Scar Tissue

[blueyedevil]

Why is scar tissue raised?

In my mind it would be more understandable if a scar was a dent as it was filling it in, but for it to be raised means the body put to much 'filling' wouldn't it?

Not all scar tissue is raised. There are three different types of scars --- atrophic, hypertrophic, and keloidal. Atrophic scars are depressed and cause a valley or hole in the skin. Hypertrophic scars are elevated and will subside with time. Keloids are actually non-malignant tumors formed by scar tissue that exceeds the boundaries of an original incision or injury. Keloidal scars are elevated, expansive and continue to grow. In addition to appearance, location and orientation are also important considerations in determining scar type. If a scar is thickened, does not invade normal tissue, and lies across the relaxed skin tension lines (creases in the skin), then it is a hypertrophic scar. If it is elevated and invading normal tissue, then it is a keloid scar. All types of scarring can occur on all areas of the body, but some areas such as the chest, knees and elbows are more likely to scar. (Source: Texas ENT Consultants. LLC)

E.g. Chickenpox and smallpox scars tend to be dents, not ridges.

the end result of a laceration/cut is really determined by the amount of tissue damage and the immediate repair. large or small lacerations with jagged edges repair very well with proper repair left alone they heal great but show more scaring. lacarations /incisions like plastic or corrective surgery are smooth edge but are repaired in such fine sutures that they join very well when properly cared for. when the care is proper and there is no swelling at the site scaring is almost invisible/plastic surgery. only when a hematoma/bruse, or edema to the site/swelling occures fluid pushed into the wound raises the incision and raised scar commonly occure.All in all the most occurances of edema are from trauma related injuries, damage to the site increases tissue damage/ bruises raised scars ect.
