OBJECTIVES/HYPOTHESIS: Whereas mechanical (traumatic) causes of laryngotracheal stenosis (LTS) are identified based on history, autoimmune laryngotracheal stenosis (aLTS) and idiopathic laryngotracheal stenosis (iLTS) are often more difficult to differentiate. The objective of this study was to evaluate serologic testing in a large cohort of nonmechanical LTS patients to determine which tests, if any, lead clinicians to the etiology of the LTS. STUDY DESIGN: Retrospective chart review...

Importance: Adult laryngotracheal stenosis (LTS) is typically managed surgically, but some patients fail treatment because of rapid restenosis or granulation tissue formation. The need for frequent surgery or tracheostomy reduces the quality of life in these patients and poses a significant challenge for the treating physician. New adjuvant treatments are required to reduce the surgical burden of this condition. Objective: To examine whether patients with rapidly recurrent nonvasculitic LTS who fail surgical management of their stenosis (ie, requiring dilation more frequently than every 6 months) experience longer intervals between surgical procedures when receiving adjuvant treatment with low-dose methotrexate...

OBJECTIVES/HYPOTHESIS: To determine if open surgical treatment options for adult and adolescent laryngotracheal stenosis are more successful than endoscopic procedures. STUDY DESIGN: Systematic review. METHODS: Embase and MEDLINE were searched for publications on adult and adolescent patients (>13 years old) with laryngotracheal stenosis. Cause of stenosis (intubation, idiopathic, or trauma) and treatments (open laryngotracheal resection with anastomosis, open laryngotracheal reconstruction with expansion grafting, or endoscopic procedures) were included...

Localized tracheobronchial amyloidosis is a rare disease that results from submucosal deposition of insoluble amyloid proteins in the large airways. Amyloidosis affecting the larynx and subglottic space typically results in unilateral, nodular vocal cord infiltration. It rarely can present with bilateral vocal cord involvement and can progress to lifethreatening respiratory failure due to upper airway obstruction. In these patients, typical treatment modalities such as CO2 laser ablation are often ineffectual...

Although it has been speculated that the tracheal obstructions and asphyxiation during acute infectious laryngotracheitis (ILT) are due to mucoid plugs/casts formed by mucus hypersecretion, there are no reports demonstrating this. Hence, in the present study, we first examined if the main respiratory mucins, MUC5AC and MUC5B, are expressed in the mucosae of larynx, trachea and bronchi of mock-inoculated and ILTV infected chickens. Second, the tracheas with plugs/casts were stained for mucins (MUC5AC and MUC5B) and nuclear material (traps)...

INTRODUCTION: The goal of this retrospective study is to compare the management and outcome of surgical treatment of laryngotracheal stenosis in children and infants with and without an associated neurological disorder. PATIENTS AND METHOD: In a series of children operated on for subglottic stenosis (SGS), patients with an associated neurological disorder were identified. The following criteria were compared in children with and without neurological disease: grade of stenosis, age, technique (Crico-Tracheal Resection (CTR), Laryngo-Tracheo-Plasty (LTP) in single and 2 stage, laser), analyzing duration, preoperative tracheostomy, decannulation rate, preoperative gastrostomy, and number of days in intensive care unit and in hospital...

Thyroid carcinoma is one of the most common cancer in the head and neck and its incidence shows an increasing tendency. Due to the special anatomical location of thyroid carcinoma, patients will have a bad prognosis outcome when cancer invades larynx and trachea. Surgical treatment is still a preferred therapy for thyroid carcinoma with laryngotracheal invasion, because it has the advantages such as high survival rate, low recurrence rate, relieving of airway obstruction, improving of postoperative quality of life...

OBJECTIVES: Repair of laryngotracheal stenosis with pronounced side-to-side narrowing and involvement of the glottis is challenging and usually requires laryngotracheal reconstruction with rib cartilage interpositions. This technique, as first described by Couraud, needs prolonged postoperative stabilization with Montgomery T-tubes, imposing significant morbidity and discomfort on patients. We describe our initial experience with a modified laryngotracheal reconstruction technique that avoids the need for prolonged postoperative stenting...

Backyard poultry is regaining popularity in Europe and increased interest in the health and management of non-commercial farms has resulted. Furthermore, commercial poultry farm owners have become concerned about the risk represented by contagious animal diseases that nearby backyard poultry could transmit. Fifty-one voluntary backyard chicken farms were visited between October 2012 and January 2013. Blood samples and individual cloacal swabs were collected from 457 chickens. In 44 farms (86%), one or more of the tested chickens had antibodies against avian encephalomyelitis and chicken infectious anemia viruses, 24 farms (47%) had chickens seropositive for infectious bronchitis virus, 10 farms (20%) had chickens seropositive for infectious bursal disease virus, six farms (12%) had chickens seropositive for infectious laryngotracheitis virus and two farms (5...

Recurrent tracheoesophageal fistula (TEF) is still difficult to diagnose and repair. In almost all cases, recurrence appears relatively soon after the primary surgery. We herein describe a case of recurrent TEF that appeared 10 years after the primary repair. At 2 years of age, the patient suffered from mental retardation due to encephalitis and developed a hiatus hernia with gastro-esophageal reflux. He underwent the repair of a hiatus hernia and fundoplication at 3 years of age. However, the hiatus hernia recurred 6 months after the operation...

OBJECTIVES/HYPOTHESIS: Laryngotracheal stenosis (LTS) is a chronic fibrotic disease characterized by fibroblast proliferation, collagen deposition, and matrix remodeling in the lamina propria of the larynx and/or trachea. Current medical therapies are limited by a poor understanding of the effector cell's (fibroblasts) cellular biology and metabolism. The purpose of this study was to compare cellular proliferation, function, and metabolism between normal and LTS-derived fibroblasts in vitro...

PURPOSE OF REVIEW: Adult laryngotracheal stenosis (LTS) is a potentially life-threatening disorder that can be difficult to diagnose and treat. Much is unknown regarding the etiology of airway stenosis, and while many patients do well with standard surgical management, the recurrence rate is significant. Few medical therapies exist, but there is a growing need. RECENT FINDINGS: Several basic science studies have shown a role of inflammatory signaling pathways in the development of LTS...
