Abstract
Thirty-two patients with symptomatic tracheal deformity following ventilatory assistance through cuffed tracheal tubes have been treated during a seven-year period. The diagnosis is strongly suggested by symptoms of upper-airway obstruction following decannulation. Radiologic studies and bronchoscopy are invaluable diagnostic adjuncts. The lesions may consist of deformity of anterior wall or stenosis at the tracheostomy site, or more typically, of circumferential stenotic lesions at the level of the inflatable cuff. Tracheomalacia also occurs. The etiology appears primarily to be pressure necrosis caused by the rigidly inflated cuff, with subsequent cicatrization. Resection of the stenosis and primary reconstruction of the trachea is the definitive treatment of choice, as results are generally good. Dilatation and stenting are usually of temporary values only. In a small number of patients, permanent tracheostomy must be accepted.
