Yunnan Hospital "plants" ears on the patient's arm with 3D printing
On December 2, Director Wang Jihua of the Department of Plastic Surgery of the Second Affiliated Hospital of Kunming Medical College took the lead knife for the patient, and took the patient's left costal cartilage into an ear stent, which was embedded under the flap of the right forearm. After the ear on the right arm is fully grown, it will be transplanted to the damaged part by vascular anastomosis.
The operation is divided into 3 phases:
1. A skin expander is embedded in the right forearm of the patient, and the water is periodically inflated;
2. Taking the patient's autologous costal cartilage into an ear stent and embedding it under the flap of the right forearm.
3. The microsurgical vascular anastomosis technique is used to transplant the ear grown on the right forearm to the head to repair the appearance.
Car accident took away the right ear
Mr. Zhang caused severe trauma to the right maxillofacial region in a car accident a year ago, and the right auricle was avulsed. "After the car accident, I was sent to the Second Hospital of Kunming Medical College for treatment. After eight or nine operations before and after, I recovered."
Although the operation of repairing the buccal defect was successfully carried out, life was saved, but the ear that Mr. Zhang had only destroyed in the car accident could never return.
"plant" ears with 3D printing
Mr. Zhang told reporters: "When Director Wang told me that I could make an ear for me, my first reaction was just a substitute. I didn't expect it to be a real ear. Looking at this gradually forming ear, still I feel incredible."
According to Director Wang, the idea of ​​having this operation was inspired by Professor Guo Shuzhong, the world's first ear reconstruction in the First Affiliated Hospital of Xi'an Jiaotong University. "The situation of the patient is basically the same as that of Mr. Zhang," Director Wang told reporters. "The department has completed more than 300 cases of small ear deformity auricular reconstruction in the past 10 years. It has rich clinical experience, Professor Guo. Under the technical guidance, we decided to carry out the operation."
Director Wang said to the reporter, "After confirming the surgical plan, we buried a dilator in the patient's arm, and put a little water into it every day, slowly bulging a bag. This is equivalent to making a new skin, and this piece of skin To be thin, only thin enough to make the shape look good. 'Preparation' has, and opened a mouth on his left chest, took out a few costal cartilage, print through the 3D model, make the appearance of the ear, plant Into the made leather."
