PURPOSE: The primary objective of this study was to assess the impact of EPCS/RG on swallowing function using Dysphagia Outcome and Severity Scale (DOSS) scores. Secondary objectives included decannulation rates, voice changes, and breathing improvements assessed by Empey index. METHODS: This retrospective study included patients who underwent EPCS/RG between 2017 and 2024. Patient demographics, pre- and post-procedure swallowing capacity (DOSS), tracheostomy status, and pulmonary function were extracted from medical records. Statistical analysis included Fisher exact test, Mann-Whitney-U test and Spearman's correlation. RESULTS: A total of 23 patients were included. The mean age was 9 years, with 68% being male. The median DOSS score changed insignificantly from 7 pre-op to 6 post-op (p = 0.8087), while Empey index significantly improved (p = 0.022). CONCLUSION: EPCS/RG did not significantly affect swallowing capacity but improved pulmonary function and increased decannulation rates.
