广泛采用 又怎么 使用受到限制？

One of the first classification tools which allowed for a more uniform approach to airway stenosis was developed in 1994 by Myer and Cotton, known as the Myer- Cotton airway grading system. The grading system classifies the degree of subglottic stenosis into four grades: Grade I (<50% luminal obstruction), Grade II (51–70%), Grade III (71–99%), and Grade IV (100%) [26]. Although it was widely adopted in clinical practice, its use was limited as it described only the subglottic region and did not account for the extent, conformation, and dynamic nature of the stenosis.

Myer和Cotton于1994年开发了第一种允许气道狭窄更统一分类的工具，称为Myer-Cotton气道分级系统。该分级系统将声门下狭窄程度分为4级：I级（<50%管腔阻塞）、II级(51-70%)、III级(71-99%)和IV级(100%)[26]。尽管在临床实践中被广泛采用，但由于其仅描述了声门下区域，未考虑狭窄的范围、形态和动态性质，因此使用受到限制。

如果作用有限倒是可以的？
