35-year-old microtia can be corrected. The plastic surgery of microtia is mainly to shape the external ear by transplanting autogenous costal cartilage, so as to effectively reconstruct the contour of the external ear and reasonably transfer or cover the skin of the residual ear, thus improving the appearance of the ear. Specific surgical methods can include auricle correction, hearing reconstruction, ear implant deformity correction, costal cartilage ear deformity correction and so on. The doctor will choose the appropriate surgical method according to the severity of the patient's condition.

It should be noted that surgery is risky, so it is very important to choose an experienced doctor for treatment, so as to achieve better results and avoid adverse reactions. In addition, postoperative care and recovery are also key. Patients need to pay attention to keep local cleanliness, avoid getting wet, and adjust diet and rest according to doctor's advice.

As for the specific surgical effect and recovery time, it will be different due to individual differences and the severity of the disease. Generally speaking, it takes a period of recovery after surgery, about 60 to 90 days.
