Delayed onset filler complication: Two case reports and literature review

Clinical Management With High-Frequency Ultrasound of Recurrent Submental Abscess Formation After Filler Placement: Bacterial Contamination or Immune-Mediated Adverse Event?

The authors present a case of a 29-year-old female patient with a recurrent submental abscess formation after chin augmentation with highly reticulated hyaluronic acid filler. We evaluate the possible cause of this complication and the result after clinical management with ultrasound-guided injection of hyaluronidase. We highlight the prevention, assessment and treatment with real-time imaging of hyaluronidase injection in the affected area, as a predictable approach for both the patient and the physician.

Comparative In Vivo Study of Solid-Type Pure Hyaluronic Acid in Thread Form: Safety and Efficacy Compared to Hyaluronic Acid Filler and Polydioxanone Threads

INTRODUCTION

Although various products are commonly used for skin rejuvenation, solid-type hyaluronic acid (HA) as an injectable form has not been researched or utilized. This study aimed to demonstrate the safety and efficacy of solid-type HA in thread form, which differs from the conventional gel-type HA commonly used.

METHOD

Solid-type HA threads, conventional HA fillers, and polydioxanone (PDO) threads were inserted into the dorsal subcutaneous layer of mice. Photographs were taken on days 0, 1, 3, and 7, and on day 7, the samples were harvested for histological analysis. Inflammatory reactions and detection of collagen were confirmed through tissue staining, and real-time PCR was conducted to quantify collagen synthesis.

RESULTS

In the histological analysis, the PDO threads exhibited a greater inflammatory response compared to the HA threads. Masson's trichrome staining revealed a higher degree of collagen synthesis in the HA thread group compared to the HA filler group. While collagen type 1 expression was significantly higher in the PDO thread group than in the HA thread group, the HA thread group showed higher expression levels of collagen type 3. Furthermore, the PDO thread group demonstrated a statistically significant increase in TGF-β1 compared to the HA group.

CONCLUSION

This in vivo study demonstrated the stable application of solid-type pure HA threads and their potential for inducing collagen production, while also yielding a low inflammatory response. The findings highlight the promising applications of solid-type HA in the field of cosmetic dermatology.

Personalization of Minimally-Invasive Aesthetic Procedures with the Use of Ultrasound Compared to Alternative Imaging Modalities

Ultrasonography is a well-tolerated procedure that aids in the targeted esthetic therapies of special cutaneous regions, as well as in the prevention (vascular mapping, identification of previous filler, and others) and management of potential complications (vascular occlusion, external vascular compression, product misplacement or migration, inflammatory reactions, and others). It has lately been promoted as the first-line imaging tool to address injectables. In this article, we aim to review the evolving role of ultrasonography in cosmetic filler procedures, from the fundamental ultrasound characterization of cosmetic fillers to the ultrasound-enhanced detection and management of cosmetic filler complications, including ultrasound's role in hyaluronidase-guided injections for cosmetic filler dissolution. Furthermore, the paper explores the integral role played by ultrasound in enhancing the precision, efficacy, and safety of additional minimally invasive aesthetic techniques such as mesotherapy, radiofrequency, cryolipolysis, and polydioxanone procedures.

Vascular complications with necrotic lesions following filler injections: Literature systematic review

INTRODUCTION

Although the related risk of vascular necrosis due to filler injection is low, the outcomes can be severe when they occur. This systematic review aims to report the occurrence and treatment of vascular necrosis due to filler injection.

MATERIALS AND METHODS

The systematic review was performed according to PRISMA guidelines.

RESULTS

The results showed the most used treatment is a combination of pharmacologic therapy and hyaluronidase application, which is efficacy when applied in the first 4 h. In addition, even though management recommendations are available in literature, proper guidelines are unavailable due to the low number of complications occurrence.

CONCLUSION

Clinical and high-quality studies on treatment and management of filler injection combination are necessary to provide scientific evidence on what to do in case of vascular complication occurrence.

Recurrent Periorbital Edema Associated With Retained Foreign Body After Filler Injection

A 34-year-old man presented with recurrent bilateral periorbital swelling and pain for 16 years after receiving facial fillers of an unknown substance in a hotel room from a stranger claiming to work in a medical office. Exam demonstrated a firm, mildly tender nodule along the right upper cheek. Imaging revealed a tubular hyperdensity in the right premaxillary soft tissues. Lower eyelid and upper cheek dissection resulted in retrieval of a tubular metallic foreign body consistent with a needle. Histopathology of surrounding tissue demonstrated iron deposition with granulomatous inflammation. Periocular fillers are a common aesthetic procedure. Although generally well-tolerated, complications include inflammatory reactions, infection, necrosis, and vision loss. This case highlights retention of a metallic foreign body, a complication of filler injection that has not been previously reported, emphasizing the importance of careful injection technique by licensed professionals and imaging and surgical exploration if a foreign body is suspected.

