What is the effect on glottic gap and voice quality of medialization laryngoplasty (ML) alone versus ML with arytenoid adduction (AA) in unilateral vocal fold paralysis (UVFP) patients?
Bottom line
ML with AA, but not ML alone resulted in statistically significant improvement in PG UVFP, meaning that patients undergoing ML may benefit from AA when a large posterior glottic gap is present.
Explore this issue:
November 2017Background: Three procedures are commonly performed to permanently treat UVFP: laryngeal reinnervation, ML, and AA. There are no widely accepted indications for AA, and the need for it preoperatively or intraoperatively is determined in different ways at different institutions. There is also a debate over whether the addition of AA to ML truly improves clinical outcomes, as well as concern that adding AA increases complication rates.
Study design: Retrospective case series of UVFP patients treated with ML alone (47) and ML with AA (27) between 2011 and 2016.
