喉手术不允许损伤环状软骨支架,因如部分软骨被切除,则将引致喉狭窄或/和误吸。因此环状软骨部分切除后应重新设计后部的垂直高度,以维持管腔的直径,从而可保证发声和呼吸功能。作者们提出一个新的概念,即“环状软骨塌陷(cricoid collapae)”,对于行水平部分喉切除和杓状软骨切除的一些病人,主张用重建术使声门闭合。杓状软骨重建失败多见于初次手术,其结果是声门闭合不全。在这些失败的病例中,用软骨移植重建较合宜。因此,环状软骨塌陷法 Thoracic surgery does not allow damage to the cricoid cartilage, as some of the cartilage is resected, which can lead to stenosis and / or aspiration of the larynx. Therefore, after resection of the annular cartilage should be re-design of the vertical height of the rear to maintain the diameter of the lumen, which can guarantee vocal and respiratory function. The authors propose a new concept, the “cricoid collapae,” which advocates reconstruction of the glottis for some patients undergoing partial laryngectomy and arytenoid cartilage resection. Cranial cartilage reconstruction failure more common in the first surgery, the result is the glottis insufficiency. In these failed cases, cartilage reconstruction is more appropriate. Therefore, the annular cartilage collapse method
