How I do it: novel use of a modified nasopharyngeal airway in laryngotracheal stenosis as a temporary stent

Abstract

Abstract Background This paper reports the innovative use of a modified nasopharyngeal airway device as a temporary stent in patients with laryngotracheal stenosis. It also discusses the technique of endoscopic stent placement, and our experience in terms of the indications and suitability. Method The nasopharyngeal airway device was modified to use as an airway stent by trimming it to the desired length. Next, the stent was inserted endoscopically and anchored using a novel approach. Results The surgery was performed successfully without complications. The patients had full use of their voice while the stent was in situ. No significant granulation tissue was observed. Conclusion This paper demonstrates the feasibility of using a nasopharyngeal airway device as a temporary stent to prevent restenosis in cases where the patients have a strong demand for phonation. The modified nasopharyngeal airway device is potentially very promising, but cases must be selected carefully to avoid compromising efficacy and safety.
