Abstract

Introduction: Laryngotracheoesophageal clefts (LTEC) are aspiration-related lesions often assessed using swallow studies and symptoms like respiratory or feeding difficulties. However, these indicators are unreliable predictors of disease severity. Lung inflammation and injury, though significant concerns, are rarely and inconsistently evaluated or reported. As a result, the correlation between swallow study findings and actual pulmonary disease remains unclear.

Methods: A retrospective cohort of children with LTEC seen in our Aerodigestive Program between October 1, 2012, and September 30, 2023, who underwent videofluoroscopic swallow study (VFSS) or flexible endoscopic evaluation of swallowing (FEES) were included. Data collected included clinical history, risk factors, BAL, chest CT, impedance probe, VFSS/FEES findings, and FOIS-P/I scores at baseline and follow-up.

Results: Eight-two subjects identified. Lung inflammation and bronchiectasis were common and correlated. Clinical factors, impedance probe, and the presence/severity of swallowing abnormalities on VFSS/FEES were not predictive of lung disease. Fifty-seven patients underwent LTEC repair for a range of indications, only 49% based on CT and/or BAL findings. Of 57 children who had LTEC repair, only 49% were based on CT or BAL findings. LTEC repair was associated with modest improvement feeding and swallowing.

Discussion: Children with LTEC have a high prevalence of inflammatory lung disease and injury and undergo repair for a variety of reasons. Swallow studies detect functional swallowing issues but do not reliably identify lung disease. Despite this limitation, LTEC repair is linked to improved feeding and swallowing in some patients, though not all benefit.

Keywords: bronchiectasis; bronchoalveolar lavage; flexible endoscopic evaluation of swallowing; laryngeal cleft; videoflouroscopic swallow study.
