Treatment of tracheomalacia: eight years' experience
Insights
Aortopexy effectively treats tracheomalacia, relieving airway obstruction in most patients. However, current treatments for tracheobronchomalacia remain insufficient, indicating a need for further research and development.
Area of Science:
- Pediatric Surgery
- Thoracic Surgery
- Respiratory Medicine
Background:
- Tracheomalacia and tracheobronchomalacia are conditions characterized by weakness of the airway walls, leading to collapse and obstruction.
- These conditions often present in infants and can cause significant respiratory distress, recurrent infections, and difficulties with ventilation.
- Surgical intervention is sometimes necessary when conservative management fails.
Purpose of the Study:
- To evaluate the efficacy of aortopexy and external airway splinting in treating tracheomalacia and tracheobronchomalacia.
- To compare treatment outcomes between patients with tracheomalacia and those with tracheobronchomalacia.
- To assess the role of associated conditions, such as esophageal atresia, in treatment planning.
Main Methods:
- Retrospective review of 25 patients treated between 1978 and 1985 for tracheomalacia (n=21) or tracheobronchomalacia (n=4).
- Surgical interventions included aortopexy and/or external airway splinting.
- Patient data analyzed included age, indications for surgery, associated conditions, and treatment outcomes.
Main Results:
- Aortopexy successfully relieved airway obstruction in all 21 patients with tracheomalacia, with 3 requiring additional airway splinting.
- In patients with tracheobronchomalacia, aortopexy and splinting failed in 3 out of 4 cases, highlighting treatment challenges.
- The median age at treatment was 7 months, with common indications including "dying spells" and recurrent pneumonia.
Conclusions:
- Aortopexy is an effective primary treatment for tracheomalacia, with external airway splinting as a potential adjunct.
- Current surgical strategies are inadequate for treating tracheobronchomalacia, necessitating the development of novel therapeutic approaches.
- Further research is crucial to devise effective treatments for tracheobronchomalacia.
Abstract:
Between 1978 and 1985, 21 patients were treated for tracheomalacia, (group I) and 4 for tracheobronchomalacia (group II). The median age at treatment was 7 months (range 1 to 96 months). Indications for surgery in group I were, "dying spells" (n = 12), recurrent pneumonia (n = 4), intermittent respiratory obstruction (n = 3) and inability to extubate airway (n = 2). 18 had esophageal atresia repair. Treatment in group I was aortopexy (n = 19), three of whom also required an external airway splint; two had an airway splint only. Airway obstruction was relieved in all. Group II patients required surgery because they could not be extubated; none had esophageal atresia. Aortopexy in all and splinting in one failed in 3 of 4 patients. Aortopexy is the primary treatment of tracheomalacia. External airway splinting may be used where aortopexy is inadequate. A satisfactory treatment for tracheobronchomalacia has not yet been devised.
