[BACKGROUND] Hyaluronic acid (HA) filler injections are widely known to be safe; however, they cause rare and severe complications such as visual loss. No standardized treatment protocol has been established because of the rarity and hetero…

[BACKGROUND] Hyaluronic acid (HA) filler-induced vascular occlusion is a serious complication in aesthetic medicine, yet the microvascular behavior of HA gels under physiologically relevant flow conditions remains poorly characterized. [OB…

Severely ptotic and flat breasts pose significant reconstructive and aesthetic challenges due to poor skin elasticity and attenuated support structures, which limit the stability of upper pole projection. Augmentation mastopexy using implan…

[BACKGROUND] Traditional intraoperative flap assessments like capillary refill and distal bleeding can provide insight on flap viability and circulation; however, it is difficult to assess the cause of the vascular compromise or detect earl…

: Microsurgical breast reconstruction is advancing rapidly with the integration of innovative technologies that enhance surgical precision, safety, and outcomes. This narrative review highlights recent developments across four key phases: f…

The "July Effect" refers to the potential increase in adverse outcomes associated with the annual turnover of medical trainees, although its impact on surgical fields remains uncertain. Additionally, few studies have examined whether the op…

[BACKGROUND] Complex lower limb injuries involving soft tissue defects, fractures, and vascular compromise present significant reconstructive challenges. Free tissue transfer is often the gold standard for reconstruction; however, reverse s…

[BACKGROUND] Reconstruction of tongue defects following oncologic resection remains a clinical challenge, requiring both functional and aesthetic restoration. Lateral arm free flap (LAFF) provides a thin and pliable option with minimal dono…

Free tissue transfer has become the gold standard for reconstructing complex head and neck defects, achieving success rates exceeding 95% in experienced centers. Despite these advances, vascular compromise remains the leading cause of flap …

[BACKGROUND] Post-radiation fibrosis and vascular compromise significantly complicate elective breast surgeries in previously irradiated patients, despite a high incidence of post-treatment asymmetry and macromastia. This study evaluates co…

[OBJECTIVE] This study aims to evaluate the salvage rates of re-explored free flaps in extremity reconstruction, focusing on the timing of re-exploration, types of vascular compromise, and related factors that affect outcomes. [METHODS] A …

[PURPOSE] This study aimed to design a novel pH sensor for free flap monitoring and to evaluate its efficacy in a preliminary animal model, with the goal of supporting earlier detection of perfusion changes. [MATERIALS AND METHODS] The stu…

The 21st-century evolution of hyaluronic acid fillers has brought a diversity of novel aesthetic applications, ranging from static bony augmentation and volume correction to dynamic rhytid effacement and skin revitalization. This rapid adva…

Hyaluronic acid (HA) is a widely used dermal filler in cosmetic procedures due to its biocompatibility and ability to provide volume and hydration to the skin. Despite its popularity and general safety, adverse reactions can occur, necessit…

Mucormycosis is a rare but potentially fatal opportunistic fungal infection with high morbidity and mortality rates despite aggressive treatment. Rhinocerebral mucormycosis represents the most common form, requiring prompt recognition and m…

Vascular complications after facial filling with hyaluronic acid/poly-l-lactic acid (HA/PLLA) composite fillers are rare. Herein, the authors report a case of vascular occlusion after nose and nasolabial fold augmentation with HA/PLLA that …

The radial forearm free flap (RFFF) remains a cornerstone in head and neck reconstruction. Despite various venous anastomotic techniques, including single and dual anastomoses, venous compromise continues to be the leading cause of free fla…

[BACKGROUND] Early detection of vascular compromise is pivotal for successful microvascular flap reconstruction, as tissue necrosis can begin within 6 to 8 hours of circulatory impairment. Although conventional monitoring relies on subjecti…

Microvascular free-flap transfer is a widely used technique for reconstructing complex tissue defects. While early postoperative flap survival depends on intact vascular anastomoses, neovascularization may contribute to long-term viability.…

[BACKGROUND] Hyaluronic acid (HA) fillers are a key treatment in the augmentation and rejuvenation of the lips. The novel Multi Vector (MV) Lip technique has been developed using specific injection vectors in geometric forms to shape the li…
