The study of expanded tri-lobed flap in a rabbit model: possible flap model in ear reconstruction?
BMC surgery, 2003
Local flaps are widely used in reconstructive surgery. Tri-lobed skin flap is a relatively new flap and there has been no experimental model of this flap. This flap can be used for repair of full thickness defects in the face, ears and alar region. Based on the size of ears in a rabbit, we designed a model of ear reconstruction using expanded tri-lobed flap. Local flaps are more advantageous in that they provide excellent color and texture matching up with those of the face, adequately restore ear contour, place scars in a favorable location and ideally accomplish these goals in a single stage with minimal donor site morbidity. Eight adult New Zealand rabbits were divided into two groups. 50 ml round tissue expander were implanted to four rabbits. After completion of the expansion, a superiorly based tri-lobed flap was elevated and a new ear was created from the superior dorsal skin of each rabbit. Scintigraphy with Technetium-99m pertecnetate was performed to evaluate flap viabilit...

External ear reconstruction is a controversial topic in reconstructive plastic surgery. Here, we prepared a pedicled biosynthetic flap for full-thickness, partial ear defects in rabbits. We operated on six adult female New Zealand rabbits weighing 3-4 kg. The dimensions of the lateral thoracic fasciocutaneous flap were 7 9 6 cm. The flap was elevated based on one of the bilaterally located internal thoracic arteries, which were dissected proximally. The pedicled flap was folded in two, and polypropylene mesh was sandwiched in the middle. The flap was adapted to a defect of 3.5 9 3 cm in diameter. In fact, the defect was created before elevation of the flap. Rabbits were followed up for 4 weeks, at the end of which they were killed and their ears were evaluated histopathologically. The survival rate of the rabbits was 100 %. All pedicled biosynthetic flaps were viable, but one showed partial (20 %) necrosis (1/6) and one was partially detached (1/6). Macroscopic (color, thickness, texture) and histological (polymorphonuclear leukocyte invasion in the skin, subcutaneous tissue, and at the junction between the polypropylene mesh and the flap) features of the flap were compared to the ipsilateral ear. A new technique was developed for partial external ear reconstruction with sufficient inner skeletal support and outer skin lining. Level of evidence Level NA
Restoration of Ear Defects by Prefabricated Radial Forearm Flap
Plastic and Reconstructive Surgery - Global Open, 2020
Summary: The case report involved a 36-year-old man. He was injured in a road traffic accident and had extensive third- and fourth-degree facial burns over the right side of his face, with complete loss of his right auricle. We performed a free flap coverage of the right face with the anterolateral thigh (ALT) flap. The reconstruction of his auricle was performed by culturing a cartilage framework on the forearm and transferring it straight to the original location to rebuild the new ear as free flap. Results were assessed 12 months after surgery. The follow-up is still short, but the patient is satisfied with the results achieved.

Frameworks for total ear reconstruction: past, present and future directions
Journal of 3D Printing in Medicine
Total ear reconstruction describes surgical approaches aimed toward restoring the external ear to correct acquired or congenital deformities. Frameworks for auricular reconstruction have undergone substantial evolution over the past century and are broadly categorized as either autologous or alloplastic in nature. Recently, advances in tissue engineering, regenerative medicine and materials science have opened new avenues for recreating the cartilaginous and soft tissue structures of the ear through development of cutting-edge 3D constructs derived from a patient's own cells in a process known as bioprinting. This review outlines the historical approaches to frameworks for ear reconstruction and provides an updated synopsis and appraisal of current bioprinting efforts.
