Introduction
In general, diagnostic methods for hypertrophic scars include physical examination, rigid dermoscopy, dermoscopic examination, three-dimensional skin CT scan, and histopathological examination. If experiencing any discomfort symptoms, patients should seek medical attention promptly and undergo relevant examinations as directed by a physician, followed by targeted treatment. Additionally, proper sun protection measures should be taken to avoid ultraviolet radiation exposure.
Generally, hypertrophic scars can be diagnosed through physical examination, dermal elasticity test, dermoscopy, three-dimensional skin CT scan, and histopathological examination. If there are any discomfort symptoms, medical attention is required. The specific analysis is as follows:
1. Physical Examination
Physical examination mainly involves observing the morphology, size, and number of scars. Additionally, the nature of the skin lesions can help determine whether it is a hypertrophic scar.
2. Dermal Elasticity Test
The dermal elasticity test primarily involves applying pressure around the skin and then releasing it shortly afterward to observe the skin's recovery, thereby assessing whether the skin maintains a certain thickness and elasticity during the healing process. This test is commonly used for the preliminary diagnosis of hypertrophic scars.
3. Dermoscopy
Dermoscopy is a type of imaging examination that can magnify the skin surface several times through an endoscope, aiding physicians in observing the specific structure of scar tissue and assisting in scar diagnosis.
4. Three-Dimensional Skin CT Scan
A three-dimensional skin CT scan can distinguish the exact condition of skin lesions, providing information about the precise depth and structure of the scar. This helps analyze the severity of the scar and whether other discomforts are present.
5. Histopathological Examination
If the above methods cannot confirm the diagnosis, analysis through pathological sectioning can also be performed. This allows observation of whether there are additional extracellular matrix components, such as fibroblasts, collagen proteins, and matrix components within the scar tissue.
If you suspect you have a hypertrophic scar, it is recommended to undergo the above examinations promptly under a doctor's guidance for timely, targeted treatment based on the results. Additionally, during periods of scar formation, proper sun protection should be practiced to avoid early exposure to ultraviolet light.
