The tear trough deformity is a sign of eye aging. Filling is an ideal choice for the tear trough accompanied by infraorbital hollows.
To evaluate the efficacy and safety of stromal vascular fraction gel (SVF-gel) as a filler for the tear trough deformity which is combined with infraorbital hollows.
From July 2017 to June 2018, 33 patients underwent autologous fat aspiration and were followed up successfully. Stromal vascular fraction gel was used to correct patients with bilateral Barton I/II; tear trough deformity and infraorbital hollows. Improvement was evaluated by measuring skin-periosteal depth, 3D volume, global aesthetic improvement scale (GAIS), and patient self-assessment.
Skin-periosteal depth improved significantly (p < .001). The volumetric increment of the tear trough and infraorbital regions increased 2.132 ± 0.671 mL, and the retention rate was excellent (72.87 ± 10.23%). The GAIS showed a high score (2.5 ± 0.5 points), with patient self-assessment showing satisfactory results for all 7 questions on the questionnaire.
The high retention rate of SVF-gel suggests that it can provide an effective solution to tear trough deformity accompanied by infraorbital hollows.
泪槽畸形是眼睛衰老的标志。填充是治疗伴有眶下凹陷的泪槽畸形的理想选择。
评估基质血管成分凝胶（SVF-gel）作为一种填充物治疗伴有眶下凹陷的泪槽畸形的疗效和安全性。
自 2017 年 7 月至 2018 年 6 月，33 例患者接受了自体脂肪抽吸术，并成功随访。使用基质血管成分凝胶矫正双侧 Barton I/II 型；泪槽畸形和眶下凹陷。通过测量皮肤-骨膜深度、3D 体积、整体美学改善量表（GAIS）和患者自我评估来评估改善情况。
皮肤-骨膜深度显著改善（p<0.001）。泪槽和眶下区域的体积增量增加了 2.132±0.671mL，保留率非常好（72.87±10.23%）。GAIS 评分较高（2.5±0.5 分），所有 7 个问卷问题的患者自我评估均显示满意结果。
SVF-gel 的高保留率表明，它可以为伴有眶下凹陷的泪槽畸形提供有效的解决方案。
