Article Abstract
Objective: Full-thickness resection and skin grafting of the laryngotracheal junction, the "Maddern Procedure," can be used to treat patients with recalcitrant laryngotracheal stenosis. We report the long-term surgical outcomes of this procedure.
Methods: A consecutive series of 27 females with idiopathic, iatrogenic, or vasculitic subglottic stenosis who underwent the Maddern procedure between 2012 and 2023 were retrospectively reviewed. Airway outcome was assessed using the Modified Medical Research Council Dyspnea (mMRC) Scale. Secondary outcomes included voice, swallowing, mucus management, complications, and the need for subsequent airway surgery.
Results: Most patients had idiopathic subglottic stenosis (n = 20, 74.1%), followed by vasculitic (n = 4, 14.8%) and intubation-related (n = 3, 11.1%) etiologies. Patients had an average of 7.3 (SD 3.4) endoscopic procedures before undergoing the Maddern procedure. Mean pre-Maddern inter-treatment interval was 7.5 months (SD 3.4). The median follow-up was 6.6 years (interquartile range 0.75-11.3). The mMRC dyspnea scale improved from 2.7 (SD 0.73) to 0.52 (SD 0.85). The five-year recurrence-free rate was 63%. It differed between etiologies, ranging from 83% for idiopathic stenosis to 67% for intubation-related and 0% for vasculitis-related stenoses. During the first 4 years after Maddern, 67% of patients reported daily cough and the need to use nebulizers regularly.
Conclusion: The Maddern procedure is an effective and durable option for patients with idiopathic subglottic stenosis. Careful screening of patients with presumed idiopathic subglottic stenosis for possible underlying auto-immune conditions remains important when considering patients for this procedure.
Level Of Evidence: Level 4.

Subglottic stenosis (SGS) is a significant cause of breathing obstruction in pediatric patients, predominantly acquired due to prolonged endotracheal intubation. The primary aim of this study was to evaluate long-term quality of life in children after Balloon Dilatation for subglottic and tracheal stenosis. This cross-sectional study evaluated pediatric patients with SGS or tracheal stenosis treated with balloon dilatation at a children's medical center in Tehran, Iran, from 2014 to 2021.

Laryngotracheal stenosis (LTS) has been described as a complication of prolonged intubation. Early in the COVID-19 pandemic, many patients were intubated and ventilated for a long period, often in the prone position. To investigate the physical effects of prone versus supine positioning and its possible correlation to LTS, this research used two Thiel-embalmed cadavers, one male and one female, and a novel pressure sensor device, to directly measure the force applied by an endotracheal tube onto the posterior glottis.

Objective: The study aimed to evaluate the clinical outcomes of endoscopic posterior cricoid split with costal cartilage grafting (EPCSCG) in pediatric patients with bilateral vocal cord paralysis (BVCP) and compare these results with those in the existing literature.
Methods: This retrospective case series included pediatric patients (≤18 years) who underwent EPCSCG between 2017 and 2024 at a tertiary care center. Data were extracted from operative reports, clinical notes, and endoscopy records.
