Tofacitinib for managing granuloma formation after dermal filler injection: three case reports and literature review.

BACKGROUND: Granuloma formation is an uncommon and persistent skin inflammatory condition caused by the injection of dermal fillers. The exact cause of this reaction is not well understood, but it may be associated with irritating components or abnormal immune function. Treating granulomas can be difficult. However, recent research has shown that Janus kinase (JAK) inhibitors hold promise as a potential therapy for refractory granulomatous diseases. OBJECTIVES: The aim was to evaluate the efficacy and safety of tofacitinib as a treatment for granulomas secondary to filler injection and the possible mechanisms were discussed and summarized. METHODS: This study focuses on three cases of patients who experienced granuloma formation after receiving filler injections and were subsequently treated with tofacitinib. The efficacy and safety of the treatment were evaluated using parameters such as photographs and monitoring for any adverse reactions. In addition, a literature review was conducted to explore the underlying mechanisms and potential effects of tofacitinib. RESULTS: All three cases recovered from swelling and nodules without side effects through the off-label use of oral tofacitinib. Existing data review reveals some approaches for cutaneous granulomatous disorders like inhibiting macrophage activation and downregulation of the JAK-STAT pathway. CONCLUSION: This report emphasizes the effectiveness of JAK inhibitors in treating granulomas caused by filler injections. Recent advancements in understanding the underlying mechanisms of granulomatous reactions have paved the way for JAK inhibitors to be regarded as a promising treatment choice. However, further research is necessary to fully assess the safety and long-term effectiveness of using tofacitinib for granuloma treatment.

Effectiveness and Safety of a New Hyaluronic Acid Injectable for Augmentation and Correction of Chin Retrusion.

BACKGROUND: A hyaluronic acid (HA) filler intended for non-surgical improvement of chin appearance should ideally be of high strength/firmness (high G') to allow for deep injections on the bone. HASHA (Restylane Shaype) is a new hyaluronic acid (HA) injectable with high G' and high HA concentration (25 mg/mL), engineered by the new NASHA-HD (High Definition) technology. HASHA is suitable to be placed periosteally, aiming to mimic the natural shape of the bony chin. This pivotal clinical investigation evaluated effectiveness and safety of HASHA for augmentation and correction of chin retrusion.  Methods: Subjects 18 years or older with mild or moderate chin retrusion by the Galderma Chin Retrusion Scale (GCRS), were randomized 3:1 to HASHA (n=103) or no treatment (n=37). Assessments included GCRS (blinded evaluator), aesthetic improvement (Global Aesthetic Improvement Scale [GAIS]), subject satisfaction, and safety.  Results: GCRS responder rate (1-grade or greater improvement from baseline) was significantly higher for HASHA (83.3%) versus controls (10.8%) at month 3 (P<0.001) and maintained through month 12 (P<0.001). Aesthetic improvement was high throughout the study in the HASHA group, according to investigators (97% or greater) and subjects (89% or greater). Overall, subject satisfaction was high at month 3 and maintained at month 12. Product- or injection-related adverse events were mostly mild or moderate and transient. No product- or injection-related serious adverse events were reported. CONCLUSIONS: HASHA, a new NASHA-HD injectable with extra strength/firmness, was safe and effective for chin augmentation and correction of chin retrusion, with high aesthetic improvement and subject satisfaction throughout 12 months.

Periorbital Rejuvenation.

The periorbital region can be rejuvenated by the application of both neuromodulators and dermal fillers. Neuromodulators can elevate the brows and improve periorbital rhytids. Dermal fillers can camouflage orbital fat pseudoherniation and tear trough deformity.

Complications of Injectables.

The field of non-surgical esthetic procedures has witnessed a significant surge in demand in recent years, with neuromodulators, skin treatments, and dermal fillers contributing significantly to the industry's growth. These procedures have become increasingly popular, reflecting the broader acceptance of esthetic enhancements in society. Neuromodulators play a pivotal role in facial rejuvenation, but they require precise knowledge of facial anatomy to optimize results and prevent complications. They include rare hypersensitivity reactions, local injection reactions, and brow and eyelid ptosis. Dermal fillers, both non-permanent and permanent, are widely used to restore volume and improve facial contours. However, they also carry risks, including bruising, temporary edema, and lumps. Permanent fillers present higher complication rates, and their use should be approached with caution. Vascular occlusion is a rare but severe complication associated with dermal fillers. To mitigate these risks, practitioners must have a comprehensive understanding of their compositions and potential complications. Overall, while non-surgical esthetic procedures offer remarkable results with minimal downtime, the importance of training, anatomic knowledge, and effective complication management cannot be overstated in ensuring patient safety and satisfaction in this evolving field of medicine.

Impurities in Hyaluronic Acid Dermal Fillers? A Narrative Review on Nonanimal Cross-Linked Fillers.

