The application of tissue engineering procedures to repair the larynx.

The field of tissue engineering/regenerative medicine combines the quantitative principles of engineering with the principles of the life sciences toward the goal of reconstituting structurally and functionally normal tissues and organs. There has been relatively little application of tissue engineering efforts toward the organs of speech, voice, and hearing. The present manuscript describes a study that was conducted in which a biologic scaffold derived from porcine (pig) extracellular matrix (ECM) was used to repair the defect following a hemilaryngectomy procedure in dogs.
