Early detection of laryngeal cleft in infants by novel technique of flexible endoscopy with sustained pharyngeal inflation.

Objective: We report a novel technique of flexible endoscopy with noninvasive ventilation (NIV) and sustained pharyngeal inflation (FE-NIV-SPI) in assessing aeroesophageal tracts (AET) to facilitate early detection of laryngeal clefts in infants.

Methods: Medical charts and flexible endoscopy videos of the children who were diagnosed with laryngeal cleft in a tertiary care hospital between January 2000 and December 2020 were retrospectively reviewed and analyzed. The FE-NIV-SPI technique had been applied to all these children.

Sustained pharyngeal inflation on upper airway effects in children-Flexible bronchoscopy measurement.

Objective: Sustained pharyngeal inflation (SPI) with pharyngeal oxygen and nose-closure (PhO -NC) can create positive peak inflation pressure (PIP) inside the pharyngolaryngeal space (PLS). This study measured and compared the effects of four different SPI durations in the PLS.

Methods: A prospective study, 20 consecutive children aged between 6 months and 3 years old, scheduled for elective flexible bronchoscopy (FB) suspected positive PLS findings were enrolled.
