A congenital disorder (present at birth) or a trauma or cancer surgery can cause an ear to become misshapen or missing, requiring ear reconstruction. Reconstruction of the ear can be performed in several ways. In these cases, the patient's cartilage may be used (autologous), an implant, or a prosthetic implant.
Microtia means the ear is very small, malformed, or absent and caused by a congenital condition. Genetic abnormalities may cause some ear deformities, also associated with other congenital disorders.
In otoplasty, the outer, visible parts of the ear are surgically altered. An ear pinning, for example, can surgically angle the ears closer to the head to reduce their prominence.
Plastic surgery can be necessary to restore the form and function of the outer ear after trauma or cancer surgery.
