[BACKGROUND] The widespread use of hyaluronic acid (HA) dermal fillers has been accompanied by an increase in vascular complications, including ischemia and cutaneous necrosis. Although uncommon, filler-induced vascular compromise represent…

Vascular adverse events associated with hyaluronic acid (HA) dermal fillers are typically interpreted as being of arterial origin, while venous involvement of the lip remains poorly characterized. The aim of this report is to analyze and up…

[BACKGROUND] Non-surgical genioplasty is one of the best choices in cases of chin retrusion, and it represents a solution for the aesthetic amelioration of facial profile. Recent concerns arose about the risk of bone resorption and vascular…

[INTRODUCTION] Nonsurgical rhinoplasty is a widely performed procedure but is still considered high-risk by many clinicians because of the potential for serious and potentially irreversible complications, including vascular compromise. This…

[BACKGROUND] Free flaps require close postoperative monitoring to detect vascular thrombosis at an early stage, which is the main cause of failure. Although clinical examination remains the benchmark, it is subjective. Indocyanine green, a …

[PURPOSE] The use of cosmetic fillers has become increasingly popular. Radiologists and sonographers should be aware of the ultrasonographic characteristics of the most commonly used cosmetic fillers and the sonographic features of their fr…

[BACKGROUND] Free tissue transfer requires meticulous postoperative monitoring to detect vascular occlusion. Although experimental studies have explored the relationship between interstitial glucose levels and tissue perfusion, long-term ev…

The choice between cannulas and needles for dermal filler injection has direct implications for safety, efficacy, and patient experience. This narrative review synthesizes evidence from randomized controlled trials, observational studies, c…

[INTRODUCTION] Aging leads to facial volume loss, particularly in the forehead, resulting in a flat appearance and static wrinkles. Effective forehead rejuvenation aims to restore volume while minimizing risks associated with filler injecti…

[BACKGROUND] Augmentation mastopexy is a complex and technically demanding procedure that addresses breast ptosis and volume deficiency simultaneously. It requires careful planning, precise surgical techniques, and customization to each pat…

Microsurgical free-flap reconstruction has become essential for restoring form and function in pediatric head and neck defects, yet outcome data remain heterogeneous and often limited to technical survival. This single-center retrospective …

[BACKGROUND] Vascular compromise is a serious complication in free-flap surgery for traumatic reconstruction or fracture-related infections, often leading to partial or total flap loss if not detected promptly. We evaluated transcutaneous p…

The facial artery (FA) is the main vascular supply to the anterior face, but it exhibits considerable anatomical variation that impacts surgical planning. We review FA anatomy and variants, examining clinical and radiological data since 201…

The fibula free flap (FFF) is one of the most widely used methods for head and neck bony reconstruction, yet pedicle ossification-though rare-can lead to complications. Although historically considered benign, ossification may cause vascula…

Hyaluronic acid (HA) fillers are widely used for non-surgical facial contouring, but vascular occlusion remains one of the most feared complications due to its potential to cause necrosis, functional impairment, and permanent deformities. C…

[BACKGROUND] Nasolabial folds (NLFs) are a hallmark of facial ageing, and precise correction requires detailed anatomical and vascular mapping. High-resolution ultrasound offers real-time visualisation of soft-tissue layers, filler distribu…

Vascular occlusion is an uncommon but serious complication of hyaluronic acid filler injections. If not recognized and managed early, it can lead to ischemia and even skin necrosis. Timely diagnosis and intervention are therefore crucial to…

Nonsurgical rhinoplasty (NSR) is a minimally invasive alternative to surgical rhinoplasty that uses dermal fillers to enhance nasal aesthetics. When performed by trained injectors, NSR offers rapid correction with relatively low downtime. T…

[BACKGROUND] Filler-induced vascular occlusion remains a rare but serious complication in aesthetic medicine, particularly in the lips, where collateral circulation is limited. Polynucleotide (DOT-PN) is a polynucleotide-based medical devic…

The rising number of Hyaluronic acid (HA) filler applications has led to an increase in the incidence of complications, which can range from undesired aesthetic outcomes to severe vascular occlusion events. Hyaluronidase (Hyal) hydrolyzes H…
