A frequent facial abnormality called chin retrusion, also known as retrognathia, can be detrimental to a person\'s self-esteem and overall face aesthetics. Hyaluronic acid (HA) injections are one non-surgical approach to this problem that may provide individuals seeking chin augmentation with a relatively less invasive and potentially more affordable alternative. The present literature does not provide enough in-depth systematic reviews of the use of HA in chin augmentation. By completing a complete examination of the information that is currently available, this study intends to fill this knowledge gap, supporting physicians and researchers in better comprehending the efficacy and implications of HA in chin augmentation. The safety and success of any esthetic procedure should be made based on the results reported by the patients, including satisfaction and quality of life. Patients need to receive comprehensive surgical instructions from a medical professional to optimize the results of the HA injections for chin enhancement surgery. Regardless of the reported safety of using HA injections, some unwanted side effects have also been recorded. Indeed, healthcare professionals can make more informed decisions and give a patient comprehensive information about the procedure\'s risks and benefits to the patients. A systematic review was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. EMBASE, OVID, and Google Scholar databases were searched up to June 2023. We concentrated on adult patients treated with HA for chin enhancement, and our research was limited to studies conducted in English. A total of 2,738 patients from 24 articles were studied, with 2,259 receiving HA injections for chin augmentation. When applicable, aesthetic outcomes were assessed using scales such as the Global Aesthetic Improvement Scale (GAIS)/FACE-Q and the Galderma Chin Retrusion Scale. Patient satisfaction increased noticeably. Among the studies, some reported complications following HA injection. While three studies found no significant negative effects, one highlighted a major necrotic complication. HA has proven to be an effective and safe alternative to chin augmentation surgery, with the majority of patients showing high satisfaction rates. However, large-scale randomized controlled trials are needed to obtain meaningful results, which will contribute to the further development of non-surgical cosmetic procedures. These studies may facilitate further innovation and refinement of these techniques and potentially expand the application of HA fillers in facial aesthetics.

The emergence and popularity of cosmetic facial procedures may lead to significant ophthalmic complications such as ocular motility dysfunction and visual disability. Here, we present a scoping review to identify common ophthalmic complications in some facial plastic surgeries and cosmetic injections, and to develop clinical approaches for prophylaxis and management in terms of direct attention and awareness of non-ophthalmologists toward such scenarios and appropriate intervention. This review was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. The following keywords were used to search PubMed, Scopus, Web of Science, and Google Scholar: \"facial laser\", \"facial fillers\", \"facial injections\", \"hyaluronic acid\", \"local facial injections of botulinum toxin\", \"rhinoplasty\", \"blepharoplasty blindness\", \"ophthalmoplegia\", \"diplopia\", \"ptosis\", \"ophthalmic artery occlusion\", \"posterior ciliary artery occlusion\", and \"ocular ischemic syndrome\". A total of 37 articles published between 1989 and 2021 were included, of which 21 were case reports. The most common ophthalmic complication was vision loss (0.0008%). The risk of ophthalmic complications including ocular pain, sudden unilateral or bilateral vision loss, flashes of light, ptosis, and ophthalmoplegia increase with injection in common anatomical regions like the glabella, nose, and supraorbital and nasolabial folds. The incidence of adverse events ranges from 5% to 18% in rhinoplasty. The most common complications after blepharoplasty were dry eye syndrome and diplopia, caused by eyelid ptosis. Eyelid, cornea, lens, and retina injuries are ophthalmic complications that occur after facial laser treatment. Ophthalmic complications after non-ophthalmic and cosmetic procedures are becoming increasingly common. The cumulative reported cases of ophthalmic complications after hyaluronic acid filler injection from 2016 to 2020 showed different types of adverse events, with the most common being decreased visual acuity, unilateral vision loss, and ptosis, with varying outcomes of each complication ranging from partial resolution to complete recovery. These complications must be recognized early, and prompt treatment must be established.

UNASSIGNED: This retrospective review assesses the efficacy and safety of low-dose triamcinolone (1mg/cc) added to hyaluronic acid fillers to decrease swelling after infraorbital injection.
UNASSIGNED: This retrospective analysis includes 447 patients who underwent 706 infraorbital hyaluronic acid filler treatments from April 2013 to March 2020 by a single injector. Short-term post-procedural swelling (≤2 weeks) was assessed through follow-up phone calls, which were documented in patient charts. The effect of triamcinolone, filler type, volume, and patient characteristics on the rate of post-procedure swelling were analyzed.
UNASSIGNED: Swelling after infraorbital hyaluronic acid filler occurred in over half of the patients (51%, 103/202), but significantly decreased (23%, 29/124) when 1mg/cc of triamcinolone was mixed with the filler (x2[1, N=326]=24.296, p<0.00001). The incidence of swelling was directly correlated with the amount of hyaluronic acid filler injected (37% ≤ 0.55cc, 51% 0.56-1cc, and 60% >1cc) [x2[1, N=95]=3.9231, p=.048]. There was no significant difference in patient age, sex, Fitzpatrick skin type, or history of allergies on incidence of post-procedure swelling. Adverse events were limited to expected injection-site reactions, and there were no reports of hypopigmentation or atrophy from the addition of triamcinolone.
UNASSIGNED: This is a retrospective study that used patient reporting for short-term post procedure swelling.
UNASSIGNED: This is the first retrospective study showing the safety and efficacy of a novel technique adding low-dose triamcinolone (1mg/cc) to hyaluronic acid filler to reduce post-procedure swelling within the first few weeks following infraorbital injection. Additionally, using lower volumes is also effective at reducing post-procedure swelling. Larger, randomized, controlled trials are needed to support our findings.

BACKGROUND: It is believed that combination treatment with both neuromodulators (NM) and hyaluronic acid soft-tissue fillers (HA) results in superior aesthetic results and increased patient satisfaction compared to either treatment alone.
OBJECTIVE: To determine whether combined treatment with NM and HA leads to greater patient retention than treatment with NM or HA alone.
METHODS: This is a large, multi-center, retrospective review of patient retention rates from 7 aesthetic practices across 5 continents, incorporating over 2600 patients. Patient retention is interpreted as a surrogate marker for overall patient satisfaction. Retention rates were compared at 1, 3, and 5 years for patients who received NM only, HA only, or combination treatment with both NM and HA.
RESULTS: Combination therapy significantly increased the probability of retention for each time point (1, 3, and 5 years) compared with NM alone (P < .0001) and HA alone (P < .0001).
CONCLUSIONS: This large multicenter, global retrospective review demonstrates that patients who received combined HA and NM were more likely to be retained in the same practice over many years than those who received either treatment alone.
