摘要目的:探讨双向倒刺可吸收线在乳房下垂患者"双环法"整形美容术的效果。方法:回顾性纳入2016年6月至2019年9月河南科技大学第一附属医院新区医院医疗整形美容科收治用传统可吸收缝线完成"双环法"整形美容术的乳房下垂女性患者85例[年龄24～48(36.28±6.53)岁]作为A组，另选取2019年10月至2022年2月收治用双向倒刺可吸收线完成"双环法"整形美容术的乳房下垂女性患者90例[年龄24～50(35.72±6.43)岁]作为B组。比较两组患者的切口缝合时间以及切口愈合时间，比较两组患者术后切口愈合等级、切口瘢痕程度以及患者满意度。结果:B组患者切口缝合时间、切口愈合时间分别为(13.78±2.49) min、(7.69±1.27) d，均短于A组(18.23±3.94) min、(10.36±1.78) d( t＝8.98、11.47，均 P<0.05)。两组轻度乳房下垂与中度乳房下垂的切口愈合等级比较、轻度乳房下垂与中度乳房下垂的不同切口瘢痕程度比较，差异均无统计学意义(均 P>0.05)。B组浅表性瘢痕形成率为84.44%(76/90)，高于A组的62.35%(53/85)(χ 2＝11.01， P<0.05)，增生性瘢痕和萎缩性瘢痕形成率分别为12.22%(11/90)、3.33%(3/90)，均低于A组的27.06%(23/85)、10.59%(9/85)(χ 2＝4.56、4.26，均 P<0.05)。B组患者满意度为93.33%(84/90)，高于A组的81.18%(69/85)(χ 2＝5.88， P<0.05)。 结论:双向倒刺可吸收线在乳房下垂患者"双环法"整形美容术中能够减少切口缝合及切口愈合的时间，改善患者切口美观程度，提高患者美观满意度。

abstractsObjective:To explore the effect of bidirectional barb absorbable thread in " double ring method" cosmetic surgery for breast ptosis patients.Methods:From June 2016 to September 2019, 85 patients with breast ptosis aged 24-48 (36.28±6.53) years who completed the " double loop method" cosmetic plastic surgery with traditional absorbable sutures were admitted to the Medical Plastic Surgery and Cosmetology Department of Henan University of Science and Technology First Affiliated Hospital New Area as group A. From October 2019 to February 2022, 90 patients with breast ptosis aged 24-50 (35.72±6.43) years who completed the " double loop method" cosmetic plastic surgery with bidirectional barb absorbable thread were selected as group B. The incision suture time and incision healing time were compared between the two groups, and the postoperative incision healing grade, incision scar degree and patient aesthetic satisfaction were compared between the two groups.Results:The incision suture time and incision healing time in group B were (13.78±2.49) min and (7.69±1.27) d, respectively, which were shorter than those in group A (18.23±3.94) min and (10.36±1.78) d ( t=8.98, 11.47, both P<0.05). There was no significant difference in incision healing grade between mild breast ptosis and moderate breast ptosis between the two groups ( P>0.05). There was no significant difference in incision healing grade between the two groups ( P>0.05). There was no significant difference in the degree of incision scar between mild breast ptosis and moderate breast ptosis between the two groups ( P>0.05). The formation rate of superficial scar in group B was 84.44% (76/90), which was higher than 62.35% (53/85) in group A (χ 2=11.01, P<0.05). The formation rates of hyperplastic scar and atrophic scar in group A were 12.22% (11/90) and 3.33% (3/90) respectively, which were lower than 27.06% (23/85) and 10.59% (9/85) in group A (χ 2=4.56, 4.26, both P<0.05). The total aesthetic satisfaction of group B was 93.33% (84/90), which was higher than 81.18% (69/85) in group A (χ 2=5.88, P<0.05). Conclusions:Bidirectional barb absorbable thread can reduce the time of incision suture and incision healing, improve patients′ incision aesthetics and increase the satisfactory rate.
