Microtia surgery of bilateral ears performed for young boy from Tirupati

After general anesthesia, rib grafts were first harvested. Grafts obtained were from the fourth, fifth and sixth ribs. A Valsalva maneuver was then performed. This was to rule out accidental perforation into the thoracic cavity. Using a metal template, the sixth rib graft was first carved and sculpted to form the external ear framework. This was done for both the right and the left sides. The other graft pieces were then fixed and secured with nonresorbable sutures. Care was taken to maintain symmetry between the frameworks of both ears.

The skin of the right ear was first incised and underlying tissues dissected to create a pocket. The framework of ribs was then tunneled into the pocket. Skin was then sutured and surgical drain placed at the site. This step will help adapt the skin to the cartilage framework. The left ear was then addressed.

Second stage repair will be after about 3 months. This will be for elevation of the framework inserted in the first stage.
