AbstractThere has been an increasing role in the use of injectable fillers for rejuvenation of the aging face. In this systematic review, we aim to evaluate the existing literature related to soft tissue fillers of the midface. Specifically, we focus on the non-hyaluronic acid fillers including polymethylmethacrylate (PMMA), poly-L-lactic acid (PLLA), calcium hydroxyapatite (CaHA), and autologous fat. A systematic review was conducted in November 2020 in accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines with PubMed and Embase databases. Medical Subject Headings terms used were “cheek” OR “midface” OR “malar” and “filler” OR “poly-L-lactic acid” OR “calcium hydroxyapatite,” “autologous fat” OR “polymethylmethacrylate” OR “Artefill” OR “Bellafill” OR “Radiesse” OR “Sculptra.” The initial search identified 271 articles. After 145 duplicates were removed, 126 studies were screened for relevance by title and abstract. A total of 114 studies were eliminated based on inclusion and exclusion criteria. Twelve articles underwent full-text review. Seven articles were included in the final analysis consisting of four non-hyaluronic filler products: PMMA, PLLA, CaHA, autologous fat. Most patients were highly satisfied with their results. Due to the gradual volumizing effects of PMMA, PLLA, and CaHA, patient satisfaction generally improved over time. Minor adverse reactions related to treatment included bruising, swelling, and pain. Nodule formation was reported in PLLA and CaHA studies. For autologous fat, 32% of the original injection volume remained at 16 months post-treatment, which still provided clinically improved malar enhancement. Dermal fillers are an attractive treatment option for the aging face due to their high patient satisfaction, long-lasting effects, and low side-effect profile. Patients should be appropriately counseled on the delayed effects of non-HA fillers. Autologous fat is a good option in many patients with the major drawback of unpredictable longevity, which may require a secondary procedure. Future studies should examine the longevity and long-term side effects of these fillers.

SummaryThe aim of this study was to determine the effects of intra-articular hyaluronic acid on meniscal healing. Circular defects, 1.0 mm in diameter, were made in the anterior third of the medial meniscus in rabbits. In one joint, 0.4 ml hyaluronic acid (Healon®) was instilled, and in the contralateral (control) joint, 0.4 ml Ringer’s saline. Four rabbits were killed after four, eight and 12 weeks and the menisci examined histologically. By eight weeks most of the lesions had healed by filling with hyaline-like cartilage. Healing was not improved by hyaluronic acid treatment. The repair tissue stained strongly with alcian blue, and the presence of type II collagen, keratan sulphate, and chondroitin sulphate was demonstrated by immunohistochemical localisation. In contrast to the circular defects, longitudinal incisions made in the medial menisci of a further six rabbits did not show any healing after 12 weeks, indicating that the shape of the lesion largely determined the potential for healing.The effect of hyaluronic acid on meniscal healing was tested in a rabbit model. With one millimeter circular lesions in the medial meniscus, healing by filling with hyalinelike cartilage was not significantly affected by the application of hyaluronic acid intra-articularly at the time of surgery, compared to saline controls, as assessed histologically four, eight and 12 weeks after the operation.

ABSTRACT The general change in the connective tissues which occurs in animals with experimentally produced exophthalmos, consists in an increase in the amount of hyaluronic acid, which binds the water in the connective tissue. Many regard this process as a stimulation of the mucinous system in the connective tissues, and consider this an explanation of the phenomenon of exophthalmos. When the experimental animals are injected with thyroxine or thyroid extract, the reaction observed is opposite to that seen following the injection of the anterior lobe of the pituitary gland. In the former case, there is a reduction in the amount of hyaluronic acid and consequently a decrease in the water content in the connective tissues. In the experiments in question, Na-d-thyroxine and Na-l-thyroxine), in crystalline form, were tested for their inhibiting effect on the development of exophthalmos in experimental animals. The animals used were male albino guinea-pigs. An extract of the anterior lobe of the pituitary gland (TSH Organon)) was used to produce exophthalmos. In previous work (Tengroth 1961), it was shown, using an X-ray measuring technique, that d-thyroxine, despite its poor caloric effect, like l-thyroxine had an exophthalmos-inhibiting effect. When comparing the dose-response curves of the exophthalmos-inhibiting properties of both these optical isomers, it appears that d-thyroxine has an inhibiting effect which is significantly greater than that of l-thyroxine. The significance of this observation is discussed.
