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 是一种伤口愈合异常的类型,常被误认为是疤痕疙瘩,但两者并不相同。增生性疤痕的额外组织仅局限于原始伤口范围内,而疤痕疙瘩则会向伤口边界之外扩展。 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.
在愈合过程中,受伤部位通常会留下疤痕。理想情况下,疤痕应平坦、狭窄,并与肤色相匹配。感染、血流受限以及创伤等多种因素会减慢愈合速度。凸起、变黑或变紧的疤痕可能引发功能性和情感上的问题。 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) 呈红色且较厚,可能伴有瘙痒或疼痛。肥厚性病变不会超出原始伤口的边界,但可在六个月内持续增厚。肥厚性瘢痕 (hypertrophic scar) 通常在一至两年内逐渐改善,然而其外观或瘙痒程度可能导致患者困扰。若疤痕靠近关节,还可能限制关节活动。
持续性的肥厚性病变可通过注射皮质类固醇进行治疗。
○ 治疗
每隔 1 个月进行 5 至 10 次病灶内类固醇注射,可显著改善肥厚性疤痕。
#Triamcinolone intralesional injection
可以尝试激光治疗与疤痕相关的红斑,但注射曲安西龙也可以通过压平疤痕来改善红斑。
#Dye laser (e.g. V-beam)
