Abstract
Background Injection medialization is performed to improve glottic closure, thereby airway protection. Overall objective to determine if unilateral injection medialization changes glottal area with concomitant adjustments in penetration/aspiration scale (PAS) scores and pharyngeal high-resolution manometry (HRM) parameters. Methods Enrolled 17 adults with unilateral vocal fold paralysis/paresis and aspiration/penetration. Fiberoptic endoscopic evaluation of swallowing and pharyngeal HRM completed at (1) baseline (within 1 week before injection), (2) postinjection (within 1 week post injection), and (3) 1-month postinjection. Comparisons between time points for PAS scores, glottal area, pharyngeal pressure, and timing. Results No significant differences in normalized glottal area. No significant differences in PAS scores, for any consistency. Significantly increased rate of mesopharynx pressure rise and maximum pressure at 1 month postinjection (P = .01 and .02, respectively) compared to baseline. Significant decrease in mesopharynx integral from baseline to 1 week postoperative (P = .03). Conclusion Findings suggest unilateral vocal fold injection medialization had limited effect on swallow function.
