Why do keloid and hypertrophic scars form?
OCCUR DURING THE HEALING PROCESS BECAUSE COLLAGEN PRODUCTION GREATLY EXCEEDS COLLAGEN LYSIS
This kind of scar is raised, but remains within the borders of the original injury?
HYPERTROPHIC SCAR
This kind of scar extends beyond the original boundaries of an injury and damages healthy tissue?
KELOID SCAR
Describe the maturation phase?
*BEGINS APPROXIMATELY DAY NINE AND IS ONGOING
*THIS PHASE IS THE LONGEST IN DURATION; CAN LAST OVER ONE YEAR
*PROGRESSION TOWARDS RESTORATION OF THE PRIOR FUNCTION OF THE INJURED TISSUES
*COLLAGEN SYNTHESIS AND LYSIS
*COLLAGEN FIBER ORIENTATION
This phase is the longest in duration and can last for over one year?
MATURATION PHASE
Begins at approximately day nine and is ongoing?
MATURATION PHASE
Describe the proliferation phase?
*LASTS FROM DAY THREE THROUGH DAY 20
*INVOLVES CONNECTIVE TISSUES AND EPITHELIAL CELLS
*EPITHELIALIZATION, COLLAGEN PRODUCTION, WOUND, CONTRACTURE, AND NEUROVASCULARIZATION OCCUR
When does the proliferation phase begin and end?
DAYS 3-20
Stages of tissue healing?
*INFLAMMATION PHASE
*PROLIFERATION PHASE
*MATURATION PHASE
Process of the inflammation phase?
*LASTS ONE TO SIX DAYS
*OCCURS SECONDARY TO TRAUMA OR DISEASE
*PRESENTS WITH CALOR, RUBOR, TUMOR, DOLOR
*CLOT FORMATION AND PHAGOCYTOSIS OCCURS
What is the third stage of tissue healing?
MATURATION PHASE
What is the second stage of healing?
PROLIFERATION PHASE
What is the first stage of tissue healing?
INFLAMMATION PHASE
