目的：观察应用新型缝合材料双向倒刺可吸收线（Quill? SRS线）在双环法乳房悬吊术中的应用价值。
方法：选择17例乳房下垂的病例，术前设计双环形手术切口，术中应用双向倒刺可吸收线（Quill? SRS线）连续缝合手术切口，比较以往用21例传统无齿单丝可吸收线间断缝合切口的手术缝合时间、伤口愈合情况，随访术后第6月的手术疤痕及美观效果。
结果：在双环法乳房悬吊术中应用双向倒刺可吸收线（Quill? SRS线）缝合双环形手术切口，缝合时间短，愈合时间短与传统缝合比较有显著性差异（P<0.05）,术后第6月Quill? SRS线缝合伤口的疤痕情况及美观效果优于传统缝合方式，有显著性差异。
结论：双向倒刺可吸收线（Quill? SRS线）在双环法乳房悬吊术中应用缩短手术缝合时间，抗皮肤张力强，降低疤痕增生发生率，远期美容效果好，是一种可以推广临床使用的新型缝合材料。
Objective: We aimed to prove the value of bidirectional barbed absorbable suture (QuillTM SRS suture) in periareolar mastopexy. Methods: A total of 17 cases with breast ptosis were enrolled in this study who were subjected to continuous suturing on double-circle incision designed preoperatively with QuillTM SRS suture. Compared with previous 21 cases subjected to interrupted suture with conventional nonbarb absorbable filament, suturing time, wound healing and scar appearance in 6-month follow up were studied in both groups. Results: The time of suturing and wound healing was significantly short in QuillTM SRS group compared with conventional suture group (P < 0.05). Moreover, there was obvious significance of scar appearance in 6-month follow up between two groups. Conclusion: The use of QuillTM SRS suture in periareolar mastopexy can significantly decrease suturing time, improve the long-term quality of high-tension scars by more effective tension unloading and reduce the incidence of hyperplasia of scar. Therefore, Quill SRS suture will be widely applied in clinical treatment as a new suture material.
