This paper reports a case of type 1 posterior glottic stenosis in a 60-yearold woman that was misdiagnosed as bronchial asthma. The patient was intubated at another hospital after ingesting herbicide and extubated seven days later. Although her voice changed, she had not received treatment at that time. She visited a local internal medicine clinic when her condition deteriorated to the point of dyspnea, but several months of treatment for bronchial asthma failed to improve her symptoms. Upon admission to the author’s hospital, a laryngoscopic examination revealed a type 1 posterior glottic stenosis, which was removed surgically using a CO2 laser.
