Granulomatosis with polyangiitis (GPA) is an autoimmune disease characterized by necrotizing granulomatous inflammation. Subglottic stenosis, which is defined as narrowing of the airway below the vocal cords, has a frequency of 16–23% in GPA. Herein,...
Complete subglottic stenosis is often managed with surgical resection. However, involvement of the high subglottis can limit candidacy for open resection, and there are few treatment options for these patients. We refined an endoscopic approach that...
Laryngotracheal stenosis (LTS) is a complex and heterogeneous disease whose pathogenesis remains unclear. LTS is considered to be the result of aberrant wound-healing process that leads to fibrotic scarring, originating from different aetiology. Alth...
Subglottic stenosis (SGS) is a rare yet potentially life-threatening condition that requires prompt identification and treatment. One of the primary symptoms of SGS is a respiratory sound that is tonal. To better understand the effect of SGS on expir...
Pediatric subglottic stenosis (SGS) remains a significant cause of upper airway obstruction in infants and children, most commonly resulting from prolonged endotracheal intubation. Although open airway reconstruction procedures such as laryngotrachea...
This study investigates the impact of subglottic stenosis (SGS) on voice production using a subject-specific laryngeal and airway model. Direct numerical simulations of fluid–structure–acoustic interaction were employed to analyze glottal...
An in-house 3D fluid–structure–acoustic interaction numerical solver was employed to investigate the effect of subglottic stenosis (SGS) on dynamics of glottal flow, vocal fold vibration and acoustics during voice production. The investigation focuse...
Granulomatosis with polyangiitis (GPA) is a multi-organ disease which mostly affects lungs, kidney, and head and neck region. We report a rare case of acute laryngeal dyspnea and rapidly progressive pulmonary changes as first manifestations of diseas...
Subglottic stenosis represents a challenging clinical condition in otolaryngology. Although patients often experience improvement following endoscopic surgery, recurrence rates remain high. Pursuing measures to maintain surgical results and prevent r...
Background: Eosinophilic esophagitis (EoE) is a chronic type 2 immune-mediated esophageal disease defined by esophageal dysfunction and eosinophil-predominant inflammation. Beyond classic gastrointestinal symptoms, patients may present with aerodiges...
Background/Objectives: To assess the safety and efficacy of submucosal mitomycin C (MMC) injection as an adjunct in patients undergoing endoscopic treatment for laryngotracheal stenosis (LTS). Methods: All patients affected by LTS receiving endoscopi...
Objective: 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 tra...
Objectives: Our aim was to investigate the diagnostic challenges and management of relapsing polychondritis (RP) with airway involvement, highlighting the need for accurate diagnosis and effective intervention to prevent severe complications. Methods...
Background/Objectives: GPA is a PR3-ANCA–predominant small vessel vasculitis with organ involvement. Real-world, single-centre data are needed to interpret evolving therapies and phenotype patterns in national conditions. Material and Methods:...
Background: Airway stenosis is a known complication of prolonged intubation in hospitalized patients. With the high rate of intubations in patients with COVID-19 pneumonia, laryngotracheal stenosis (LTS) is a complication of COVID-19 that drastically...

Objectives: To describe a rare case of delayed diagnosis of a subglottic foreign body (FB) in an adult, resulting in subglottic stenosis, and to evaluate the effectiveness of Suspension Microlaryngoscopy (SML) as a minimally invasive technique for it...
Many authors have reported that tracheal stenosis is a complication that can follow tracheal intubation in both adults and children. The symptoms, when they do appear, can be confused with asthma, with subsequent treatment providing only mild and inc...
Many of the patients with COVID-19 have suffered respiratory distress requiring prolonged endotracheal intubation (ETI) resulting in laryngotracheal complication with an impact on breathing, phonation, and swallowing. Our aim is to describe laryngeal...
Introduction: While most patients with iatrogenic tracheal stenosis (ITS) respond to endoscopic ablative procedures, approximately 15% experience a recalcitrant, recurring disease course that is resistant to conventional management. We aimed to explo...
Background and objectives: During the COVID-19 pandemic, we followed with concern the evolution of several children diagnosed with Multisystem Inflammatory Syndrome in Children (MIS-C). The purpose of this study is to describe the evolution of MIS-C...
Background. Post-intubation cicatricial laryngeal stenosis (PICLS) represents one of the most severe long-term complications of pediatric airway management. By systematically analyzing clinical and procedural variables across different grades of PICL...
Background: Tracheobronchial stenosis is a significant complication in granulomatosis with polyangiitis (GPA), a systemic vasculitis that primarily affects the upper respiratory tract, kidneys, and lungs. The involvement of the tracheobronchial tree...
Introduction: Benign subglottic/tracheal stenosis (SG/TS) is a life-threatening condition commonly caused by prolonged endotracheal intubation or tracheostomy. Invasive mechanical ventilation was frequently used to manage severe COVID-19, resulting i...
Introduction: Laser surgery of the larynx is currently the standard of clinical practice in a multitude of procedures. Lasers with photoangiolytic properties have a wide application in endolaryngeal lesions. One of their most prominent features is th...
Background and Objectives: Anesthesia for pediatric microlaryngoscopy/direct laryngoscopy and bronchoscopy (DLB) is very challenging. Airway management methods can vary from tubeless techniques to endotracheal intubation. In this study, we analyzed t...
Laryngeal pathology requires individualized management because the larynx integrates airway protection, phonation, swallowing, and respiratory function within a compact and highly variable anatomical framework. This narrative review examines how lary...
Diffuse alveolar hemorrhage (DAH), a catastrophic complication of connective tissue disorders (CTDs), manifests as rapid-onset hypoxemia, alveolar infiltrates, and progressive bleeding into the airways. While immune-mediated alveolar–endothelia...
Granulomatosis with polyangiitis (GPA) is a systemic vasculitis frequently associated with serum anti-neutrophil cytoplasmic antibodies (ANCAs), particularly anti-proteinase 3 (PR3). Multisystem involvement is typical, although disease onset with sim...
During the current pandemic, we witnessed a rise of post-intubation tracheal stenosis (PITS) in patients intubated due to COVID-19. We prospectively analyzed data from patients referred to our institution during the last 18 months for severe symptoma...