Importance: Nonanimal cross-linked hyaluronic acid (HA) dermal fillers are among the most versatile tools in minimal invasive esthetic medicine. Filler injections aim to volumize, provide contour, and reduce wrinkles and skinfolds. In the hand of the experienced user, HA fillers have an excellent safety profile. Nevertheless, adverse events have been reported related to poor injection techniques, infection, and immune reactions. Observations: In this review, the focus is on filler impurities. Impurities can originate from the fermentation process, crosslinking, packaging, and contamination. Impurities consist of particular and nonparticular matter. We discuss possible risks for the patient to be treated with HA fillers. Conclusions and Relevance: Impurities of dermal fillers bear a potential risk for patients, such as delayed autoimmune and inflammatory reactions, biofilm formation, and exposure to leachable Endocrine Disrupting Chemicals. Amount and quality of impurities can be considered as one of the quality parameters of commercially fillers. Considering patient safety, filler impurities should be further reduced.

Chin Augmentation and Treatment of Chin Retrusion with a Flexible Hyaluronic Acid Filler in Asian Subjects: A Randomized, Controlled, Evaluator-Blinded Study.

BACKGROUND: Aesthetic improvement of the chin is increasingly requested by patients, including those of Chinese origin. METHODS: A randomized, evaluator-blinded, no-treatment controlled study evaluated the effectiveness and safety of a flexible hyaluronic acid (HA) filler, Restylane® DefyneTM (HADEF), in the correction of chin retrusion in a Chinese adult population over 12 months after treatment. On Day 1, subjects were randomized 3:1 into two groups, HADEF or delayed-treatment controls, and those in the HADEF group were administered treatment. An optional touch-up treatment was administered 1 month after treatment to obtain optimal chin augmentation. The initially untreated control group was offered delayed-treatment after 6 months (including 1-month touch-up). RESULTS: HADEF was superior to no-treatment in improving chin retrusion according to the blinded evaluator at 6 months [Galderma Chin Retrusion Scale (GCRS) responder rate (≥ 1-point improvement from baseline) of 81% vs. 5% for untreated controls; p < 0.001, meeting the primary effectiveness objective. A majority of subjects maintained improvement at 12 months (61% in the HADEF group). All subjects reported satisfaction with results at 6 months after treatment with HADEF and aesthetic improvement rates per the global aesthetic improvement scale (GAIS) were high for 12 months following treatment, with an acceptable safety profile. CONCLUSIONS: These results demonstrated HADEF to be effective and safe for the correction of mild-to-moderate chin retrusion in Chinese subjects, confirming findings previously observed in a western population.

BACKGROUND: The demand for nonsurgical facial rejuvenation options is growing, yet the periorbital region remains an area of relative unmet need. This review explores nonsurgical options for facial rejuvenation and the role of oxymetazoline hydrochloride ophthalmic solution, 0.1%, in treating age-related blepharoptosis as part of periorbital rejuvenation. METHODS: Advisors experienced in facial rejuvenation met to discuss existing literature on the upper face and periorbital rejuvenation and the role of oxymetazoline hydrochloride ophthalmic solution, 0.1%, in treating facial aging. RESULTS: An array of nonsurgical options exist to address the signs of aging, including minimally invasive treatments, such as botulinum toxin injections and dermal fillers, and noninvasive therapy, such as lasers, chemical peels, and microdermabrasion. However, treating age-related ptosis in periorbital rejuvenation is mainly addressed surgically. The newly approved α-adrenergic receptor agonist oxymetazoline hydrochloride ophthalmic solution, 0.1%, provides a novel non-interventional approach to blepharoptosis. CONCLUSIONS: Facial rejuvenation is highly sought-after in this post-pandemic era. Each nonsurgical treatment option has its advantages and drawbacks. A patient-centered approach is necessary to select the appropriate procedure considering the patient's concerns and aesthetic sensibilities. The eyes are an area of primary concern for patients, yet surgery is the gold standard for treating ptosis. Oxymetazoline hydrochloride ophthalmic solution, 0.1%, is a safe and effective nonsurgical treatment for blepharoptosis.

Causes and management of sight threatening complications of dermal filler injections: A review.

Injectable dermal fillers continue to increase in popularity in aesthetic medicine. Although rare, vision loss secondary to filler injections is a devastating complication associated with a poor visual prognosis. The mechanism for vision loss is thought to be related to retrograde embolization of the dermal filler from peripheral vessels in the face into the ophthalmic arterial system. Early recognition and prompt management are essential if vision is to be salvaged. The use of retrobulbar hyaluronidase is still contentious, however when administered by a specialist, this treatment gives the best chance at visual recovery and should be considered for all cases.

A treatment algorithm for hyaluronic acid filler related complications of the face.

