By injecting fluid into the dilating capsule to increase the volume of the dilator, the pressure is generated on the skin tissue on its surface, and through the local action of the dilating mechanism, the division and proliferation of tissue and epidermal cells and the enlargement of cell gaps increase the skin area, or the mechanical traction outside the skin expands and extends the skin tissue, and the newly increased skin soft tissue is used for tissue repair and organ reconstruction.
How many procedures are required to perform soft tissue skin expansion? How long does it take?
Generally, two surgeries are required. The first surgery is for expander implantation to prepare the skin for reconstruction and addition, and the second surgery is to use the additional skin tissue to perform the desired repair. The interval between the two procedures is approximately 2-3 months.
What are the indications for soft tissue skin expansion?
1.Large facial hyperplastic or atrophic scar 2.Large pigmented nevus 3.Large capillary hemangioma 4.Traumatic tattoo 5.Neurofibroma and partially resectable skin malignant tumor 6.Repair of cavernous defect 7.Recreation of upper and lower lip, upper and lower lid, eye socket, ear, nose and other organs What are the complications of skin soft tissue expansion?
Soft tissue skin dilation requires two surgeries and 2-3 months or more of fluid injection, the main complications are infection, bleeding, and exposure of the dilator. There is a risk of pain and deformation of adjacent tissues and organs during the later stages of fluid injection.
What should be noted by patients with skin soft tissue dilation after discharge from the hospital?
1, diet: head and neck surgery after eating a warm and cool diet, other parts of the diet no special requirements. It is necessary to pay attention to nutritional matching and reasonable diet.
2, limit strenuous exercise: the first phase of surgery after discharge from the hospital, in addition to not participate in strenuous activities, general life can take care of themselves. After the removal of stitches in the first stage of surgery, the time of water injection for dilator patients should be carried out in accordance with medical advice, generally 1-3 times a week, and keep records.
3, water injection during protection: patients pay attention to protect the dilator can not have external pressure collision, and not to use sharp and hard objects in the area of buried dilator, such as wearing clothes with zipper on the chest after neck dilator surgery, and using metal type hairpin after head and face dilator. During the water injection period, patients should prevent from catching a cold to prevent the chance of dilator infection from decreasing resistance after the cold. Avoid going to public places and stay away from dangerous activity areas. Keep the local skin clean.
4, scalp dilator patients, the day of water injection, patients are not allowed to wash their hair, wash the hair gently to prevent the dilated skin breakage.
