Definition - What does Antihelical Fold mean?
An antihelical fold is the cartilage in the inner ear that curves slightly. This part of the ear can be easily seen in a healthy human ear, but it can vary considerably in shape and size. While it does not impact the hearing, it can impact the overall shape of the ear.
TheConsultation explains Antihelical Fold
The absence of an antihelical fold can sometimes cause the ears to protrude slightly or severely. If this occurs, some people opt to undergo ear surgery in which the ears are pinned closer to the head and face. While the antihelical fold doesn't impact the development of hearing, the absence of it can impact a person's emotional state and lead to confidence issues. Therefore, the correction of it is considered purely cosmetic rather than a medical need.
