Ear Reconstruction (Microtia)
Microtia repair has advanced and now offers single-stage or multi-stage approaches tailored to patient’s needs. The gold standard is autologous reconstruction, in which a new ear is sculped from the patient’s own rib cartilage and precisely implanted beneath a thin skin flap behind the ear to achieve the most natural appearance and feel. Recent technical improvements have made single-stage reconstruction for lobule-type microtia faster and safer, providing high satisfaction and low risk of complications. In other approaches, synthetic frameworks such as Medpor or prosthetics may be used when autologous cartilage is unsuitable. Follow-up procedures can refine the earlobe shape, deepen the conchal bowl, and improve the appearance of the tragus. The multidisciplinary support also assesses patients’ hearing needs and may place bone-anchored hearing aids during surgery to provide comprehensive rehabilitation.
Understanding Microtia
Microtia is a congenital condition in which the external ear is underdeveloped or absent. It may affect one or both ears and is often associated with hearing loss caused by atresia or stenosis of the ear canal.
Comprehensive Care at AMC
At Asan Medical Center, we provide world-class, multidisciplinary care for both children and adults with microtia. Our team of plastic and reconstructive surgeons collaborates closely with otorhinolaryngologists, audiologists, and pediatric specialists to offer individualized treatment plans that restore both form and function.
Surgical Techniques We Offer
Autologous Rib Cartilage Reconstruction
This gold-standard approach uses the patient’s own rib cartilage to create a natural-looking ear. The procedure is typically performed in multiple stages, starting around ages 8 to 10, to ensure long-term durability and optimal cosmetic results.
Medpor Implant-Based Reconstruction
For patients seeking an alternative to rib cartilage harvesting, we offer ear reconstruction using a Medpor (porous polyethylene) framework. This method allows for earlier surgery and is often completed in fewer stages.
Prosthetic Ear Reconstruction
When surgery is not advisable, we coordinate with expert prosthetists to provide custom-made, lifelike auricular prostheses tailored to each patient’s needs.
Optimal Timing for Surgery
We recommend beginning surgical reconstruction around age 8 or older, when sufficient rib cartilage is available and the child is emotionally ready. Each case is carefully evaluated to determine the most appropriate timing and technique.
