Abstract

INTRODUCTION:

Vocal outcomes after medialization laryngoplasty are variable and may change over time. A revision procedure via open approach or an injection laryngoplasty may be necessary to improve vocal outcomes.

METHODS:

A retrospective chart review was performed.

RESULTS:

Twenty-nine subjects were identified and stratified into group 1A (n = 9) if the allograft was repositioned/replaced, group 1B (n = 4) if the allograft was removed, and group 2 (n = 16) if an injection laryngoplasty was performed. Statistically significant differences were found between all data prerevision to postrevision (P < or = 0.05) for group 1A and group 2 when multiple paired-sample t tests were calculated for patient-reported voice severity ratings and voice impact ratings as well as clinician-reported voice ratings of grade, roughness, and breathiness. Results of group 2 were often temporary, with 10 of 16 (62.5%) subjects receiving multiple injections.

CONCLUSION:

Both open revision laryngoplasty and injection laryngoplasty are successful at providing improved vocal outcomes. Results are often temporary after injection laryngoplasty and often require multiple procedures.
