Introduction: In the last few decades the different bronchoscopic procedures have gained an important role in the treatment of airway stenosis, and the number of implanted airway stents has also greatly increased.
Patients: Between 1998 and 2004 the authors implanted altogether 108 airway prosthesis in 90 patients at the Institute of Pulmonology of Pest County. 58% of the patients were males, 42% females, the average age was 57.5 years, the average follow-up time was 7 months.
Results: On the basis of different etiology the patients were separated into two main groups. In 57% the airway stenosis was caused by malignant illnesses, in these cases stents can be used only with palliative purpose. However, in case of benign lesions they can offer a long-term solution and require an adequate follow-up of the patients. The authors' main aim was to get an overall picture of the interventions they had done by processing the data, with the help of the measurable characteristics that make possible to follow the airways' permeability and its changes. Analysing the results of the respiratory function and blood gas examinations they didn't find a significant difference inspite of the subjective improvement.

Airway stenosis (AS) is a fibroinflammatory disease characterized by abnormal activation of fibroblasts and excessive synthesis of extracellular matrix, which has puzzled many doctors despite its relatively low prevalence. Traditional treatment such as endoscopic surgery, open surgery, and adjuvant therapy have many disadvantages and are limited in the treatment of patients with recurrent AS. Therefore, it is urgent to reveal the pathogenesis of AS and accelerate its clinical transformation.

Background: Pulmonary epithelioid hemangioendothelioma (P-EHE) is a rare vascular tumor derived from mesenchymal cells with an incidence of about 1/1 million. The etiology remains unclear, and there are no established treatment guidelines. The tumor can occur in a variety of organs, among which the liver, lung and bone are the most commonly involved, with different clinical manifestations, mainly depending on the organ involved, but none of them is specific.

Management of difficult airways in the emergency department is challenging. Herein, we report a case of successful management of severe upper airway obstruction caused by angioedema, where intubation was achieved using a dual-function video laryngoscope and bronchoscope system in the emergency department for a patient with severe upper airway stenosis due to angioedema. A 74-year-old obese man with dyspnea presented to our emergency department.

Importance: Airway stenosis is a rare but debilitating disorder that significantly degrades the quality of life in affected patients. Treatments are primarily surgical, and disease management lacks established medical therapies. The North American Airway Collaborative held its third symposium at The Johns Hopkins Hospital in Baltimore, Maryland, on April 15, 2024, focused on strategies to advance the care of these patients.

In otolaryngology, training often involves simulation in animal specimens, human cadavers, and artificial models to facilitate learning surgical procedures, reducing the time needed to acquire essential skills. Simulated training has become integral to medical education, particularly in microsurgical techniques, such as microlaryngeal surgery. These procedures, also known as phonomicrosurgery, are performed on the vocal folds using microscopic visualization and precision instruments with long shafts and millimetric tips.
