Constricted ear deformity
The extent of this deformity can vary. This is a deformity where the skin and cartilage of the helical rim and the scapha are underdeveloped. The abnormalities mentioned before are deformities, where all anatomical parts of the ear are present but not formed correctly. This is an ear malformation, which means that part of the cartilage or skin has not formed at all: anatomical parts of the ear are missing. Treatment of these ear deformities is the most challenging.
Microtia and anotia
These are ear deformities whereby the external ear is not fully developed or not developed at all. The most severe form is anotia, where the ear is absent altogether. In microtia or anotia, the ear is reconstructed in stages when the child is older.
