INTRODUCTION: Acquired stenosis of the airway is a common complication after endotracheal intubation. Endoscopic dilation has been accepted as the treatment of choice in cases detected precociously. Our goal is to know the current status of the patients treated in our hospital with endoscopic dilation in the last 10 years. MATERIAL AND METHODS: Retrospective cohort study of patients with subglottic and tracheal acquired stenosis (STAS) early treated endoscopically with balloon dilation at our center in the last 10 years...

Importance: Endoscopic dilation is the mainstay treatment strategy for subglottic and proximal tracheal stenosis (SGS/PTS). Its major limitation is restenosis requiring repeated surgery. Intralesional steroid injection (ISI) is a promising adjunctive treatment aimed at prolonging the effects of dilation. Objective: To evaluate the association of serial in-office ISI after endoscopic dilation with surgery-free interval (SFI) in adults with SGS/PTS. Design, Setting, and Participants: A retrospective study of adults with SGS/PTS who underwent at least 2 consecutive in-office ISI at the University of Southern California, Keck School of Medicine, over a 3-year period was conducted...

Context Hemorrhage is one of the potentially fatal complications of tracheostomy. A rare but lethal cause of tracheostomy related bleeding is hemorrhage from the innominate artery. This occurs following tracheo-innominate artery fistula (TIF) formation, which is associated with a mortality rate of more than 85%. Here, we report the case of an individual with tetraplegia and a tracheostomy who died as a result of innominate artery hemorrhage. This case highlights the possible causes and interventions associated with this complication, and provides insight into tracheostomy related bleeding in patients with spinal cord injury (SCI)...

Eosinophilic angiocentric fibrosis (EAF) is a rare, benign condition affecting the respiratory mucosa and is generally characterized by a locally destructive growth. We present a case of a lady with a saddle nose deformity that had for many years been treated as granulomatosis with polyangiitis (GPA), of which saddle nose deformity is a classic feature. At the time of surgery, she was found to have subglottic stenosis another classic feature of GPA, however, histology demonstrated EAF. We discuss the difference between the two conditions and highlight the importance of making the correct diagnosis...

Asthma is a heterogeneous disease, usually characterized by chronic airway inflammation. Various clinical conditions can mimic asthma, such as foreign body aspiration, subglottic stenosis, congestive heart failure, diffuse panbronchiolitis, aortic arch anomalies, reactive airway dysfunction syndrome, chronic obstructive pulmonary disease, retrosternal goiter, vocal cord tumors, other airway tumors, and vocal cord dysfunction. Upper airway obstruction can be a life-threatening emergency. Here, we present the case of a 58-year-old female with recurrent hospital visits for wheezing and exacerbations of asthma, who was later found to have a vocal cord nodule confirmed to be squamous cell carcinoma, which was mimicking like asthma...

The Montgomery T-tube poses a challenge to anesthesiologists because of loss of anesthetic gases through the open proximal end of the vertical limb and lack of standard anesthesia circuit connectors. Here, we present a case of a 25-year-old woman with a reported history of accidental strangulation 18 months previously. The patient had a metallic tracheostomy tube in situ due to the development of tracheal stenosis. Computed tomography showed significant narrowing in a 7-8-mm segment, 2 cm proximal to the tracheostomy tube in situ...

BACKGROUND: Tracheal tube cuff pressures exceeding the perfusion pressures of the tracheal mucosa have been associated with complications such as sore throat, tracheal mucosa ulcers, tracheal rupture, and subglottic stenosis. Despite appropriate inflation, many factors can increase the tracheal cuff pressure during mechanical ventilation. This prospective observational cohort study was designed to test the hypothesis that during a clinical model of decreasing respiratory compliance, the pressure within the endotracheal tube cuff will rise in direct relationship to increases in the airway pressures...

OBJECTIVES: Subglottic stenosis (SGS) is one of the most common airway disorders in pediatric patients. Currently, treatment decisions rely primarily on the Cotton-Myer scale, which classifies SGS severity based on percentage reduction in airspace cross-sectional area (CSA). However, the precise relationship between upper airway resistance and subglottic CSA is unknown. We hypothesize that airway resistance can be described by the Bernoulli Obstruction Theory, which predicts that airway resistance is inversely proportional to airspace CSA ( R∝A-1) in cases of severe constriction...

Unanticipated difficult airway in a neonate is a challenging situation with many difficulties because of inherent anatomical variations. To complicate the situation there is a lack of appropriate equipment, expertise and established guidelines on the management of difficult airway in neonates and infants. There are few published reports regarding the use of available devices for emergency front-of-neck access. We report the case of airway management of a neonate with an unanticipated finding of subglottic stenosis...

BACKGROUND: Granulomatosis with polyangiitis (GPA) is associated with development of subglottic stenosis in about one-fourth of all patients. Although endoscopic management is the primary treatment method for tracheobronchial stenosis, some patients have refractory disease, and tracheostomy is required. It is unclear if laryngotracheal resection and reconstruction (LTRR) can be safely performed in patients with GPA. METHODS: A retrospective review was performed of 11 patients with GPA undergoing LTRR...
