EAR RECONSTRUCTION | MICROTIA SURGERY
What is ear reconstruction?
Autologous ear reconstruction using rib cartilage
Autologous ear reconstruction requires multiple surgical stages. During the initial stage, cartilage is taken from the ribs and used to create a three-dimensional sculpture that looks like a normal ear. This is the technique used by most surgeons, and is typically performed when the patient is between 6 and 10 years of age. At this age, the opposite ear is close to adult size and the ribs will provide enough material to create a framework of adequate size.
The cartilage framework is then placed under the skin at the site of the newly placed ear, to match the opposite ear. Additional cartilage may be saved either at the rib donor site or underneath the temporal scalp for use in a later stage. Suction catheters are placed under the skin to create better definition around the framework. They are removed in one to two weeks. Children are usually admitted to the hospital for three to five days.
Several techniques have been adopted for autologous ear reconstruction, i.e. the Brent method and the Nagata method. The differences in these techniques lie in the number of stages required for ear reconstruction (between 2 and 4) and the amount of cartilage needed to make the ear framework. For the Nagata method, children should be closer to 10 years of age to make sure there is enough cartilage to take from the ribs.
