Postauricular skin is one of the potential donor sites for split-thickness skin grafts (STSGs).
To objectively quantify how postauricular donor sites heal after STSG harvesting.
A cohort of 39 Mohs micrographic surgery patients repaired with STSGs (total 41 surgical defects) was established. Scars resulting from postauricular donor site harvesting were objectively quantified by applying the Vancouver Scar Scale (VSS), in which healing of scars is ranked from 0 (best possible outcome) to 13 (worst possible outcome).
Vancouver Scar Scale scores were 1.87 for sites followed for ≥6 months (n = 16), 3 for sites followed for 3 to 6 months (n = 7), and 1.61 for sites followed for 6 to 11 weeks (n = 18). Four patients developed mild hypertrophic scarring that resolved spontaneously or with intralesional triamcinolone injections at a concentration of 10 mg/mL.
The postauricular skin is an excellent donor site for small-to-moderate sized STSGs (<10 cm). The donor sites healed well, as noted by the low scores on the VSS consistent with mild changes in erythema, pigmentation, and texture. The incidence of hypertrophic scarring was low and resolved with observation or treatment.
耳后皮肤是获取断层皮片（STSG）的潜在供皮区之一。
客观量化耳后供皮区在获取 STSG 后的愈合情况。
本研究纳入了 39 例接受 STSG 修复的 Mohs 显微外科手术患者（共 41 个手术缺损）。采用温哥华瘢痕量表（VSS）对耳后供皮区的瘢痕进行客观量化，VSS 评分范围从 0（最佳结果）到 13（最差结果）。
随访时间≥6 个月的 16 个部位的 VSS 评分为 1.87，随访时间 36 个月的 7 个部位的 VSS 评分为 3，随访时间 611 周的 18 个部位的 VSS 评分为 1.61。4 例患者出现轻度增生性瘢痕，可自发消退或用浓度为 10mg/mL 的曲安奈德行皮损内注射消退。
耳后皮肤是获取小至中等大小 STSG（<10cm）的理想供皮区。VSS 评分较低，表明愈合良好，仅有轻度红斑、色素沉着和纹理改变。增生性瘢痕的发生率较低，可通过观察或治疗消退。
