Cymetra® Micronized AlloDerm® Tissue has been used in injection laryngoplasty procedures to treat vocal fold paralysis for more than 7 years1
“Cymetra injection laryngoplasty with micronized AlloDerm, a presently available homologous collagen, remains a suitable option for the treatment of vocal fold immobility with a moderate gap….Cymetra injection laryngoplasty offers improved vocal and vibratory function to patients with unilateral true vocal fold paralysis.”2

An innovative technique for injection laryngoplasty repair using Cymetra® Micronized AlloDerm® Tissue
Vocal fold injections tend to be simpler and less invasive than alternative medialization implant therapies. They are typically used when recurrent laryngeal nerve function is expected to return or when the prognosis for recovery is unknown during the first 6 months after the onset of unilateral vocal cord paralysis. Cymetra® Micronized Tissue is an attractive option for surgeons for use in injection laryngoplasty to provide structural support. Published results1,2 have shown Cymetra® Micronized Tissue to effectively medialize the vocal folds, resulting in significant voice improvement.
Injection medialization of the vocal cords has been a key application for more than ten thousand Cymetra® Micronized Tissue treatments delivered to date.
Cymetra® Micronized Tissue is processed from donated human skin supplied from U.S. tissue banks compliant with Food and Drug Administration (FDA) regulations and American Association of Tissue Bank (AATB) guidelines. Through a patented method, the allograft skin is minimally processed to remove epidermal and dermal cells while preserving an intact extracellular matrix. The resulting acellular tissue is freeze-dried using a patented process. The sheets of intact, acellular dermis are then converted into micronized particles through a process called cryofracture without damage to the matrix components.
Cymetra® Micronized Tissue is supplied as a dried, acellular particulate dermal matrix. After rehydration as directed, Cymetra® Micronized Tissue is ready for delivery by injection. Cymetra® Micronized Tissue is intended for single patient use only. Cymetra® Micronized Tissue comes in an all-in-one package that includes all the standard disposable supplies necessary to facilitate rehydration and delivery.
