Treatment of tracheo(broncho)malacia in children

peer reviewedTracheomalacia (TM) is characterized by tracheal collapse due to an intrinsic anomaly resulting in a lack of rigidity of the cartilaginous rings and/or the posterior membrane during expiration, coughing or crying. It may also be secondary to external compression or acquired during endobronchial diseases. TM is commonly associated with other syndromes or airway abnormalities. Tracheomalacia can be localized or diffused and if the main bronchi are involved, the term of tracheobronchomalacia (TBM) is used. The most common symptoms include expiratory stridor, barking cough and recurrent respiratory tract infections. If tracheal weakness is severe, Acute Life Threating Events (ALTE) or Brief Resolved Unexplained Event (BRUE) can occur. While mild forms usually do not require any treatment, severe TBM may require medical and/or surgical management. Amongst several possible treatments, including tracheostomy, noninvasive ventilation and airway stenting, the pexy surgical approach (posterior, anterior tracheopexy or aortopexy) is currently the favoured option
