In a hospital in Yunnan, the 3D printed shape of costal cartilage was used in the earless patients, and the ear was "planted" on the arm.
Release date: 2016-12-22
The operation is divided into 3 phases:
1. Embed a skin expander in the patient's right forearm and periodically inject water to expand;
2. Take the patient's autologous costal cartilage into an ear stent and embed it under the flap of the right forearm.
3. Apply the microsurgical vascular anastomosis technique to transplant the ears with the right forearm growth to the head to repair the appearance.
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.
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."
Complete surgery 3 months later
In the conversation, the reporter found that in fact, Mr. Zhang’s hearing was not damaged, but the lack of tissues and organs in the head and face, such as the ears, caused Mr. Zhang to have negative emotions, affecting normal work and life. This surgery allows him to recover lost confidence.
Director Wang said: "When the re-created ears grow thinner and thinner, the shape is getting better and better, I am ready to move it up." The reporter asked how long it will take, Director Wang said that it will take three months. . This external auricle reconstruction surgery belongs to the highest level of surgery in plastic surgery. The current operation is the first case in Yunnan and the second in the world.
The entire procedure is divided into 3 steps and is currently the second most difficult step to complete. The final result can only be determined after the ear has been replanted.
