Absorbable suture material (Fast Absorbing Gut [FG], Ethicon, Somerville NJ) is often used for patient convenience; however, the optimal diameter of FG sutures is debatable.
To determine whether the use of 6-0 FG during repair of linear cutaneous surgery wounds on the head and neck improves scar cosmesis compared with the use of 5-0 FG.
This was a prospective, randomized, split-scar intervention in patients undergoing repair of linear cutaneous wounds on the head and neck. The scar was assessed 3 months after surgery via the Physician Observer Scar Assessment Scale (POSAS), a validated instrument.
The difference in the sum of the POSAS component scores for 6-0 FG (12.03) compared with that for 5-0 FG (13.11) was not statistically significant (P = .26). Observer overall opinion was similar for both interventions, at 2.49 for 6-0 FG vs 2.64 for 5-0 FG (P = .54). The difference in the number of complications in the 5-0 FG group (15) vs the 6-0 FG group (10) was not statistically significant (P = .40).
Single-center study with wounds limited to the head and neck in white individuals, with a predominance of men.
For linear repair of cutaneous wounds, 6-0 FG was not statistically different for cosmetic outcomes, scar width, and complications compared with 5-0 FG.
可吸收缝线材料（Fast-Absorbing Gut [FG]，Ethicon，Somerville NJ）常用于方便患者；然而，FG 缝线的最佳直径存在争议。
确定在头颈部线性皮肤外科伤口修复中使用 6-0 FG 是否比使用 5-0 FG 更能改善疤痕美容效果。
这是一项前瞻性、随机、分割疤痕干预研究，纳入在头颈部接受线性皮肤伤口修复的患者。术后 3 个月，使用 Physician Observer Scar Assessment Scale（POSAS）评估疤痕，POSAS 是一种经过验证的工具。
6-0 FG（12.03）与 5-0 FG（13.11）的 POSAS 各组成部分评分总和之间的差异无统计学意义（P=.26）。两种干预措施的观察者整体意见相似，6-0 FG 为 2.49，5-0 FG 为 2.64（P=.54）。5-0 FG 组（15 例）与 6-0 FG 组（10 例）的并发症数量差异无统计学意义（P=.40）。
单中心研究，伤口仅限于头颈部，且均为白人，男性居多。
对于线性皮肤伤口修复，与 5-0 FG 相比，6-0 FG 在美容效果、疤痕宽度和并发症方面无统计学差异。
