title: [Operative indications for tracheobronchomalacia].
abstract: Tracheobronchomalacia in 3 children and 4 adults was reviewed, and operative indications were investigated. Tracheobronchomalacia in children differed from that in adults in that the lesion was localized and spontaneous healing was effected by cartilage growth and hardening. In adults, tracheobronchomalacia was characterized by a notch on the expiratory flow volume curve and higher V peak of inspiratory flow volume curve than that of expiratory curve. Operative indications for tracheobronchomalacia are BP higher than 28.2 cmH2O and delta CT higher than 15.4 cmH2O. Of 2 patients with tracheobronchomalacia in whom airway pressure was measured, one was a candidate for operation, and in the other, surgery was contraindicated because of low BP due to chronic obstructive pulmonary disease.
