A hypertrophic scar is a cutaneous condition characterized by deposits of excessive amounts of collagen which gives rise to a raised scar, but not to the degree observed with keloids. Like keloids, they form most often at the sites of pimples, body piercings, cuts and burns.
Hypertrophic scarring 是一種傷口癒合時出現問題的類型。它常與疤痕疙瘩混淆,但兩者並不相同。增生性疤痕的額外組織僅在原始傷口區域內形成;相對地,疤痕疙瘩會擴散至傷口邊界之外。 Hypertrophic scarring represents an undesirable variant in the wound healing process. Another variant of wound healing, the keloid scar, is often used interchangeably with hypertrophic scarring, but this is incorrect. The excess connective tissue deposited in hypertrophic scarring is restricted to the area within the original wound. The excess connective tissue deposited in the keloid, however, extends beyond the area of the original wound.
作為癒合過程的一部分,受傷後常會留下疤痕。理想情況下,疤痕應平坦、狹窄,且與膚色相匹配。感染、血流受限、創傷等多種因素會減慢癒合速度。凸起、變黑或變緊的疤痕可能引發功能性或情緒上的問題。 Scars are a natural and normal part of healing following an injury to the integumentary system. Ideally, scars should be flat, narrow, and color-matched. Several factors can contribute to poor wound healing. These include but are not limited to infection, poor blood flow, ischemia, and trauma. Proliferative, hyperpigmented, or contracted scars can cause serious problems with both function and emotional well-being.
肥厚性瘢痕 (hypertrophic scar) 呈紅色且較厚,可能伴隨發癢或疼痛。肥厚性病灶不會超出原始傷口的邊界,但可能持續增厚長達六個月。肥厚性瘢痕 (hypertrophic scar) 通常在一至兩年內逐漸改善,然而因外觀或強烈的搔癢可能造成困擾。若疤痕位於關節附近,亦可能限制關節活動。
持續的肥厚性病變可透過注射皮質類固醇加以治療。
○ 治療
每隔 1 個月於病灶內注射類固醇 5 至 10 次,可改善肥厚性疤痕。
#Triamcinolone intralesional injection
可以嘗試雷射治療與疤痕相關的紅斑,但注射曲安西龍也可以透過壓平疤痕來改善紅斑。
#Dye laser (e.g. V-beam)
