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.

Cosmetic Medicine

Most popular fillers in cosmetic medicine are hyaluronic acid based. These comprise over 90% of the market and come with the advantage to be soluble in case of complications. Other fillers are contained in the group of bio-stimulatory fillers. They exert a secondary volumizing effect by provoking a low-grade inflammatory response that produces extra collagen. Examples are calcium-hydroxyapatite and L-poly-lactid acid. Finally autologous fat is being used as a filling substance (lipofilling). The gravest complications with fillers are intravascular injections. In particular when injected in arteries fillers can block blood flow and lead to skin necrosis or vison loss in case the material occludes the Central Retinal Artery (CRAO). Two opposing theories about the nature of arterial occlusion exist. One based on Ian Taylor idea of choke anastomoses assume vasoconstriction induced by the filler, both of the primary offended artery and its anastomosing vasosomes. In this case resolving the hyaluronic acid filler with the enzyme hyaluronidase at the primary occluding location would suffice. This is done under ultrasound guidance. The other theory assumes displacement of parts of the filler to end arterioles. Then, the whole affected area has to be flooded with large dosages of hyaluronidase. Obstructions with fillers based on other materials cannot be resolved. It seems logical to prevent intra-arterial filler injection by duplex sonography detection of the course of arteries prior to injection. Ultrasound has additional advantages for cosmetic doctors such as recognizing remains of previously injected filler. It also can give feedback on a physician’s ability to inject filler in the correct subdermal location.

Abstract Background This is the first study to evaluate the effect of premaxillary filler injection on nasal tip projection, upper lip projection, and upper lip vermilion height. Objectives The primary objective of this study was to analyze the change in nasal tip projection (measured by the Goode ratio) and the change in upper lip projection (measured by the Z angle) following premaxillary hyaluronic acid injection. A secondary objective was to measure the change in upper lip vermilion height. We hypothesized that treated subjects will show an increase in nasal tip projection, upper lip projection, and upper lip vermilion height. Methods Twenty volunteer patients with signs of perioral aging or poor upper lip projection were enrolled in this prospective cohort study and underwent premaxillary hyaluronic acid filler injection between November 2017 and June 2018. Nasal tip projection, upper lip projection, and upper lip vermilion height were assessed from baseline and posttreatment photographs based on the Goode ratio, Z angle, and lip vermilion height ratio, respectively. Results No significant change was noted between pre- and posttreatment Goode ratio measurements (P = 0.841). There was a significant decrease in Z angle and therefore significant increase in upper lip projection with treatment (P < 0.001). The lip vermilion height ratio demonstrated a trend of increased upper lip vermilion height but this did not achieve statistical significance (P = 0.561). Conclusions Premaxillary filler treatment resulted in a significant increase in upper lip projection. Premaxillary filler injection when performed in a safe manner is a valuable treatment option for perioral rejuvenation. Level of Evidence: 4
