The Keller funnel is an easy-to-use mechanical device that aids breast implant insertion. This study analyzed implant insertion time and incision length using the Keller funnel versus conventional manual insertion.
This was an analysis of two cohorts of adult patients undergoing primary breast augmentation with anatomical implants at a single center. In the 'insertion time cohort' (N = 20), implants were inserted with a Keller funnel on one side and manually on the other; follow-up lasted 4 years. In the 'incision length cohort,' both implants were inserted with a Keller funnel (N = 50) or manually (N = 50), with follow-up lasting 12 months.
In the insertion time cohort, mean total insertion time (from implant sterile-package opening to final positioning in the pocket) was 35 s (range 13-76 s) with the Keller funnel and 25 s (range 13-43 s) using manual insertion (p = 0.07); the mean time needed to push the implant through the incision was 6 s (range 3-10 s) with the Keller funnel and 16 s (range 13-40 s) with manual insertion (p = 0.04). In the incision length cohort, mean incision length was shorter with the Keller funnel versus manual insertion (35.5 ± 2.1 mm vs. 46.2 ± 3.2 mm; p < 0.001). There were no differences in complications based on insertion method.
The Keller funnel was associated with decreased incision length and reduced time to push the implant through the incision. This brings potential clinical advantages in minimizing scarring and reducing contamination of the device.

凯勒漏斗是一种易于使用的机械设备，有助于乳房植入物的插入。本研究分析了使用凯勒漏斗与传统手动插入方式时的植入物插入时间和切口长度。
这是一项对在单一中心接受初次解剖型乳房增大术的成年患者的两个队列进行的分析。在“插入时间队列”（N = 20）中，一侧乳房使用凯勒漏斗插入植入物，另一侧手动插入；随访持续4年。在“切口长度队列”中，两组植入物均使用凯勒漏斗（N = 50）或手动（N = 50）插入，随访持续12个月。
在插入时间队列中，使用凯勒漏斗时，平均总插入时间（从打开植入物无菌包装到在囊袋中最终定位）为35秒（范围13 - 76秒），手动插入时为25秒（范围13 - 43秒）（p = 0.07）；使用凯勒漏斗将植入物推过切口所需的平均时间为6秒（范围3 - 10秒），手动插入时为16秒（范围13 - 40秒）（p = 0.04）。在切口长度队列中，与手动插入相比，使用凯勒漏斗时平均切口长度更短（35.5 ± 2.1毫米对46.2 ± 3.2毫米；p < 0.001）。基于插入方法的并发症无差异。
凯勒漏斗与切口长度缩短以及将植入物推过切口的时间减少相关。这在最小化瘢痕形成和减少器械污染方面带来了潜在的临床优势。
