Laryngotracheal stenosis has not been reported previously as a manifestation of spondyloepiphyseal dysplasia. Two recent cases are reported detailing the upper airway pathology encountered. The clinical features of spondyloepiphyseal dysplasia are reviewed in an attempt to develop a treatment protocol for such patients with laryngotracheal stenosis. The ultrastructural abnormalities found in these patients' cartilages are emphasized. Caution is advised before attempting laryngotracheoplasty.

Background: An endoscopic screening program following successful weaning from prolonged mechanical ventilation maintained through endotracheal tube (ET; ) may be justified to assess the upper (laryngotracheal) airway in children who may not always be symptomatic for intubation-related complications.
Objectives: To evaluate effects of prolonged intubation in children through endoscopic screening of the laryngotracheal airway.
Methods: In this cross-sectional pilot project, children (2 months-12 years) successfully extubated following prolonged intubation were selected, irrespective of having symptoms, for a 1-time flexible nasolaryngoscopy at third to sixth month post-extubation (follow-up window).

Objective: To develop a reproducible survival rabbit model for laryngotracheal stenosis (LTS).
Methods: Seventy New Zealand white (NZW) rabbits were randomly divided into experimental groups ( = 30) and a control group ( = 40). In experimental groups, a nylon brush was inserted retrograde from the tracheotomy through the subglottis and rotated until a full layer circumferential mucosal injury to cartilage exposure, assisted by fiberoptic laryngoscopy (FOL) visualization.

Subglottic and posterior glottic stenosis (PGS) narrows distinct areas of the larynx, while bilateral vocal fold immobility (BVFI) is characterized by static cords. Treatments include open surgeries and newer endoscopic methods, offering comparable safety, quicker recovery, and fewer complications. This study assesses the decannulation rate of endoscopic posterior cricoid split with posterior cartilage grafting (EPCCG) in pediatric patients with posterior glottic stenosis, subglottic stenosis (SGS), and BVFI.

Objectives: Idiopathic subglottic stenosis (ISS) is an airway stricture between larynx and trachea, within 1 cm from the vocal cords. Resection-reconstruction present technical issues because of the need to resect the anterior portion of the cricoid cartilage, but not the posterior plate beyond which the recurrent laryngeal nerves access the vocal cords. The main surgical challenge consists of the minute airway calibre short below the cords, ensuing after the resection.
