Purpose Of Review: One of the greatest challenges in facial plastic surgery is total auricular reconstruction. The ability to construct a fully satisfactory complete external ear has for centuries been an elusive goal. With advancing standards and expectations in plastic surgery, greater focus is being directed to this arena of reconstruction as well.
Recent Findings: With advances both in surgical technique and biotechnology, an expanding range of options is available to the reconstructive surgeon who is willing to take on this still formidable task. While progress continues to be made in the detailing of costal cartilage grafts and soft-tissue rearrangement, it is also being made with the use of alloplastic implants and prostheses. The most promising field of advances, with the hope of eventual clinical utility, lies in the realm of bioengineering with cultured cartilage.
Summary: Review of the literature over the past year reveals several reports describing advances made in the development of cultured chondrocytes with attempts to direct special shape to the manufactured neocartilage. Though advances continue to be made, actual clinical applicability of this technology is still insufficient while expectation continues that this will eventually become integral to total auricular reconstruction.

Objectives: To assess the use of occipital vessels for microvascular anastomosis in head and neck free tissue transfer reconstruction.
Methods: A literature search was undertaken to identify studies utilizing the occipital vessels for microvascular anastomosis in free tissue transfer. Following literature review, 30 anatomic cadaveric dissections on 15 fresh unfixed cadavers were performed to evaluate the occipital artery and identify a reliable vein within reasonable proximity.

Microtia profoundly affects patients' appearance and psychological well-being. Tissue engineering ear cartilage scaffolds have emerged as the most promising solution for ear reconstruction. However, constructing tissue engineering ear cartilage scaffolds requires multiple passaging of chondrocytes, resulting in their dedifferentiation and loss of their special phenotypes and functions.

Traditionally, burn reconstructions have been performed by the use of skin grafting or local flaps. Recently free flaps are being used with increasing frequency. Although not very common in the head neck region, free flaps are mostly used for secondary reconstructions of cervicofacial contractures.

The demand for cartilage reconstruction in the head and neck region arises frequently due to trauma, malignancies, and hereditary diseases. Traditional tissue engineering produces cartilage from a small biopsy by combining biomaterials and expanded cells. However, this top-down approach is associated with several limitations, including the non-uniform distribution of cells, lack of physiological cell-cell and cell-matrix interactions, and compromised mechanical properties and tissue architecture.

Objective: For full expansion of ear reconstruction, the stability of a cartilage framework is very important. However, most techniques for framework fabrication focus on three-dimensional structure and adequate projection. Few studies are available on improving the stability of the reconstructed framework.
