microtia
Pronunciation: my-crow-TEE-ah
Congenital malformation characterized by underdevelopment of the external ear.
Full Definition
Microtia is a congenital deformity where the external ear (auricle) is underdeveloped or absent. The condition ranges from mild structural abnormalities to complete absence of the ear (anotia). Reconstruction typically requires multiple staged procedures using autologous rib cartilage or synthetic frameworks, often beginning around age 6-10 when sufficient cartilage is available. The condition frequently occurs with canal atresia, requiring coordination with otolaryngology for hearing restoration.
Usage
Usage note: Grade microtia severity using Nagata or other established classification systems.
