Abstract：
OBJECTIVE: To assess the effectiveness of a new suturing technique called Dragonfly for the closure of temporary tracheotomies. This technique involves placing two sutures during the tracheotomy procedure and leaving them loose and unknotted until the day of skin closure.
METHODS: Retrospective case control study. Monocentric study at a department of Otolaryngology and head and neck surgery at a tertiary centre in Italy. A total of 50 patients who underwent temporary tracheotomy between January 2017 and December 2021. Patients were divided into two groups based on the trachea closure method: traditional closure with sutures placed during the skin closure procedure (Group A) and the Dragonfly technique (Group B). The incidence of tracheal stenosis by Computed Tomography (CT), granulation tissue formation, bleeding, procedure duration, patient discomfort were evaluated.
RESULTS: The incidence of tracheal complications and tracheal stenosis was reduced in Group B (6%) compared to Group A (24%). Procedure times (3 min vs. 6 min) durations was significantly shorter. No patients had symptoms of tracheal stenosis at the end of the procedures.
CONCLUSIONS: The Dragonfly suturing technique is effective and safe for tracheotomy closure, reducing the incidence of tracheal stenosis and shortening hospitalization duration compared to the traditional method.

摘要：
目的：评估一种名为Dragonfly的新缝合技术用于闭合临时气管切开术的有效性。该技术涉及在气管切开术过程中放置两条缝线，并使它们松弛且未打结，直到皮肤闭合之日。
方法：回顾性病例对照研究。意大利三级中心的耳鼻咽喉科和头颈外科的单中心研究。共有50名患者在2017年1月至2021年12月期间接受了临时气管切开术。根据气管闭合方法将患者分为两组：在皮肤闭合过程中放置缝线的传统闭合（A组）和Dragonfly技术（B组）。通过计算机断层扫描（CT）检查气管狭窄的发生率，肉芽组织形成，出血,程序持续时间,对患者的不适感进行了评估。
结果：与A组（24％）相比，B组（6％）的气管并发症和气管狭窄的发生率降低。手术时间(3分钟vs.6分钟）的持续时间明显较短。手术结束时，没有患者出现气管狭窄的症状。
结论：Dragonfly缝合技术对于气管切开闭合是有效和安全的，与传统方法相比，降低了气管狭窄的发生率，缩短了住院时间。
