溫哥華疤痕評量尺計分標準表修改版(MVSS)
Modified Vancouver Scar Scale(MVSS)1:
Score | Pigmentation | Vascularity | Pliability | Height | Pain and Itchiness |
0 | Normal | Normal | Normal | Flat | None |
1 | Hypopigmented | Pink | Supple | < 2mm | Occasional |
2 | Mixed | Red | Yielding | 2-5mm | Requires medication |
3 | Hyperpigmented | Purple | Firm | > 5mm | |
4 | Ropes | ||||
5 | Contracture |
Baryza把VSS的色澤評估增加一級,讓除了柔軟度5級外,其他都為3級,並另外增加痛及癢兩項主觀評估。
Vancouver Scar Scale疤痕測量尺的Baryza修改版:
在2000年,Nedelce B又修改了VSS,將柔軟度簡化為4級,但將疤痕高度細分成4級2,總分仍為14分,並再加上痛及癢的主觀評估。
Vancouver Scar Scale疤痕測量尺的Nedelce修改版:
*Pain and itching are also assessed and documented usually using the 0-10 scale
關於這個modified version of the Vancouver Scar Scale,Forbes-Duchart於2007年發表一篇研究,結論是當評估燒傷疤痕的治療結果時,只有MVSS的總分能被採信,而個別項目評分的信度是很低的3,因此當某個洋蔥除疤產品根據某項研究宣稱其雖無法降低疤痕高度及柔軟度,但是可以淡疤時,我們可能需要重新思考其所代表的意義。

溫哥華疤痕評量尺(Vancouver scar scale,VSS)
游朝慶
溫哥華疤痕評量尺(Vancouver scar scale,VSS)是由加拿大溫哥華總醫院燒傷中心的Sullivan於1990年發表出來1,或許是世界上最廣為熟知的燒傷疤痕評估系統,又被公認為Burn Scar Index。其採用色澤(Pigmentation)、厚度(height)、血管分佈(vascularity)、柔軟度(pliability)四個指標對疤痕進行描述性評價,評分標準如下:
Pliability柔軟度 | 0 | Normal |
| 1 | Supple柔軟的(在最少阻力下皮膚能變形的)Supple, flexible with minimal resistance) |
| 2 | Yielding有彈性的,柔順的(在壓力下能變形的)(giving way to pressure, offering moderate resistance but does not behave as a solid mass of scar) |
| 3 | Firm結實的,硬的(不能變形的,移動呈塊狀,對壓力有阻力(solid, inflexible unit, not easily moved, resistant to manual pressure) |
| 4 | Banding彎曲(組織如繩狀,瘢痕伸展時會退縮)(rope-like tissue that blanches with extension of scar, does not limit ROM) |
| 5 | Contracture攣縮(瘢痕永久性短縮導致殘廢與扭曲)(permanent shortening of the scar producing deformity or distortion, limits ROM) |
Height厚度 | 0 | Normal |
| 1 | <2 mm |
| 2 | 2-5 mm |
| 3 | >5 mm |
Vascularity血管分布 | 0 | Normal瘢痕膚色和身體正常部位近似 |
(redness) | 1 | Pink膚色偏粉紅(slight increase in local blood supply) |
| 2 | Red膚色偏紅(significant increase in local blood supply) |
| 3 | Purple膚色呈紫色(excessive increase in local blood supply) |
Pigmentation色澤 | 0 | Normal color (close to normal skin) |
| 1 | Hypopigmentation色澤較淺 |
| 2 | Hyperpigmentation色澤較深 |
Total score | 13 |
|
除了燒傷疤痕外,也有人證實VSS對手術傷口的線性疤痕的評估也有效2,3。
