Microtia (congenitally absent ears)
What is microtia?
Microtia is a congenital defect of the external ear.
Who does it affect?
This condition occurs 1 in 7000 – 8000 births. There is a male to female ratio of 2:1. It more commonly affects the right side of the face (ratio of right : left : bilateral = 5:3:1 ). It is more common in Asians than Caucacians
Ear Reconstruction (Nagata Technique)
Procedure: Reconstruction of the external ear using the Nagata Technique involves 2 stages:
1st stage procedure
1) Harvesting of the rib cartilages on the same side as the absent ear
2) Creating a 3-D framework out of the harvested cartilages
3) Implanting the 3-D framework into the site of the missing ear
2nd stage procedure (6 months after 1st stage procedure)
Involves lifting the reconstructed ear off the side of the scalp
Recovery Time:
2 – 4 weeks
