Abstract

Three cases of airway stenosis caued by granulation were successfully treated by bronchoscopic intralesional injection of triamcinolone acetonide (TA). The first case was a 48-year-old man in whom bilateral vocal cord paralysis developed after thyroidectomy for thyroid cancer. Tracheostomy was done and a T-tube was inserted. After 1 year, T-tube removal was attempted but it was not possible due to the presence of subglottic stenosis caused by granulation. Bronchoscopic intralesional injection of TA was performed, which reduced the stenosis and allowed T-tube removal and stomal closure. The second case was an 80-year-old woman with tracheal stenosis due to granulation caused by intubation. Bronchoscopic laser irradiation alleviated the stenosis, but 1 month later granulation recurred at the stenotic site. After multiple intralesional injections of TA, the stenosis did not recur and the patient was discharged. The third case was a 70-year-old woman who had undergone sleeve segmentectomy of right S^2. She was found to have stenosis of the right upper lobe bronchus just proximal to the anastomosis due to granulation. The stenosis subsided after intralesional injection of TA. Intralesional injection of TA performed under bronchoscopy is technically feasible and is minimally invasive. So far, no apparent side effects or complications have been reported. It can be considered as an alternative to airway reconstruction or stenting in the treatment of airway stenosis caused by granulation.
