The Laryngoscope

Micronized Alloderm (Cymetra) is a relatively new product used for vocal fold augmentation. Previous studies evaluating possible long-term effectiveness of this product have shown mixed results. The objective of this present study is to reassess possible long-term results of Cymetra injection laryngoplasty in patients with unilateral true vocal fold paralysis. ⋯ Cymetra injection laryngoplasty offers improved vocal and vibratory function to patients with unilateral true vocal fold paralysis. The benefits of such medialization may be longer lasting than previously reported, and further long-term study is warranted.
