気管切開孔より内視鏡下に摘出した挿管性声門下肉芽腫症例

We experienced a case of a subglottic intubation granuloma. A 75-year-old woman had been intubated for 8 days for treatment of acute myocardial infarction. The process was uneventful and she was discharged. However, about four months later, she had a severe attack of dyspnea and she was transported to the emergency department of our hospital. An endoscopic examination revealed a subglottic mass which occupied almost the whole subglottic space.Immediately intubation was performed, and subsequently we performed a tracheotomy. Microlaryngeal surgery or laryngofissure are popular for the surgical approach to subglottic tumors, but we performed endoscopic surgery via the tracheostoma using forceps and endoscopes usually used for sinus surgery. We resected a 2 cm subglottic tumor the histological assessment of which was a granuloma. We think that endoscopic surgery via a tracheostoma is very useful for subglottic and proximal tracheal lesions. We hope the technique will be applied for a variety of indications and will develop in the foreseeable future.
