Abstract Background Aspiration testing before filler injection is controversial. Some believe that aspiration can help prevent inadvertent intravascular injection, while others cite false-negative results and question its value given that the needle position always changes somewhat during injection procedures. Objectives To test the relation of false-negative results to the viscosity of the material within the needle lumen and determine whether a less viscous material within the needle lumen could decrease the incidence of false-negative results. Methods In vitro aspiration tests were performed using 30-G and 27-G needle gauges, two cross-linked hyaluronic acid fillers, normal saline bags pressurized at 140 and 10 mmHg to mimic human arterial and venous pressures, and three needle lumen conditions (normal saline, air, and filler). Testing was repeated three times under each study condition (72 tests in total). For in vivo correlation, aspiration tests were performed on femoral arteries and central auricular veins in three rabbits (4–5 aspirations per site, 48 tests in total). Results In vitro and in vivo testing using 30-G needles containing filler both showed false-negative results on aspiration testing. In vitro and in vivo testing using needles containing saline or air showed positive findings. Conclusions False-negative results from aspiration testing may be reduced by pre-filling the needle lumen with saline rather than a filler. The pressurized system may help overcome challenges of animal models with intravascular pressures significantly different from those of humans. The adaptability of this system to mimic various vessel pressures may facilitate physiologically relevant studies of vascular complications.

Abstract Background One of the primary goals of enucleation and evisceration surgery is the restoration of an adequate orbital volume through the use of appropriately sized alloplastic or autogenous tissues. In patients inadequately treated, post-enucleation or evisceration socket syndrome occurs. Fillers are an ideal alternative for eyelid and eyebrow arcade volume enhancement since their injection is easily performed in an outpatient setting avoiding several complications. The aim of this study is to report the use of hyaluronic acid (HA) fillers to treat volume deficits of the upper and lower eyelids, projecting the brow arcade and reducing the asymmetry. Methods Thirteen patients (2 male, 11 female, mean age 32.7 years) were treated from June 2012 to May 2020. Non-surgical treatment by HA filler injection for aesthetic rehabilitation of deep superior sulcus, inferior tear trough deformity, and scleral show was performed. Results No complications as orbital-ache and/or vasovagal response were reported during the injections. Minor complications such as light swelling at the site of injection, self-resolved within 2 days, were recorded. Stable results were observed at follow-ups. In two cases, two successive treatments were required at 3 and 6 years from the first injection. Conclusions Hyaluronic acid fillers offer a versatile and safe method for replacing soft tissue lost from the upper eyelid/brow complex in cases of post-enucleation or evisceration socket syndrome. Level of evidence: Level IV, therapeutic study.
