Abstract
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.
RESULTS
Totally, 12 infants with laryngeal cleft were identified. This equates to a prevalence of 0.28% in all the children who underwent flexible endoscopy at our institution. Their mean age was 5.0 ± 4.9 months and mean body weight was 4.7 ± 2.3 kg. Nine (75%) infants were referred in without laryngeal cleft diagnosis, which was missed by 11 prior bronchoscopy and 5 computer tomography examinations. With the FE-NIV-SPI technique, the pharyngolaryngeal space could be pneumatically dilated permitting a detailed assessment. All laryngeal cleft types and coexisting AET lesions were visualized at the first FE-NIV-SPI examination with a mean time of 4.2 ± 0.9 min; they were eight Type I, two Type II, and one Type III. Ten (83.3%) infants had coexisting airway malacia.
CONCLUSION
Routine use of FE-NIV-SPI technique can help in early detection of laryngeal clefts and other associated AET lesions. Further multicenter collaborative investigations are essential to verify the early detection of this rare and occult lesion of the laryngeal cleft with this technique.
