The objective of our study was to document the feasibility of a novel endoscopic anterior cricoid split and rib grafting technique in a goat airway model.
Feasibility pilot animal study.
Animal surgical laboratory at a tertiary hospital and research center.
Three Ardhi goats were utilized. After harvesting and shaping the rib graft, 2 sutures were inserted transversely into the graft. An endoscopic midline anterior cricoid split was performed and extended down through the first tracheal ring, followed by a balloon dilation of the site. Next, the 2 lower and upper graft suture ends were sequentially passed as endo-extra laryngeal sutures and tied on the anterior neck skin. Laryngeal stent was utilized in 1 goat following graft placement.
The surgery was successful in all included animals and bronchoscopy performed 7 days after surgery, revealed that the anterior graft was in good position. One goat developed surgical site infection leading to partial graft resorption.
This study demonstrated the feasibility of this novel procedure which is potentially useful for patients who are candidates for a single-stage reconstruction. Future studies should investigate the safety and validity of this technique in a model with subglottic stenosis.

本研究的目的是在山羊气道模型中记录一种新型内镜下环状软骨前部劈开及肋骨移植技术的可行性。
可行性初步动物研究。
一家三级医院和研究中心的动物外科实验室。
使用3只阿尔迪山羊。在获取并塑形肋骨移植物后，将2根缝线横向插入移植物。进行内镜下环状软骨前部中线劈开，并向下延伸至第一气管环，随后对该部位进行球囊扩张。接下来，将移植物上下两端的缝线依次作为喉内外缝线穿过，并在前颈部皮肤打结。1只山羊在植入移植物后使用了喉支架。
所有纳入研究的动物手术均成功，术后7天进行的支气管镜检查显示前部移植物位置良好。1只山羊发生手术部位感染，导致部分移植物吸收。
本研究证明了这种新手术的可行性，该手术对适合一期重建的患者可能有用。未来的研究应在声门下狭窄模型中研究该技术的安全性和有效性。
