The StemDisc is derived from the amniotic membrane and is used as a guiding matrix for regeneration of soft tissues. Amniotic tissue is often called natural bandage due to its proregenerative and anti-inflammatory characteristics and therefore well suited in inflammatory mastoid region and -middle ear.
In conjunction with the MyringoPatch or autologous tissue
The MyringoPatch is derived from fascia lata and is used as a guiding matrix for the regeneration of soft tissues. The fascia lata is thinned to mimic the thickness of the tympanic membrane. While the graft is mechenically strong and therefore suturable it also maintains it shape and does not shrink during the healing process.

Allograft tissue is gaining ground in the medical concourse for good reasons. The use of donor tissue prevents a second incision and thus reducing discomfort for the patient and donor-site morbidity. While the decellularization process ensures that the immunogenicity of the transplant is reduced to a minimum. While adverse reactions are optimally reduced, the nature of allograft provides high biocompatibility and contributes to the optimal regeneration of tissues.
