Methods: Nine patients with severe hypopharyngeal stricture after total laryngectomy were treated with endovascular stent implantation, and the effect of endoluminal stent treatment was observed. Results: 8 cases were placed successfully, dysphagia obviously improved, 1 case failed to place. All cases were followed up for 5 ~ 36 months, all patients had significantly improved eating status compared with that before operation, and 3 cases died 3 ~ 8 months after operation. Conclusion: Choosing the appropriate endoluminal stent for interventional therapy can rapidly swallow the severe hypopharyngeal stricture after total laryngectomy, effectively relieving the difficulty of swallowing, is convenient to use, quick in effect and reliable in curative effect, and can be used as one of the methods to relieve stenosis
