Unilateral Vocal Fold Paralysis With Large Posterior Glottic Gap: Is Arytenoid Procedure Necessary?

In patients with UVFP and large posterior glottic gap, ML + AA and ML + AApexy seem to do better subjectively and objectively, acoustically and aerodynamically, when compared to ML using prosthesis with and without large posterior extension. ML alone does not appear to close posterior glottic gap. Therefore, it is a better and more reasonable option to perform arytenoid procedure when there is large posterior glottic gap in UVFP.
