What Is Ear Reconstruction Surgery for Microtia?

Ear reconstruction is one of the most rewarding surgeries in craniofacial care. Here is what families should know.

Ear reconstruction surgery creates a new external ear for children born with microtia. The two main approaches are rib graft reconstruction and Medpor implant.

Rib graft reconstruction (autologous):

  • Stage 1 (age 6–10):
  • Cartilage is harvested from the child's rib cage (one side)
  • The cartilage is carved into the shape of an ear
  • It is placed under the skin on the affected side
  • The child stays in the hospital 3–5 days
  • Stage 2 (4–6 months later):
  • The ear is lifted away from the head
  • A skin graft is placed behind the ear
  • This creates the natural ear fold
  • Stage 3 (optional, for lobe creation):
  • The earlobe is created or moved into position
  • Advantages:
  • Living tissue (feels natural, grows with the child)
  • No foreign body
  • Very durable (strong enough for sports)
  • Lifelong result
  • Disadvantages:
  • Requires rib harvest (chest scar)
  • 2–3 separate surgeries
  • Cannot be done before age 6

Medpor implant:

  • A synthetic ear-shaped implant is placed under the skin
  • Usually a single surgery
  • Can be done at age 3–5
  • No rib harvest needed
  • Advantages:
  • Starting age is younger
  • Single surgery
  • No chest scar
  • Disadvantages:
  • Synthetic material (risk of exposure or infection)
  • Less natural feel
  • Not as durable as rib cartilage

Clinical Guidance

Ear reconstruction for microtia is performed using either rib cartilage (autologous) or a synthetic Medpor implant. Rib graft reconstruction uses the child's own tissue and is very durable but requires multiple surgeries. Medpor is a single-surgery option but uses synthetic material.