Delayed Complications following Dermal Filler for Tear Trough Augmentation: A Systematic Review

Tear trough deformity is a popular target for the treatment with filler injections. The side effects are generally mild and transient. However, delayed complications may occur. We aim to perform a thorough systematic review of the published literature related to delayed complications after tear trough filler injections. A search of published literature was conducted in accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines in June 2021 and included PubMed, ScienceDirect, and Embase databases. The Medical Subject Headings (MeSH) terms used included the following terms: delayed complications, nodules, granulomas, swelling, discoloration, dermal filler, hyaluronic acid (HA), polyacrylamide, calcium hydroxyapatite (CaHA), poly-L-lactic acid (PLLA), eyelid, periorbital, periocular, and tear trough. Twenty-eight articles consisting of 52 individual cases were included in the final analysis. 98% (51/52) of patients were female and had an average age of 48.3 years. HA was the most reported product (71.2%, 37/52), followed by PLLA (4/52, 7.7%), and CaHA (4/52, 7.7%). The most common delayed complication with any dermal filler was swelling (42.3%, 22/52) followed by lumps or nodules (25.0%, 13/52). Xanthelasma-like reaction (17.3%, 9/52), migration (7.7%, 4/52), discoloration (3%, 3/52) also occurred. The average time of onset of any complication was 16.8 months with xanthelasma-like reaction appearing soonest (mean: 10 months) and discoloration appearing latest (mean: 52 months). Most swelling cases were caused by HA. Semi-permanent fillers such as PMMA and synthetic fillers such as PLLA were more likely to be associated with lumps and nodules than other complications. It is important that clinicians who perform tear trough augmentation with dermal fillers have a thorough understanding of the risks of the procedure to diagnose and manage them promptly as well as provide patients with accurate information regarding the potential adverse effects.

Delayed Inflammatory Reactions to Hyaluronic Acid Fillers: A Literature Review and Proposed Treatment Algorithm

Background and Objectives

There is a wide diversity of opinions regarding the management of delayed inflammatory reactions (DIRs) secondary to hyaluronic acid (HA)-based fillers. The plethora of approaches has led the authors to conduct a review regarding management and treatment of DIRs as well as establish therapeutic guidelines for this purpose.

Materials and Methods

A review of the literature was performed through databases such as PubMed using keywords including HA-fillers and complications, delayed HA filler sequelae and therapy, soft tissue and dermal filler reactions and management. Additionally, a survey comprised of questions regarding the management and treatment of DIRs was sent to 18 physicians highly experienced with soft-tissue filler injections in 10 countries. Their answers and recommendations were analyzed and debated amongst these panelists.

Results

Sixteen panelists favored antibiotic therapy as first-line treatment for DIRs, specifically dual antibiotic therapy consisting of a fluoroquinolone along with a tetracycline or macrolide for a period of 3-6 weeks. The majority refrained from the use of intralesional (IL) or systemic steroids except in the case of disfiguring or recalcitrant reactions. IL hyaluronidase was recommended by 13 panelists; however, some preferred a watchful waiting approach for a period of 48 hours to 2 weeks prior to IL hyaluronidase, and in cases where antibiotics did not lead to improvement.

Conclusion

A consensus was reached and summarized to propose a clear, easy-to-follow, stepwise algorithm for the treatment of DIRs.

Management Patterns of Delayed Inflammatory Reactions to Hyaluronic Acid Dermal Fillers: An Online Survey in Israel

BACKGROUND

Over the past few decades, soft tissue augmentation is ever-increasing, specifically hyaluronic acid (HA)-based filler injections. As the number of these procedures have risen, so have the adverse reactions. Delayed-type inflammatory reactions (DIRs) secondary to tissue fillers are typically classified according to the time of appearance post-procedure and have various presentations including nodules, abscesses, edema, and discoloration. Currently, the treatment of these complications varies among physicians.

OBJECTIVE

The aim of this study was to assess the knowledge and experience of practitioners in Israel who inject HA-based tissue fillers with respect to the management of late-onset procedural complications.

MATERIALS AND METHODS

A survey regarding management and treatment of late-onset inflammatory reactions was sent to 1120 physicians and dentists in Israel who practice tissue filler injections.

RESULTS

Three hundred thirty-four out of the 1120 practitioners replied to the questionnaire. The majority of respondents were dentists (group A) comprising 31% of all respondents. Group B accounted for 31% of injectors and consisted of dermatologists (19%) and plastic surgeons (12%), and group C (38%) accounted for all other practitioners; 48.2% of all injectors indicated that they have not previously encountered a DIR, whereas 11.4% responded that they have encountered more than 5 DIRs. In order to assess treatment management, we presented the injectors with a simulatory case of a woman with a late-onset complication. Most injectors referred the patient to the emergency department. When asked to establish a treatment plan, the majority of practitioners prescribed short-term oral steroids, ie, prednisone (35.3%). A limited number of patients were treated with intra-lesional hyaluronidase (31.4%) injection as only 34% of injectors kept hyaluronidase at their clinic.

CONCLUSION

The varied approach regarding the management of delayed type reactions to HA-based filler injections, reflected in our study, illustrates the existing ambivalence in the current literature regarding the management and therapy of late-onset complications.

Long-term outcomes of surgically removed migrated polyalkylimide (bio-alcamid) filler to the periorbital area

Purpose

To report the long-term follow-up results after surgical excision of migrated Bio-Alcamid fillers to the Periorbita area.

Methods

A retrospective case series of all patients who underwent surgical removal of migrated Bio-Alcamid fillers to the Periorbita area with minimal follow-up of 1 year from January 2009 to January 2018 was done.

Results

16 female patients (24–52 y) presented with an upper or lower eyelid swelling 3–7 years following a filler injection in the nasal bridge, temporal or malar area. All patients had surgical excision of a granulomatous mass ranging in size from 1–3.5 cm. The histopathology report revealed a giant cell reaction in all patients. Follow–up periods ranged from 1 to 8 years. One patient developed lid retraction and another had recurrence 3 years later; the remaining had an unremarkable course.

Conclusions

Filler migration is one of the potential complications associated with Bio-Alcamid soft tissue injection. It is important for all physicians to assess nodules/masses/swelling in the facial area to be aware that soft tissue fillers may migrate to a location away from their intended site of injection years after the injection. Patients undergoing surgical excision tend to have favorable overall long-term outcomes in terms of aesthetics and incidence of recurrence.
