Resumo(s)
O pavilhão auricular é uma estrutura sofisticada com uma arquitectura complexa. A sua frágil anatomia, a localização topográfica e a desejável simetria entre os dois pavilhões auriculares fazem com que a correcção dos seus defeitos constitua um desafio no ramo da Otorrinolaringologia e da Cirurgia Plástica Facial e obrigam a um cuidado redobrado na planificação e realização das técnicas reconstrutivas.
Existem diversas situações relacionadas a deformidades do pavilhão auricular onde é necessária reconstrução. Essas deformidades podem ser congénitas ou adquiridas, resultando em perda parcial ou total.
A reconstrução da orelha depende da sistematização das técnicas cirúrgicas e dos princípios de transferências de tecidos assim como de um bom conhecimento de design artístico.
A idade moderna da reconstrução auricular começou no século XX, com valiosas contribuições científicas que abriram alentadas perspectivas nos enfoques anatómico, artístico e estético.
As técnicas de reconstrução auricular incluem enxertos de cartilagem costal autóloga, próteses osteo-integradas e implantes aloplásticos.
Encontram-se actualmente em estudo outras técnicas de apoio à reconstrução como o modelo de impressão 3D e a engenharia de tecidos.
The auricle is a sophisticated structure with a complex architecture. Its fragile anatomy, its topographic location and the desirable symmetry between the two auricular pavilions make the correction of its defects a challenge in the field of Otorhinolaryngology and Facial Plastic Surgery and require a careful care in the planning and realization of reconstructive techniques. There are several situations related to auricular deformities where reconstruction is necessary. These deformities may be congenital, acquired or tumor related, resulting in partial or total loss. Reconstruction of the ear depends on the systematization of surgical techniques and the principles of tissue transfer as well as a good knowledge of artistic design. The modern age of auricular reconstruction began in the twentieth century with valuable scientific contributions that opened up promising perspectives in anatomical, artistic, and aesthetic approaches. Auricular reconstruction techniques include autologous costal cartilage grafts, osteointegrated prosthesis, and alloplastic implants. Other reconstruction techniques, such as the 3D printing model and tissue engineering, are currently being studied.
