Ear correction cosmetic surgery is the only procedure that can be done in childhood.  Ears finish their development around the age of 9 years and remain so all life!  So from 9-10 years a corrective surgery can be done.
This is excellent for the children who enter  into puberty without this defect and will not be subject to joke for the people around.

There are various deformities of the ear, but the most common (90%) is one in which the ears are too far from the head - ears pinning.
The surgery is performed under local anesthesia and takes between 1-2 hours, depending on complexity. Pain is absent or minimal and disappears with the usual painkillers. . Sure, your ears will be swollen and colorful these days, but once the stitches are removed, in 12 days will all disappear..
For several weeks you must wear a headband to help healing.
It is the kind of intervention that can be done once in life and its result is permanent.

Rupture may be complete or partial. The surgery is performed under local anesthesia, takes only 5 minutes without any pain..  The earring hole can remain or make others after healing.
