mendations about external diameter.2 While internal diameter is important for the airway resistance, the magnitude of the external diameter may play a role in the development of postintubation airway edema, postintubation croup and subglottic stenosis in pediatric patients. Therefore, when choosing a certain size of tracheal tube in children, both internal and external diameters should be taken...

OBJECTIVE To experimentally develop tracheal stenosis and malacia to test new models of tracheal stents. METHODS We resected three cartilaginous rings from the cervical trachea of dogs in group A (n = 5) and six rings in group B (n = 4) to produce malacia. The mucosa of the region with malacia then received applications of a solution of sodium hydroxide (NaOH) at 23%, and the animals were acc...

Arytenoidectomy, or the partial removal of arytenoid cartilage, is a surgical procedure performed to treat bilateral vocal fold immobility. It can widen posterior glottis, which important as an airway, and maintain voice quality more effectively than lateralization. In addition, it expected have permanent effect without possibility relapse due breakage traction threads subsequent infection. Whe...

Brachycephalic obstructive airway syndrome (BOAS) in dogs indicates a particular set of upper abnormalities found brachycephalic (e.g., French bulldogs). Stenotic nares is one the primary BOAS-related restricting functional breathing affected dogs. For severe stenosis, rhinoplasty required to increase accessibility external nostril air; however, specific improvement from surgery terms respirato...

Acquired stenosis of the trachea or bronchus in newborn infants is a possible complication of perinatal intubation and mechanical ventilation. Although the exact pathophysiology is unknown, stenosis formation seems to be initiated by pressure necrosis. Prematurity is thought to be an important risk factor for acquired airway stenosis. Management of stenotic lesions may be conservative, surgical...

There are various types of airway stents for central stenosis (CAS) due to lung cancer. The placement an stent is known improve the patients' quality life (QOL) and activities daily living (ADL). Thus, we report 4 cancer cases with CAS managed Ultraflex stent, a type in which 3 patients showed improvement performance status (PS) could be discharged home. Since evidence stenting scarce, reported...

OBJECTIVES To describe our management of complex glottic stenosis in tracheotomy dependent children with severe recurrent respiratory papillomatosis. METHODS Retrospective chart review at a tertiary care children's hospital. RESULTS Three children with complex glottic stenosis secondary to severe recurrent respiratory papillomatosis were treated at our institution since 2011. Two patients h...

OBJECTIVES To describe oropharyngeal stenosis (OPS), a potential complication of multilevel, single-stage upper airway surgery involving lingual tonsillectomy in children, and to discuss the manner in which OPS may be managed successfully. DESIGN Case series with an average follow-up of 12 months. SETTING Tertiary care children's hospital. PATIENTS Medical charts were reviewed for 104 pat...

To evaluate the effects of current supportive care measures for the adult respiratory distress syndrome (ARDS) upon the upper airway, we studied 30 survivors of ARDS. All patients were interviewed and examined and performed inspiratory and expiratory maximal flow-volume curves more than six months after the onset of ARDS. Three women had developed symptomatic upper airway obstruction due to lar...

BMJ Case Rep Published online: [please include Day Month Year] doi:10.1136/ bcr-2013-009650 DESCRIPTION A 64-year-old woman was referred to our department with progressive dyspnoea and haemoptysis. Half a year ago a metallic endobronchial stent was inserted in the left main bronchus due to a benign stenosis after sleeve resection for lung cancer....
