Along with advances in thread lift techniques and materials, ancillary procedures such as fat grafting, liposuction, or filler injections have been performed simultaneously. Some surgeons think that these ancillary procedures might affect the aesthetic outcomes of thread lifting possibly due to inadvertent injury to threads or loosening of soft tissue via passing the cannula in the surgical plane of the thread lifts. The purpose of the current study is to determine the effect of such ancillary procedures on the outcome of thread lifts in the human and cadaveric setting.
We used human abdominal tissue after abdominoplasty and cadaveric faces. In the abdominal tissue, liposuction parallel to the parallel axis was performed in one area for 5 min. We counted 30 passes when liposuction was performed in one direction. This was repeated as we changed the direction of passages. The plane of thread lifts (dermal vs subcutaneous) and angle between liposuction and thread lifts (parallel vs perpendicular) were differentiated in this abdominal tissue study group. Then, we performed parallel or perpendicular thread lifts using a small slit incision. Using a tensiometer, the maximum holding strength was measured when pulling the thread out of the skin as much as possible. We also used faces of cadavers to prove whether the finding in human abdominal tissue is really valid with corresponding techniques.
Our pilot study using abdominal tissue showed that liposuction after thread lifts adversely affects it regardless of the vector of thread lifts. In the cadaveric study, however, liposuction prior to thread lifting does not significantly affect the holding strength of thread lifts.
Liposuction or fat grafting in the appropriate layer would not be a hurdle to safely performing simultaneous thread lifts if the target lift tissue is intra-SMAS or just above the SMAS layer.

随着线材提升技术和材料的进步，同时进行了辅助程序，如脂肪移植、抽脂或填充物注射。一些外科医生认为，这些辅助程序可能会影响线材提升的美学效果，这可能是由于在手术平面上穿过套管时意外损伤线材或软组织松动。本研究的目的是确定在人体和尸体环境中，这些辅助程序对线提升效果的影响。
我们使用了腹部整形术后的人体腹部组织和尸体面部。在腹部组织中，在一个区域内沿平行轴进行了 5 分钟的平行脂肪抽吸。当一个方向的脂肪抽吸进行 30 次时，我们进行了计数。当我们改变通道方向时，会重复这个操作。在这个腹部组织研究组中，我们区分了线材提升的平面（真皮与皮下）和脂肪抽吸与线材提升之间的角度（平行与垂直）。然后，我们通过一个小的切口进行平行或垂直的线材提升。使用张力计，尽可能地从皮肤中拔出线材时，测量最大保持强度。我们还使用了尸体的面部来证明人体腹部组织中的发现是否真的有效。
我们使用腹部组织进行的初步研究表明，无论线材提升的向量如何，线材提升后的脂肪抽吸都会对其产生不利影响。然而，在尸体研究中，在进行线材提升之前进行脂肪抽吸并不会显著影响线材提升的保持强度。
如果目标提升组织位于 SMAS 内或仅在 SMAS 层上方，则在适当的层中进行抽脂或脂肪移植不会成为安全进行同时线材提升的障碍。
