Endolaryngeal stenting in patients with irregularly shaped larynges can be challenging. In such cases, the use of a moldable yet reasonably rigid endolaryngeal stent is desirable. The purpose of this report is to describe our experience with silicone hearing aid material as a moldable endolaryngeal stent in a patient with an atypically shaped larynx.
A patient with relapsing polychondritis that resulted in complete stenosis of the subglottic airway underwent laryngotracheal reconstruction. Moldable silicone, commonly used to prepare ear canal molds for hearing aids, was molded into the neo-endolarynx to serve as a custom-made endolaryngeal stent.
The patient tolerated the moldable silicone stent well and had a patent airway with epithelialization 8 months after removal.
Silicone mold material is a suitable substance for endolaryngeal stenting. It conforms to the configuration of the individual's airway, is tolerated well, can be removed relatively easily, and is a useful alternative to prefabricated stents in laryngotracheal reconstruction.
对于喉部形状不规则的患者，进行喉内支架置入术可能具有挑战性。在这种情况下，需要使用可塑形但又具有一定刚性的喉内支架。本报告的目的是描述我们使用硅胶助听器材料作为可塑形喉内支架，应用于一名喉部形状异常患者的经验。
一名患有复发性多软骨炎导致声门下气道完全狭窄的患者接受了喉气管重建术。将通常用于制作助听器耳道模具的可塑形硅胶，塑形成新喉，用作定制的喉内支架。
患者对可塑形硅胶支架耐受良好，取出支架8个月后气道通畅且上皮化。
硅胶模具材料是喉内支架置入的合适材料。它能贴合个体气道的形态，耐受性良好，相对容易取出，并且是喉气管重建中预制支架的一种有用替代物。
