Congenital nasal pyriform aperture stenosis (CNPAS) is a very rare condition of the newborn, in which the nasal pyriform aperture is narrowed by bony overgrowth of the nasal process of the maxilla (Figure 1). As the narrowest point of the nasal airway, a small change in its diameter may significantly increase nasal airway resistance. As infants are obligate nose breathers for the first three mo...

Background: Subglottic stenosis is among the most common airway problems in children, i.e., acquired or congenital. More than 90% of cases are secondary to endotracheal intubation and occur iatrogenically. an unexpected problem that requires timely diagnosis intervention. Most subglottic children mild moderate. Case Presentation: The presented patient was a 10-year-old child who, after long due...

Background: Tracheal stenosis is the obstruction of airway and need a proper diagnosis, management treatment approach. Objective: To diagnose manage repair tracheal stenosis. Study Design: Comparative analytical study Place Duration Study: Department Thoracic Surgery, Sandeman Provincial Hospital Quetta from 1st July 2020 to 30th June 2021. Methodology: Forty seven patients were divided into tw...

BACKGROUND Patients with unilateral cleft lip and palate (CLP) deformities commonly develop nasal airway obstruction, necessitating septoplasty at the time of definitive rhinoplasty. We assessed the contribution of the bony septum to airway obstruction using computed tomography (CT) and cone beam CT (CBCT). METHODS A 2-year retrospective review of all subjects with unilateral CLP who underwen...

Prefabricated composite free flaps for complex airway reconstruction have been described for an adult series at our institution. We extended this approach to a pediatric patient with lifelong subglottic stenosis who had failed previous open airway reconstructions. A staged procedure was utilized in which a composite graft was created using conchal cartilages and a radial forearm free flap. This...

Central airway stenosis caused by compression due to mediastinal cyst is rare. Direct real-time endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) is a minimally invasive method for tissue sampling of the mediastinum. Using this new therapeutic modality, the mediastinum can be punctured repeatedly and safely under local anesthesia with real-time guidance. Cystic lesion...

conclusions to enhance the follow-up rate, three strategies were proposed: patient-focused strategies such as emphasizing patient education upon discharge and providing rewards; structural-focused strategies such as scheduling home visits and uploading questionnaires onto the research center’s website; and provider-focused strategies such as selecting coordinators with good communication skills...

The computational fluid dynamics method, which provides an estimation of the pressure drop in the airway before and after the stent implantation, is proposed in this study. This method is based on the finite volume model. The pressure field was solved by the Navier-Stokes equations. The proposed methodology was evaluated in seven health people (control group) and in fourteen patients who were a...
