Surgical methods for ear reconstruction, what are the surgical methods for ear reconstruction

There are two types of whole ear reconstruction surgery: staged surgery and one-time surgery. The traditional staging method is a classic surgical method, which generally consists of three steps. The first step in surgery is to insert an auricular stent.

First, a sample of the normal auricle size on the opposite side was taken with transparencies, and then a piece of costal cartilage was cut at the 7th and 9th costal cartilage symphysis of the right rib of the patient's body, and the doctor carefully carved the auricular stent according to the shape of the sample, and then implanted the stent into the pre-designed skin flap through the ear. After 3 months, the second step of otoplasty will be performed. At this stage, the ear flap wrapped with the cartilage scaffold is lifted forward, and a medium-thick or full-thickness skin piece is implanted in the back, so that the reconstructed ear is erected, and the angle is about 60°, which is close to the unaffected side.

After surgery, the ear is filled with a support and the skin continues to be supported for 3 to 4 months after survival. After another two months, the third step of tragus and nail cavity plasty can be performed. The method is to make a tongue-shaped skin flap with the pedicle in front of the front of the ear by making an incision from the original scar of the pinna, folding and suturing it to form the tragus, and grafting the wound with a medium-thick skin piece after the tongue flap is lifted to make the earnail cavity.

At the same time, some necessary trimming is done so that the reconstructed ear surgery is successful.

It was applied in the 80s of the last century according to the national conditions at that time, and the advantage of this method is that it saves time and money, and it can be completed in only two weeks. The disadvantage is that the mastoid area** extends posteriorly and upwards due to insufficient use and has some hair, so that the reconstructed ears are thicker and have hairs on the ring rim. Later, with the improvement of people's living standards, it is rarely used.

Disposable external ear reconstruction uses the high-tech biomaterial medpor material, which is a medical high-density porous polyethylene material, which has been proven by experiments and clinical studies to be non-toxic to the human body and has good biological histocompatibility. After implantation in the human body, human blood vessels and tissues can grow into the prosthetic material, and at the same time, the strength and toughness of MEDPOR are acceptable, and it can be cut and heated, shaped and carved, which is an ideal stent material for auricular reconstruction.

Due to the selection of high-tech American biomedical material medpor, this material is an advanced and safe substitute for artificial bone tissue, it has good histocompatibility, can grow capillaries and nerves, has a good shape, and will not be infected, almost no rejection reaction. Since 1999, Dr. Wu Jianming has overcome the pinnacle academic problem of ear reconstruction, and has carried out more than 500 cases of ear reconstruction surgery with one-time ear reconstruction since 1999, all of which have achieved satisfactory results. His exquisite skills are almost unsurpassed in the world, which requires not only years of painstaking research and hard research by Professor Wu, but also years of surgical experience and profound artistic attainments in aesthetics to achieve perfect results.

Professor Wang Xiaomin: Surgical methods for ear reconstruction!

Otoplasty experts pointed out that microtia reconstruction surgery uses the characteristics of the expanded ear area, thin and enlarged area, provides a good reconstructed ear flap, uses autologous rib cartilage, cartilage scaffold according to the shape of the unaffected ear, and uses small pieces of cartilage to be superimposed on the back of the auricular stent, so that the reconstructed ear has an obvious earnail cavity, realistic shape, and strong three-dimensional auricular shape.

It is a complex and challenging task to reconstruct the pinna with complex and delicate surface structure, and there are many surgical methods, including Tanzer-Brent's staged auricular reconstruction, one-stage auricular reconstruction, mastoid area**dilated auricular reconstruction, etc.

Current surgical methods include biological scaffolds and self-rib harvesting.

There are two surgical methods for ear reconstruction:

1. Non-** dilatation method: also known as direct burial method, directly embedded into the auricular stent, and the operation is divided into 2-3 times. The advantage is that there is no need for dilation**, and the disadvantage is that a large area of skin grafting is required behind the ear, which is prone to complications such as infection, stent exposure, shrinkage, and stent deformation.

