          ABSTRACT

          Endotracheal intubation injuries are rare, but may be devastating—mostly among the pediatric patients or when these occur in the distal trachea. Such complications typify a therapeutic challenge, which, besides requiring intellectual and technical resources, takes a long time to reach a resolution. The authors present the case of a 15-year-old girl admitted with an abnormal state of consciousness due to diabetic ketoacidosis. She was submitted to endotracheal intubation with hyperinflation of the tube cuff, which rendered tracheal necrosis and detachment of the tracheal mucosa, and consequent obstruction. Later, she developed scarring retraction and stenosis. The patient was successfully treated with an endotracheal prosthesis insertion. The aim of this report is to illustrate a preventable complication.

          Subglottic stenosis.

          Subglottic stenosis (SGS) is a congenital or acquired condition characterized by a narrowing of the upper airway extending from just below the vocal folds to the lower border of the cricoid cartilage. With the introduction of prolonged intubation in neonates (mid 1960s), acquired SGS became the most frequent cause of laryngeal stenosis; unlike congenital SGS, it does not improve with time. Laryngeal reconstruction surgery evolved as a consequence of the need to manage these otherwise healthy but tracheotomized children. Ongoing innovations in neonatal care have gradually led to the salvage of premature and medically fragile infants in whom laryngeal pathology is often more severe, and in whom stenosis often involves not only the subglottis, but also the supraglottis or glottis-causing significant morbidity and mortality. The primary objective of intervention in these children is decannulation or preventing the need for tracheotomy. The aim of this article is to present a more detailed description of both congenital and acquired SGS, highlighting the essentials of diagnostic assessment and familiarizing the reader with contemporary management approaches.

            Stents for airway strictures: selection and results

            Airway stents can provide effective and timely relief in patients with central airway obstruction. Silicone based stents are the most commonly used airway stents worldwide with a long track record of safety. Metallic stents continue to evolve from the earliest uncovered versions to a variety of newly designed covered stents. Despite the availability of a variety of stent materials and designs, minimal advances have been made towards innovation in stent technology and an ideal stent has unfortunately not yet been developed. Nevertheless, the first generation of biodegradable airway stents are available, work on drug-eluted stents is in the pipeline and three-dimensional printing of a customized airway stent may be the future. In this review, we discuss selection and results for most commonly utilized airway stents.
