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...

Nasopharyngeal stenosis is a rare sequela of extra-laryngeal tuberculosis that can adversely impact the quality of life of afflicted patients. Relying solely on the oropharyngeal airway, patients often complain of inspiratory dryness and decreased sensation of airflow as the nasal mucosa and turbinate complex is entirely excluded from the breathing mechanism. Often times, the oropharyngeal inlet can be narrowed as well, limiting the air flow through the oropharyngeal airway. In those circumstances, patients often require tracheostomy for establishment of a reliable airway...

Microcephalic osteodysplastic primordial dwarfism type 1 (MOPD1) is an uncommon cause of microcephaly and intrauterine growth retardation in a newborn. Early identifying features include but are not limited to sloping forehead, micrognathia, sparse hair, including of eyebrows and short limbs. Immediate radiological findings may include partial or complete agenesis of the corpus callosum, interhemispheric cyst and shallow acetabula leading to dislocation. Genetic testing displaying a mutation in RNU4ATAC gene is necessary for definitive diagnosis...

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...

Glottic stenosis is a fixed, focal narrowing at the level of the laryngeal inlet, the true vocal cords. It may be either congenital or acquired and be related to a wide range of etiologies. The stenosis may be either anterior, posterior, or in rare cases, complete. Isolated glottic stenosis is rare; lesions often involve adjacent regions, namely the subglottis. A diagnosis is made from careful history and examination, including evaluation by microlaryngoscopy and bronchoscopy. The management of glottic stenosis is challenging and should be tailored to each individual case...

INTRODUCTION: Congenital high airway obstruction syndrome (CHAOS) is a rare, usually lethal abnormality characterized by complete or near-complete intrinsic obstruction of the fetal airway. Laryngeal atresia is the most frequent cause, but other etiologies include laryngeal or tracheal webs, laryngeal cyst, subglottic stenosis or atresia, tracheal atresia and laryngeal or tracheal agenesis. When antenatal diagnosis of possible upper airway obstruction is made, specific type of obstruction is rarely determined making the term CHAOS introduced by Hedrick et al in 1994 more appropriate...

OBJECTIVES/HYPOTHESIS: Idiopathic subglottic stenosis (iSGS) is a rare and devastating extrathoracic obstruction involving the lower laryngeal and upper tracheal airway. It arises without known antecedent injury or associated disease process. Persistent mucosal inflammation and a localized fibrotic response are hallmarks of the disease. Despite the initial clinical description of iSGS more than 40 year ago, there have been no substantive investigations into the pathogenesis of this enigmatic and progressive airway obstruction...

OBJECTIVES/HYPOTHESIS: Idiopathic subglottic stenosis (iSGS) is an unexplained obstruction involving the lower laryngeal and upper tracheal airway. Persistent mucosal inflammation is a hallmark of the disease. Epithelial microbiota dysbiosis is found in other chronic inflammatory mucosal diseases; however, the relationship between tracheal microbiota composition and iSGS is unknown. Given the critical role for host defense at mucosal barriers, we analyzed tissue specimens from iSGS patients for the presence of microbial pathogens...
