BACKGROUND: Tracheomalacia (TM) is a condition of excessive tracheal collapse during exhalation. Both acquired and congenital forms of TM are believed to result from morphological changes in cartilaginous, fibrous and/or smooth muscle tissues reducing airway mechanical properties to a degree that precipitates collapse. However, neither the specific amount of mechanical property reduction nor the malacic segment lengths leading to life threatening airway collapse in TM are known. Furthermore, the specific mechanism of collapse is still debated...

Thomas Kovesi
Chronic, long-term respiratory morbidity (CRM) is common in patients with a history of repaired congenital esophageal atresia, typically associated with tracheoesophageal fistula (EA/TEF). EA/TEF patients are at high risk of having aspiration, and retrospective studies have associated CRM with both recurrent aspiration and atopy. However, studies evaluating the association between CRM in this population and either aspiration or atopy have reported conflicting results. Furthermore, CRM in this population may be due to other related conditions as well, such as tracheomalacia and/or recurrent infections...

We report a case of severe respiratory distress in a neonate who was not endotracheally intubated soon after esophageal atresia/tracheoesophageal fistula (EA/TEF) repair. In this serious situation, any form of emergency respiratory support or definitive airway management may compromise the esophageal anastomosis and fistula repair. The cause of respiratory distress in the early postoperative period after EA/TEF is multifactorial, and in this case, included symptomatic tracheomalacia, which is commonly associated with EA/TEF...

INTRODUCTION: 22q11.2 deletion syndrome (22q11.2DS) presents with complex but variable symptoms, including cardiac, immune, palatal, endocrine, cognitive, and psychiatric issues. However, an association of 22q11.2DS with structural airway abnormalities has not been formally described. The aim of this study was to document the frequency of this association. METHODS: We retrospectively reviewed medical records of patients with 22q11.2DS evaluated in the 22q and You Center at the Children's Hospital of Philadelphia between 1999 and 2015 referred to otolaryngology for an airway assessment...

PURPOSE: In severe tracheomalacia, aortopexy addresses anterior vascular compression, but does not directly address posterior membranous tracheal intrusion. We review patient outcomes of posterior tracheopexy for tracheomalacia with posterior intrusion to determine if there were resolution of clinical symptoms and bronchoscopic evidence of improvement in airway collapse. METHODS: All patients who underwent posterior tracheopexy from October 2012 to March 2016 were retrospectively reviewed...

We describe the implantation of an absorbable, custom-made stent of polydioxanone to treat tracheomalacia in a 5-month-old patient with extrinsic compression by a double aortic arch. The use of an absorbable, oversized stent treated the tracheal collapse caused by vascular compression, avoided removal procedures, and allowed the infant's growth. The use of an oversized stent prevented stent migration and gave minimal problems of granulation.

This observation reports the use of an external airway splint to treat tracheomalacia in a pediatric patient. The patient underwent a double stage laryngotracheal reconstruction however was unable to be decannulated due to severe tracheomalacia. Our purpose is to further support the use of external splinting in the treatment of tracheomalacia in a unique case involving isolated nighttime airway obstruction following laryngotracheal reconstruction.

Pediatric airway surgery is a challenging field in pediatric surgery. Laryngotracheal stenosis has a variety of congenital and acquired conditions that require precise assessment and tailored treatment for each individual patient. About 90% of acquired conditions are represented by subglottic stenosis (SGS) resulting as a complication of tracheal intubation. Congenital tracheal stenosis (CTS) is a rare and life-threatening malformation, usually associated with complete tracheal rings along a variable length of the trachea...

Abby White, Raphael Bueno
Esophageal atresia is a rare congenital anomaly, but improved surgical and critical care has resulted in survival rates exceeding 90%. Long-term survival is associated with numerous management challenges including chronic motility disorders, dysphagia, strictures, reflux, esophagitis and attendant complications, tracheomalacia and chronic restrictive lung disease, and recurrent pulmonary infections. No guidelines for adolescents and younger or older adults exist for the treatment and monitoring of this specialized patient population...

BACKGROUND: Tracheostomy is considered the airway management of choice for patients who need prolonged mechanical ventilation support. Percutaneous Dilatational Tracheotomy (PDT) is a technique that can be performed easily and rapidly at bedside and is particularly useful in the intensive care setting. The Griggs percutaneous tracheotomy is unique in its utilization of a guide wire dilator forceps. OBJECTIVE: We aimed to describe the early perioperative and late postoperative complications of PDT using the Griggs technique in patients in the intensive care unit (ICU)...

Kniest dysplasia is a type II collagen disorder that arises from a genetic mutation of the COL2A1 gene that results in short stature, midface anomalies, tracheomalacia, and hearing loss. Disruption of the normal collagen pathway can lead to many changes given its critical role in the body, and can cause complications with respect to wound healing. We present a case in which a patient with Kniest dysplasia successfully underwent multiple procedures in the head and neck region including cochlear implantation, mandibular distraction, palatoplasty, and laryngotracheal reconstruction...

The major methods are used to fix or stabilize the central airways and major bronchi with either anterior suspension and/or posterior fixation for severe tracheomalacia (TM). Many support biomaterials, like mesh and sternal plate, can be used in the surgery. But there are no specialized biomaterials for TM which must be casually fabricated by the doctors in operation. Three dimensional printing (3DP) has currently untapped potential to provide custom, protean devices for challenging and life-threatening disease processes...

Anesthetic management of critical airway stenosis is often very challenging. Extracorporeal membrane oxygenation (ECMO) may provide adequate respiratory support when conventional approaches fail. We report our experience of ECMO support for critical airway surgery. Between April 2012 and March 2015, nine patients underwent ECMO-supported airway operation. The reason for surgery was tracheal stenosis in nine patients, and tracheomalacia, tracheal tumor, and external tracheal compression by mediastinal mass in one patient each...

Chronic obstructive pulmonary disease (COPD) is one of the leading causes of disability and death worldwide. COPD exacerbation is usually treated with antibiotics, systemic corticosteroids, and inhaled bronchodilators. We present a case of recurrent COPD exacerbation that was treated repeatedly with standard therapy. Dynamic expiratory computed tomography of the chest was done, which revealed concomitant tracheomalacia. COPD and tracheomalacia may coexist during recurrent exacerbations of COPD, and delayed diagnosis can be associated with severe comorbidities...

OBJECTIVE: The solution of severe tracheobronchial obstructions in early childhood means a great challenge. Biodegradable stents were intended to be a minimally invasive temporary solution which may decrease the number of interventions and limit the possible complications of stenting procedures. However, our first experiences have brought out a new, - especially in childhood - potentially life-threatening complication of this concept. METHODS: Five SX-ELLA biodegradable polydioxanone stents was applied in three patients because of severe tracheobronchial obstruction: congenital tracheomalacia (7 day-old), acquired tracheomalacia (10 month-old), and congenital trachea-bronchomalacia (10 month-old)...
