Conclusion
Micronized acellular dermis (Cymetra) is an important material for all practitioners managing glottic insufficiency because of its overall safety and availability for immediate use. This latter point is a key advantage over bovine collagen. With the advent of other materials, such as non-donor human collagen protein (Cosmoplast, Inamed Corp., Santa Barbara, Calif.), this feature may no longer be unique. There are several technical issues with preparation that must be mastered to have predictable results. When used for vocal augmentation, the duration of clinical benefit from micronized acellular dermis is not well established scientifically. While it appears last about 3 months, this may not be true in all cases.