BACKGROUND: Throughout the last decade, a notable increase in HA-filler-related complications have been observed, owing to the increase in demand for filler injections and availability of multiple products. OBJECTIVES: The aim is to provide practical advice on the best way to prevent and treat HA-filler-related complications. METHODS: Thirty patients who experienced visible and/or symptomatic complications localized within the facial area were treated according to our algorithm. Patients with inflammatory lesions underwent antibiotic and anti-inflammatory therapy, followed by hyaluronidase injections. Patients with abscesses were treated with antibiotics, incision, and drainage. Each patient completed the dermatology-specific quality of life questionnaire (DLQI) at the first and last examinations. RESULTS: Among the 29 patients who received antibiotic therapy, 3 healed without further treatment. However, 18 received hyaluronidase injections, 9 underwent incision and drainage, and 5 presented with fistulas and developed retracted scars. Moreover, 80% of the patients were completely healed, 13% significantly improved, and 3% did not show any improvement. The DLQI scores analysis showed a notable impact of patients' diseases on their quality of life, mainly in the terms of personal relationships and symptoms, with minor impacts on intimate relationships, ability to work, and study. We demonstrated that our algorithm resulted in a significant improvement in the overall quality of life at the last follow-up (p < 0.001). CONCLUSIONS: The use of filler injections requires caution and specific training because they can lead to serious complications. If these complications are recognized promptly, healing can be optimized. Our treatment algorithm demonstrated high rate of healing and significant improvement in the patients' quality of life.

Optimizing Facial Aesthetics: Sequential Application of Botulinum Toxin A and Dermal Fillers for Enhanced Results.

In recent years, the field of aesthetic medicine has witnessed significant advancements, offering patients a plethora of options to rejuvenate their appearance. Among the most popular techniques are the administration of botulinum toxin A (BoNT-A) and dermal fillers. This article delves into the rationale and benefits of preparing the face with BoNT-A to weaken depressor muscles before proceeding with dermal filler injections. This sequential approach not only enhances patient outcomes but also improves procedural safety and patient satisfaction while reducing the chances of needing filler. This article reviews the anatomy, scientific evidence, and clinical implications supporting this innovative approach while shedding light on the potential for revolutionizing facial aesthetic procedures. With advanced applications of BoNT-A, it is possible to slim round faces, reduce jowling, create hollowing in some patients by obliterating masseters, slim the parotid, extend the chin, and more.

Multifocal strokes and vision loss from PDLLA filler injections.

BACKGROUND: Poly-D, L-lactic acid (PDLLA) is increasingly used as a commercial dermal filler due to its lasting cosmetic properties. Consequently, PDLLA-related vascular complications are increasingly recognized and described. Herein, we describe the first known occurrence of multifocal strokes from the use of PDLLA as a cosmetic dermal filler, and discuss the mechanisms facilitating PDLLA's entry into the intracranial arterial system. CASE PRESENTATION: A middle-aged female presented with acute vision loss of both eyes immediately after dermal injections of PDLLA to her nasolabial folds and infraorbital regions. There were no additional neurological deficits. Dilated fundal examination revealed retinal edema bilaterally, with deposition of filler material in the retinal arteries. Magnetic resonance imaging of her brain and orbits demonstrated multifocal strokes (left caudate head, right medial frontal lobe) and ischemia of the left optic nerve. The temporal proximity of the dermal injections to her symptoms, guided by fundal examination and neuroimaging findings, allowed us to attribute her strokes and ischemic optic neuropathy to PDLLA's entry into, and embolism within, the intracranial arterial system. She was treated with hyperbaric oxygen therapy and experience improvement to her right eye's vision, although poor vision persisted in her left eye. CONCLUSION: While PDLLA is generally considered safe, its increasing use as a cosmetic filler renders it crucial for physicians to be cognizant of its vascular complications, especially when early recognition and treatment are essential in mitigating their devastating ramifications.

Does injecting small amounts of fillers prevent the development of secondary blindness?

INTRODUCTION: Inadvertent entry of filler products into the supratrochlear, supraorbital, or dorsal nasal arteries, among other branches of the ophthalmic artery, might result in an immediate and devastating loss of vision. We wanted to examine how much filler could block the ophthalmic artery. MATERIALS AND METHODS: Twenty-nine fresh cadavers were examined. We exposed the arterial supply to the opthalmic artery by dissecting the orbital area. Thereafter, 17 filler injections were introduced into the supratrochlear, supraorbital, and dorsal nasal arteries each. The amount of filler injection that completely blocked the ophthalmic artery was measured. Additionally, one of the head specimens was processed using phosphotungstic acid-based contrast enhancement micro-computed tomography to analyze each arteries to obstruct its whole ophthalmic artery. RESULTS: The supratrochlear, supraorbital, and dorsal nasal arteries had mean volumes in milliliter (mean ± standard deviation) of 0.0397 ± 0.010 mL, 0.0409 ± 0.00932 mL, and 0.0368 ± 0.00732 mL, respectively. However, the arteries did not differ significantly. CONCLUSION: Even a modest amount of filler injection can completely block the ophthalmic artery, resulting in visual loss.
