Conclusion: Delivery of a carbon dioxide laser is an effective method and can be used in selected cases of tracheal stenosis.
Objectives: To present retrospective experience in tracheal stenosis of 16 patients treated by bronchoscopic delivery of carbon dioxide laser, considering the characteristics of the treated stenosis, surgical procedures performed, and post-operative outcomes and complications.
Methods: All demographic and clinical data were collected retrospectively. Chest and neck computed tomography scans were performed to assess the stenosis, including length, location, and glottic involvement. The stenotic area was evaluated endoscopically according to an adapted Meyer and Cotton grading scale.
Results: The aetiology of the tracheal stenosis was intubation-related in 14 cases, and idiopathic in two cases. The duration of intubation ranged between 1 hour to 26 days. According to the Myers-Cotton classification, mean stage of stenosis for the study group was 3.3 ± 0.5. Mean length of the stenosis was 23.75 ± 6.95 (range = 15-40) mm. Mean follow-up for the study group was 23.81 ± 7.11 (range = 12-38) months. Postoperative decannulation was achieved in 13 patients (81.3%), and decannulation was not achieved in three patients (18.7%).

Introduction: Repairing damaged cartilage poses significant challenges, particularly in cases of congenital cartilage defects such as microtia or congenital tracheal stenosis, or as a consequence of traumatic injury, as the regenerative potential of cartilage is inherently limited. Stem cell therapy and tissue engineering offer promising approaches to overcome these limitations in cartilage healing. However, the challenge lies in the size of cartilage-containing organs, which necessitates a large quantity of cells to fill the damaged areas.

Mediastinal mass syndrome represents a major threat to respiratory and cardiovascular integrity, with difficult evidence-based risk stratification for interdisciplinary management. We conducted a narrative review concerning risk stratification and difficult airway management of patients presenting with a large mediastinal mass. This is supplemented by a case report illustrating our individual approach for a patient presenting with a subtotal tracheal stenosis due to a large cyst of the thyroid gland.

Pulmonary involvement is commonly observed in anti-neutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV), presenting with manifestations such as diffuse alveolar hemorrhage, inflammatory infiltrates, pulmonary nodules, and tracheobronchial disease. We aimed to identify distinct subgroups of tracheobronchial disease patterns in patients with anti-neutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV) using latent class analysis (LCA), and to evaluate their clinical characteristics and outcomes. We conducted a retrospective cohort study using electronic medical records of patients aged >18 years diagnosed with AAV and tracheobronchial disease between 1 January 2002 and 6 September 2022.

The patient was a 66-year-old man who developed exacerbation of respiratory and heart failure that necessitated tracheal intubation. The exacerbation was considered to be largely caused by asthma-chronic obstructive pulmonary disease overlap syndrome and type 3 pulmonary hypertension. However, left diaphragmatic eventration and tracheal stenosis were also found.
