Abstract

We reported on a case of intratracheal granulation after the closure of a tracheostoma. A 69-year-old man underwent neck debridement and a tracheostomy to treat a deep neck infection. During the tracheostomy, the isthmus of the thyroid gland was resected and ligatured for both resected ends. After the deep neck infection improved, the tracheostoma was closed. Two months later, he complained of pharyngolaryngeal discomfort and of dyspnea. An intratracheal nodule was observed between the subglottic and the tracheal sections by flexible endoscopy. Two ligatures of silk thread were seen at the tip of the tumor. Computed tomography showed an intratracheal tumor with a different density from the thyroid gland. He underwent a tracheostomy again and the nodule was resected stimultaneously. The nodule was pathologically diagnosed as inflammatory granulation, which was not observed in the specimen of thyroid gland tissue. There has been no recurrent intratracheal granulation for twelve months since the operation.
 It was suggested that the granulation in this case was caused by the ligature thread. It is necessary to observe the space from the subglottic to the tracheal regions when the patient complains respiratory symptoms after the closure of a tracheostoma.
