Three infants aged 8, 9 and 10 months, have undergone a surgical repair of bronchomalacia employing an external stent to reconstruct the bronchial lumen. The preoperative state of these patients was non-specific persisting respiratory distress. Bronchoscopy and bronchography were diagnostic and demonstrated the collapse of the bronchial lumen. The involved bronchus was left in two and bilateral in one patient. At operation, the whole cirumference of the involved bronchus was exposed and taped. An elastic silastic sheet lined with Marlex mesh inside was placed around the bronchus for the three quaters of the circumference, and was sutured to the bronchial cartilage at both edges and mid portion of the silastic sheet. The triangular radiating tension, created by elasticity of the silastic sheet, provided a patent lumen in the collapsed bronchial segment. By this procedure, respiratory distress has improved to allow the endotracheal tube to be removed shortly after operation. During the followup period of 4-12 months, a sudden death at home, the cause of which is unknown, was seen in one patient. The other two patients have been free of disease.
