People who have experienced microtia correction surgery should know that there are currently two commonly used ear reconstruction surgeries: expansion method and direct burial method. However, it is often difficult to choose between the two, and one does not know which surgical method is better. Today I will tell you about the expansion of Faler and its reconstruction.
What is dilation and reconstruction?
Expanded ear reconstruction uses skin expansion technology, which is a commonly used repair method in plastic surgery. The principle is to implant a skin soft tissue expander under the normal skin around the lesion, and regularly inject physiological saline into the expander to expand the surrounding skin tissue. Increased volume. This can expand the skin area and encourage cells to proliferate and to divide, thereby obtaining additional skin.
Skin expansion technology is applied to the correction of microtia. The surgical process is to bury an expander in the mastoid area behind the residual ear, and regularly inject water into it. When the expander expands, the ear skin will be stretched, and the expanded skin will It will be the skin of the "new" ear. In the second-stage surgery, the expander can be removed, the cartilage ear stent can be implanted into the expanded skin cavity, and negative pressure suction can reveal the auricle structure. How long does it take to fill
with water for expansion?
Under normal circumstances, the skin expansion time is no less than 3 months, and the amount of water injected is about 70-80ml. Inject water 1-2 times a week, with a volume of 1ml-5ml each time. Inject water according to the doctor's recommendations. You should not feel excessive swelling and pain when injecting water. If skin swelling and pain occur, stop injecting water immediately.
How many stages of surgery does the dilation method require?
In the past, many places performed three-stage surgery, but in fact, two-stage surgery can be completed. The first-stage surgery is to embed the expander, inject water, and expand the skin, which takes 4-6 months; the second-stage surgery is to remove the expander, carve a cartilage ear stent with a base, and implant it into the expanded skin. In the second-stage surgery, there is an obvious cranio-auricular angle, and the reconstructed auricle is a three-dimensional structure.
The skin expanded by the expansion method is thinner. The skin of the ears will not be very thick after the operation, and the shape of the ears will be better. The best age for surgery is 6-15 years old. In children, the skin is more elastic and easier to expand. In addition, when students are students, they do not have many requirements and concerns about their image in the workplace. However, many adult patients with microtia will also choose the expansion method. Reengineering is a good option.
Of course, whether it is the expansion method or the direct burial method, each has its own advantages. The most essential thing everyone wants is to restore the "shape" of the ear so that the overall appearance does not look so strange. You can do your homework first and then combine it with the doctor's advice. It is recommended to make a choice.
