Transnasopharyngeal positive pressure ventilation during balloon dilation of severe subglottic stenosis in a low-weight infant: a case report

Using a nasopharyngeal airway assisted positive pressure ventilation can effectively maintain oxygenation and surgical access during pediatric ASGS interventions, proposing a novel ventilation strategy for complex airway procedures. While demonstrating procedural feasibility in this critical scenario, larger-scale prospective studies are required to validate its efficacy and safety profile across varying stenosis severities.
