ABSTRACT
OBJECTIVE:
Tracheobronchomalacia is one of the common respiratory tract dysplasia in children. Its symptoms are nonspecific, and routine methods are unreliable in the assessment of tracheobronchomalacia in children. In addition, many physicians are confused about its clinical characteristics, so tracheobronchomalacia is often underdiagnosed. The purpose of this study was to explore the clinical features of tracheobronchomalacia in children and to investigate the diagnostic value of flexible bronchoscopy for children with tracheobronchomalacia.METHOD:
For diagnosis and treatment, 229 children out of 4725 patients hospitalized in the division of respiratory disorders were examined by Olympus BF3c-20 flexible bronchoscopy or by Olympus BF-P20 flexible bronchoscopy under general anesthesia with propofol, in Chongqing Children's Hosptial from April 2004 to April 2006. Fifty-three cases were confirmed to have tracheobronchomalacia by bronchoscopy, patients' data including airway lesion, age, sex, clinical characteristics, aided examinations, treatment, final outcomes, were collected and analyzed.RESULTS:
(1) Of the 53 children with tracheobronchomalacia, 31 were not suspected for this diagnosis prior to bronchoscopy, who were instead misdiagnosed as refractory pneumonia, difficult-to-control asthma, bronchial foreign body, bronchopulmonary dysplasia and pulmonary atelectasis of unknown origin or bronchiolitis. (2) In the 53 children with tracheobronchomalacia aged one month to eight years, 41 were infants, 6 were younger than two years, 4 were younger than 3 years and the rest 2 cases were older than 3 years. The risk of tracheobronchomalacia related inversely with ages. Ten cases were girls and 43 were boys. (3) Eleven cases had tracheomalacia, 24 bronchomalacia, 18 tracheobronchomalacia; 12 cases had malacia on left lung, 11 on right lung, 19 on both sides; 21 children were mild cases, 25 moderate cases, 7 severe cases. (4) In the 53 children with tracheobronchomalacia, 28 had recurrent or prolonged wheezing, 16 chronic cough, 5 recurrent respiratory infections, 2 atelectasis of unknown origin, and 2 dyspnea.CONCLUSIONS:
The infants and toddlers seem to be predisposed more to the bronchomalacia than the older children. Clinical features of children with airway malacia were variable and atypical, expiratory stridor and cough are the most commonly reported symptoms. Flexible bronchoscopy should be regarded as a "golden standard" method for diagnosing TBM.
