[Tracheobronchoplasty for Severe Diffuse Tracheomalacia]

Area of Science:

• Thoracic Surgery
• Respiratory Medicine
• Biomaterials Engineering

Background:

• Diffuse airway instability, including tracheobronchomalacia and excessive dynamic airway collapse, causes severe symptoms like dyspnea and intractable cough.
• Current treatments like silicone stents offer temporary symptom relief but are limited by complications, precluding long-term use.

Purpose of the Study:

• To evaluate the efficacy of surgical intervention using polypropylene mesh for definitive airway stabilization.
• To establish surgical mesh splinting as a permanent treatment option for severe tracheobronchomalacia and excessive dynamic airway collapse.

Main Methods:

• Posterior splinting of the Paries membranaceus using a polypropylene mesh to stabilize the trachea and main bronchi.
• Surgical intervention aimed at definitive stabilization for patients with documented severe airway instability.

Main Results:

• Surgical mesh splinting provides definitive stabilization of the trachea and main bronchi.
• This surgical approach is the only therapy capable of achieving permanent symptom control for severe tracheobronchomalacia and dynamic airway collapse.

Conclusions:

• Surgical mesh splinting is an appropriate and effective treatment for severe tracheobronchomalacia and excessive dynamic airway collapse.
• Permanent symptom control is achievable through this surgical method, though success is multifactorial and requires interdisciplinary collaboration.
