The pinna, or outer ear structure, varies uniquely for each individual. When reconstructing the ear surgically, Dr. Panossian utilizes either the patient's cartilage or MEDPOR porous polyethylene, skillfully shaping them with specialized surgical tools. In microtia cases where one ear is affected, and the other remains normal, Dr. Panossian can use the unaffected ear as a reference to create a closely matched replica. It's important to note that pediatric and adult ear sizes may require different surgical techniques to achieve optimal results.
