- Abstract
Objectives/Hypothesis: To determine the utility of preoperative penetration‐aspiration scale (PAS) scores and clinical findings on modified barium swallow (MBS) in predicting advancement of diet after interarytenoid injection augmentation (IAIA). Study Design: Retrospective review. Methods: In this retrospective cohort study, 372 consecutive patients who underwent IAIA for pharyngeal dysphagia between 2009 and 2019 were initially identified. Patients were excluded from the study if they had insufficient preop MBS, no postop MBS within 3 months of injection, supraglottoplasty, or underlying neurological condition. Ninety‐three patients were included in the study. Pre‐ and postoperative PAS scores were recorded, as were pre and postop diets. PAS scores were calculated by a single pediatric speech and language pathologist. Results: Average PAS score on MBS was 5.87 (standard deviation [SD] 2.74); median (range) = 8 (1–8). Postop average was 4.29 (SD 3.02); median (range) = 2 (1–8), P <.001. Those with worse preop PAS scores had increased odds of improvement in diet (odds ratio 1.24, 95% confidence interval [CI] 1.02–1.49, P =.029). An improvement in PAS score of 3.0 or greater predicted an improvement in diet with a sensitivity of 76.7% and a specificity of 85.7%. Conclusions: PAS score on MBS can be a useful tool when assessing pediatric patients who may be candidates for IAIA. Prospectively comparing PAS score in patients post‐IAIA to patients solely undergoing diet modification can help to better objectively assess differences in outcomes and understand the full utility of PAS score.
