  • Bronchial Leiomyoma: Importance of Preoperative Biopsy for Lung Preserving Surgery. [Case Reports]
    Oman Med J. 2022 Nov; 37(6):e445.Al Kindi AH, Al Ibrahim MT, … Al Ajmi R
  • Tracheobronchial leiomyoma is a rare tumor of the airway. They arise from the lower respiratory tract tissue of the bronchi, trachea, and lung. Symptomatology is based on the degree of endoluminal bronchial obstruction, and surgical resection is generally the mainstay of treatment. We present the case of a 33-year-old male who suffered from chronic cough and breathlessness for two years caused by…
  • Aerodynamic-induced Effects of Artificial Subglottic Stenosis on Vocal Fold Model Phonatory Response. [Journal Article]
    J Voice. 2022 Dec 07 [Online ahead of print]Hilton BA, Thomson SL
  • CONCLUSIONS: Consistent with previous computational studies, this study found that aerodynamic, acoustic, and vibratory responses of self-oscillating VF models were largely unaffected by SGS until approximately 80% to 90% obstruction, and significantly affected at higher obstructions. This suggests that Grades I and II stenoses are unlikely to introduce subglottic airway aerodynamic disturbances that are sufficient in and of themselves to significantly alter phonatory output. The SGS model introduces a framework for future benchtop studies involving subglottic and supraglottic airway constrictions.
  • In utero Treatment of Congenital High Airway Obstruction Syndrome via Fetal Laryngoscopy and EXIT Procedure. [Case Reports]
    Fetal Diagn Ther. 2022; 49(9-10):385-393.Sabra R, Gheorghe CP, … Chmait RH
  • CONCLUSIONS: The primary goal of fetoscopic airway evaluation and intervention is not necessarily to perform definitive stabilization of the airway but rather to achieve sufficient decompression of the trachea to reverse fetal hydrops and salvage pulmonary development. In utero fetoscopic treatment may allow for prolongation of the pregnancy with delivery at or near term via EXIT procedure for definitive neonatal airway stabilization.

  • Laryngotracheal stenosis (LTS) is a narrowing of the upper airway between the larynx and the trachea with potentially devastating consequences, including respiratory failure, cardiopulmonary arrest, and death. The upper airway is comprised of the larynx, glottis, subglottic region, and trachea. The trachea is a cylindrical-shaped tube with an anterior cartilaginous wall formed by c-shaped rings a…
  • Successful surgıcal management of a giant neck teratoma in a newborn Baby: A case report. [Case Reports]
    Ann Med Surg (Lond). 2022 Oct; 82:104694.Ali IM, Yaşar M, … Dırken ES
  • Neck tumors in newborns are very rare. Teratomas usually include all three germ cell layers, as well as tissues that are not native to the anatomic site of genesis. Teratomas of the head and neck make up a smaller percentage of congenital teratomas. Because of the external compression that oropharyngeal or neck masses produce, they can cause serious airway obstruction. In addition, the larynx or …

    StatPearls. StatPearls Publishing: Treasure Island (FL)O CathainEadaoinENYU LangoneGaffeyMegan M.MMNYU Langone Medical CenterBOOK
  • The upper airway consists of the nasal cavities, oral cavity, pharynx, and larynx. The pharynx is further subdivided into the nasopharynx, oropharynx, and hypopharynx. The larynx is divided into three regions, dependent on their relationship to the vocal cords (glottis). These areas are the supraglottis, glottis, and subglottis. The supraglottis consists of the epiglottis, the arytenoids, the ary…
  • Vascularized Tracheal Transplantation: A Twenty Month Follow Up. [Journal Article]
    Laryngoscope. 2022 Oct 14 [Online ahead of print]Genden EM, Harkin T, … Florman SS
  • CONCLUSIONS: Twenty months after single-staged vascularized tracheal transplantation, the trachea is functional and the patient breathes without the need for a tracheostomy or stent. Single-staged long-segment tracheal transplantation is a viable option for tracheal defects that are not amenable to conventional reconstructive techniques.
  • Tracheobronchopathia Osteochondroplastica: A Rare, Underrecognized Entity. [Case Reports]
    Cureus. 2022 Sep; 14(9):e28832.Patel PM, Jean ME, … Patel SP
  • Tracheobronchopathia Osteochondroplastica (TO) is an extremely rare condition characterized by the presence of nodules made of bone and cartilage within the submucosa of the tracheobronchial wall. These protuberant nodules inside the trachea and bronchi can lead to airway obstruction, resulting in patients who experience recurrent respiratory systems and infections. The exact etiology is unknown.…

  • StatPearls: Subglottic Stenosis [BOOK]
    StatPearls. StatPearls Publishing: Treasure Island (FL)JagpalNitishNNassau University Medical CenterShabbirNadeemNNassau University Medical CenterBOOK
  • Subglottic stenosis can be defined as the narrowing of the upper airway, which lies between the vocal folds and the lower border of the cricoid cartilage. Normally, the subglottic lumen is 4.5 mm to 5.5 mm in a full-term neonate, while a 3.5 mm lumen is normal in a premature neonate. A subglottic diameter of 4 mm or less in a full-term neonate is considered as narrow. Causes of subglottic stenosi…
  • Traumatic injuries to the trachea and bronchi: a narrative review. [Review]
    Mediastinum. 2022; 6:22.Antonescu I, Mani VR, Agarwal S
  • CONCLUSIONS: Definitive diagnosis of traumatic tracheo-bronchial injuries usually involves direct visualization through liberal use of bronchoscopy in addition to cross-sectional imaging to evaluate for associated injuries, notably to the great vessels and esophagus. Important considerations for management include concerns for airway obstruction, uncontrolled air leak, and mediastinitis. Early repair of injuries recognized acutely is favored in attempts to prevent the development of airway stenosis. Key operative principles include exposure, conservative debridement to preserve length when possible, creation of a tension-free anastomosis, preservation of the blood supply, and creation of a tracheostomy, particularly in polytrauma patients. An interposition muscle flap is also required, specifically in the setting of combined esophageal and airway injuries. Patients with penetrating injuries tend to have more favorable outcomes, possibly on account of fewer concomitant injuries. Selective non-operative management is also an option in the subset of patients with iatrogenic injuries to the posterior membranous wall of the trachea, and includes broad-spectrum antibiotics and surveillance bronchoscopy.

    StatPearls. StatPearls Publishing: Treasure Island (FL)BurtonLauren V.LVUTHSCSilbermanMichaelMUniversity of TennesseeBOOK
  • Bacterial tracheitis was first described in medical literature in the 1920s, despite the name not being coined until much later. The disease was initially referred to as acute laryngotracheobronchitis. Bacterial tracheitis, also known as bacterial croup, acute laryngotracheobronchitis, or membranous croup, is a potentially lethal infection of the subglottic trachea. It is often a secondary bacter…