2. Expansion method: including half-package method and full-package method. In the half-pack method, the dilator is first embedded behind the ear, normal saline is injected, and then the dilator is removed and the auricular stent is implanted.

Professor Wang Xiaomin: Several mainstream methods of ear reconstruction!

What are the methods of whole ear reconstruction that we must pay attention to, and what are the answers you mentioned about the methods of whole ear reconstruction are as follows. Disease analysis: According to experts, the whole ear reconstruction surgery uses the characteristics of the expanded ear area - thin and enlarged area to provide a good reconstructed ear flap, and the whole ear reconstruction surgery uses its own cartilage tissue, which is non-toxic and harmless, and will not produce rejection reaction.

Total ear reconstruction surgery, experts introduced, surgical designThe operation is carried out in two stages. The first stage of dilator embedding is an important part of realistic shape and natural appearance; The second stage of whole auricular reconstruction, fine carving, perfect realization of full ear reconstruction. There are two kinds of implant materials:

There are two main types of materials used for whole ear reconstruction, autologous cartilage and artificial materials. In terms of the time of surgery, there are one-stage total ear reconstruction and staged total ear reconstruction. It is a complex and challenging operation to reconstruct the pinna with complex and delicate surface structure in whole ear reconstruction, and there are many surgical methods, including Tanzer-Brent's staged auricular reconstruction, one-stage auricular reconstruction, mastoid area ** dilated auricular reconstruction, etc.

Professor Wang Xiaomin: How long does it take to complete the recreation of oranges? Crack this old.

It takes about half a month to a month after ear surgery before you can fully recover, and the specific recovery time is also determined by the individual's constitution. Everyone's constitution is different, and the recovery time can vary significantly. Ear surgery can improve the shape of the ear, which can make the ear look more aesthetically pleasing and increase the overall contour of the ear.

How long will it take to get back to this? Reply, it depends on the situation, it depends on your situation, the quality of your body and the severity of your condition.

Ear reconstruction surgery can be recovered in 1-3 months, and the recovery time is different, because the basic conditions of the patient's ear are different, the ear reconstruction method that needs to be selected is different, and the degree of trauma to the ear part is also different, and the recovery time will naturally be different; In addition, the recovery time will be different for individuals with different body metabolism rates and different resistances. My child's ear reconstruction surgery at Dr. Bai Yu Kang Chunyu in Milan, Chengdu, took about 3 months to recover. I'm recovering well, and now I don't have to look at people in a strange way anymore.

About 3-4 hours; **Cycle: Hospitalization for about 1 week after each operation, divided into two phases of surgery, with an interval of 6 months; Advantages: simple method, short cycle, suitable for loose and thin customers; Cons:

Skin grafting is required behind the ear, and there will be a certain **color difference. 2. The operation time of the dilation method all-inclusive ear reconstruction surgery: about 20-30 minutes for the first operation to bury the dilator, and about 2-3 hours for the second operation; **Period:

There is a 3-4 month expansion period of water injection; Advantages: no skin graft is required behind the ear, less trauma, the contour of the ear is clear and vivid after surgery, and the color is consistent; Cons: There is an embarrassing period of months.

Commonly used ear reconstruction materials are ribs and artificial bone materials 3, biological scaffolds one-time shaping ear reconstruction surgery operation time: about 3 hours; **Cycle: One surgery, about 1 week of hospitalization after surgery; Pros:

It is suitable for children over 5 years old, weighing 30 pounds, and adults with costal cartilage calcification; Disadvantages: The material texture is hard, can not be squeezed vigorously, and is easy to wear out. My child's unilateral microtia with no obvious auricle was reconstructed by Dr. Kang Chunyu of Chengdu Milan Baiyu Hospital, which was a dilation method for all-inclusive ear reconstruction, which took a total of 5 months.
