们自己的人体研究资料中（253例行环甲膜切开术的患者，6个月后102例存活患者中有79例接受了随访），没有出现喉或气管狭窄的病例。本研究的目的是分析8只接受环甲膜切开术的猪的炎性肉芽组织对周围组织的影响，并特别针对狭窄的发展情况分析黏膜的再生和愈合情况。尽管存在明显的造口感染和肉芽组织形成，但我们未发现狭窄病例、软骨损伤以及纤毛上皮的完全再生。
