The loss of cartilage and bone because of congential defects, trauma and after tumor resection is a major clinical problem in head and neck surgery. The most prevalent methods of tissue repair are through autologous grafting or using implants. Tissue engineering applies the principles of engineering and life sciences in order to create bioartificial cartilage and bone. Most strategies for cartilage tissue engineering are based on resorbable biomaterials as temporary scaffolds for chondrocytes or precursor cells. Clinical application of tissue-engineered cartilage for reconstructive head and neck surgery as opposed to orthopedic applications has not been well established. While in orthopedic and trauma surgery engineered constructs or autologous chondrocytes are placed in the immunoprivileged region of joints, the subcutaneous transplant site in the head and neck can lead to strong inflammatory reactions and resorption of the bioartificial cartilage. Encapsulation of the engineered cartilage and modulation of the local immune response are potential strategies to overcome these limitations. In bone tissue engineering the combination of osteoconductive matrices, osteoinductive proteins such as bone morphogenetic proteins and osteogenic progenitor cells from the bone marrow or osteoblasts from bone biopsies offer a variety of tools for bone reconstruction in the craniofacial area. The utility of each technique is site dependent. Osteoconductive approaches are limited in that they merely create a favorable environment for bone formation, but do not play an active role in the recruitment of cells to the defect. Delivery of inductive signals from a scaffold can incite cells to migrate into a defect and control the progression of bone formation. Rapid osteoid matrix production in the defect site is best accomplished by using osteoblasts or progenitor cells.
