Microtia and aural atresia are congenital deformities affecting the external ear and ear canal, often leading to both cosmetic concerns and conductive hearing loss. Surgical management aims to restore both function and aesthetics through canal-tympanoplasty for hearing rehabilitation and auricular reconstruction for external ear restoration. Canal-tympanoplasty involves the creation of an ear canal and tympanic membrane to improve sound conduction, while auricular reconstruction utilizes autologous cartilage or synthetic materials to achieve a natural ear contour. Advances in surgical techniques, including staged procedures and 3d modeling, have improved outcomes in both hearing restoration and cosmetic appearance. This review discusses current approaches, surgical considerations, and long-term outcomes in the management of microtia and atresia.
