What is scar, scar explanation!

"Scar" is the physical, biological, chemical factors, such as damage effects on human skin soft tissue, cause serious skin soft tissue damage and cannot be completely normal repair by oneself, by fibrous tissue replacement repair left that affect appearance and function of local symptoms."Scar" brings to the patient is tremendous physical pain and mental suffering, in particular, severe trauma, burn or scald after left scar.Scar hyperplasia period of a few years time almost let patients suffering.And then shrinking period and beyond recognition, dysfunction, causing great body, heart patients with double obstacles.

Scar characteristics

Skin table shows nodular hyperplasia, surface smooth, color is red and shiny, often found that expansion of the capillaries.Skin lesions juts out from the edge to crab legs deformation.Skin damage each size, shape differences, qualitative hard, such as chondroid, self-conscious symptom more feel itching discomfort or pain, burning.Because of the sharp pain, may is a sensitive nerve endings conduction or micro neuroma formation, and even clothing gently touched the feeling of pain.Develop slowly, mostly continues to increase, some scar skin glossy and surrounding tissue, with a white color slightly.Very few retraction phenomenon on its own, occasionally there are malignant.Keloid occurs in the chest, shoulders, neck, back and auricle, rarely seen in the eyelids, hand, foot plantar and external genital organs and other parts.Although the keloid is common, but its etiology hitherto unknown, which bring great difficulty to treat.How crazy proliferation inhibition of fiber cells, prevent its recurrence and continued growth has become a difficulty in today's medicine.The treatment has the following methods: surgical resection, grinding technique, laser, radiation, bureau of sealing, refrigeration, etc.A single treatment often cannot obtain satisfied effect and easy to make the site even worse.Such as surgical removal of the recurrence rate is high, the laser closed often pain, and in a variety of disease, female menstruation to be not moved, male impotence, obesity, etc.Skin grinding pin, laser, frozen, unable to prevent a relapse, this makes a lot of patients and doctors are very tricky.Many doctors even answer the patient said: "more difficult than cancer cure scar a knot in one's heart."Actually this opinion is rather one-sided.Keloid, excessive scar hyperplasia is a kind of important complication of trauma, traumatic, there are a lot of the cause of scar, such as: burns, trauma, wounds, acne (whelk), Pierce ears, vaccinations, can form different degree and keloid scar hyperplasia.Before the measures mainly depends on which it is expected to scarring, formed has yet to mature stage, main purpose is to remove all kinds of factors causing scar hyperplasia, reduce the growth of the scar, prevent scar on the body caused by a variety of deformity and dysfunction.

Scar important and dangerous

Scar is the inevitable outcome in the process of human trauma repair, broadly speaking, no scar, no wounds to heal.Scar tissue is the main component of fiber protein.Scar tissue collagen production and deposition to increase the strength of the wound, from the general meaning is beneficial.If scar tissue to form is not sufficient, damaged tissue is not normal tension, which can lead to many complications, such as abdominal incision healing of scar is weak, in under the action of internal pressure can make the scar on abdominal contents to crack or bulging outward and gradually form the abdominal wall hernia.On the contrary, if excessive scar formation, can cause serious appearance or function on the important issues.The harm of scar depends on its nature and features, and secondary fixation of deep tissue.Therefore scar relative to damage organization before, always a perfect replacement.From the mechanical point of view, its strong resistance decreased;From the Angle of nutrition, the oxygen and nutrients to communication obstacles;From a functional perspective, cause deformity and dysfunction of damaged tissue from aesthetic perspective, the appearance of the damage.
