Ear cartilage rhinoplasty is a method of nasal plastic surgery using autologous cartilage. During the operation, the doctor will extract a small piece of cartilage tissue from the patient's ear or costal cartilage and implant it in the part of the nose that needs to be raised or deformed.

Regarding dressing, generally speaking, after the operation is completed, the doctor will dress and fix the incision at the nasal cavity and ear of the patient to help the cartilage tissue heal and shape better. This process usually requires lying down for a period of time and needs the guidance and demonstration of the corresponding doctor. The specific dressing method may be different according to the doctor's personal preference and the patient's specific situation. It is recommended to consult the doctor before operation and confirm the corresponding operation steps.

It should be noted that auricular cartilage rhinoplasty is a complicated operation that requires professional doctors to operate. Therefore, before considering surgery, patients should fully understand the risks and effects of surgery and find an experienced plastic surgeon for consultation and surgery. At the same time, postoperative care should be carried out in strict accordance with the doctor's advice and guidance to ensure the best recovery of the surgical effect.
