The advent of tracheobronchial stent has allowed physicians to improve airway obstruction of both benign and malignant obstruction. Benign stenosis of the trachea and bronchi related to intubation, inflammation and granulomatous disease has been treated successfully with stenting. Other benign processes such as tracheomalacia and post-lung transplantation anastomotic stenosis have also been alleviated with stent placement. But the most common use for these stent is for the relief of malignant obstructive-lesion. Although stent placement is not a curative procedure, it can improve airway patency substantially, thus relieving dypnea and potentially improving quality of life. Recently, we placed a tracheal stent to relieve patient’s dyspnea caused by recurrent thyroid cancer. So, we would like to introduce our experience with a case of malignant tracheal stricture caused by recurrent thyroid papillary carcinoma. We could restore airway patency in this patient by placement of a metallic endotracheal stent. (Korean J Otolaryngol 2003;46:794-7)
