Efficacy and Complications of Interarytenoid Injection for Dysphagia in Infants 1-Year-Old and Under

The objective of this study was to assess the efficacy and complication rates of interarytenoid injection augmentation (IAIA) for the treatment of dysphagia in patients 1 year of age and under and to determine if concurrent feeding therapy (FT) affects outcome. Retrospective case series. Tertiary pediatric hospital. Retrospective review of patients 13 months of age and younger with dysphagia treated by IAIA over a 4-year period. The efficacy of IAIA was determined by comparing perioperative videofluoroscopic swallow studies (VFSS) and Dysphagia Outcome and Severity Scale (DOSS) scores. Complication rates and utilization of concomitant FT were determined by evaluating postoperative admission and follow-up records. Sixty-five patients met inclusion criteria (median age 8 months, interquartile range [IQR]: 7-11). Sixty-seven percent of patients improved on postoperative VFSS scores (median improvement in aspiration of 2 thickness levels, IQR 0-3, P
