Otoplasty (prominent ear surgery), like any surgical procedure, may involve certain risks and potential side effects. These risks are generally low and considered minimal in most cases. Meticulous adherence to the doctor's instructions before the operation and careful attention to post-operative care guidelines significantly reduce potential risks. The main risks and complications associated with otoplasty may include:

* Infection: An infection may develop in the surgical area; this can usually be successfully managed with antibiotic treatment.
* Hematoma: Blood collection (hematoma) may occur under the ear or in the surrounding tissues.
* Asymmetry: A difference in symmetry between the two ears may arise during the healing process or during the operation.
* Scarring: There is a possibility of a noticeable scar remaining in the incision area. However, these scars are typically placed discreetly behind the ear, making them largely imperceptible most of the time.
* Tissue Weakening/Thinning: Weakening of cartilage tissue or thinning of the skin in the surgical area may occur.
* Suture Dehiscence: The opening of sutures may lead to an undesirable alteration in ear shape.
* Numbness: Rarely, nerve damage may result in permanent numbness in the operated area.
