Abstract
A tympano-ossicular tissue bank complying with European Union regulations on human allografts is feasible and critical to assure that the patient receives tissue which is safe, individually checked and prepared in a suitable environment. The transcranial procurement technique has become the standard approach to procure tympano-ossicular allografts since the 1970s because it can provide en bloc allografts. Over the last 1020 years, en bloc allografts have been abandoned and only the malleus (hammer) is left attached to the tympanic membrane. This modification enables introduction of the transmeatal procurement technique. Transmeatal procurement using readily available nasal 0° and 30° endoscopes is a feasible alternative which avoids contact with the dura mater and is not esthetically invasive to the donor. It involves a more time-consuming procurement but avoids the need for preparation of the temporal bone plug and is therefore generally more time-efficient.
