Article Abstract
Objective: To study the anatomy of the cutaneous branch (CB) of supratrochlear artery and its relevance to the design of frontal flap in nasal reconstruction.
Methods: 10 fresh cadavers were dissected to study the position and course of the CB of supratrochlear artery (supraorbital rim and facial midline as landmark). The communication between the CB and supraorbital artery was also studied. 5 cases of ultra-thin frontal flaps and 11 cases of bi-flap( cutaneous flap and muscular flap) were designed on anatomic basis. The survival rate of flap, the stability and aesthetic appearance of the reconstructed nose were followed up.
Results: The supratrochlear artery gave off constant CB (1.18 +/- 0.36) cm from upper orbital rim and (1.35 +/- 0.34) cm from the midline of face. The CB passed in a subcutaneous plane and communicated with the bilateral muscular branch, CB of the opposite side and bilateral supraorbital artery. The supratrochlear artery only had CB with no muscular branch in 3 cases. All the flaps survived completely except one with blister on the nose tip which healed spontaneously. The postoperative aesthetic appearance was very satisfactory.
Conclusions: The supratrochlear artery has constant CB. The frontal ultra-thin flap pedicled with the CB can improve the therapeutic effect of nasal reconstruction.

Background: The rapid growth of aesthetic medicine has led to an increased demand for non-surgical cosmetic procedures in the frontal region of the face. However, alongside this rise in popularity, there is a growing awareness of the potential complications associated with these procedures especially connected with fillers. The intricate vascular anatomy of the forehead, specifically the supratrochlear (STA) and supraorbital (SOA) arteries, poses significant risks if not thoroughly understood.

Glabellar filler injections are a popular non-surgical approach to address depressions and wrinkles caused by aging, muscle activity, and soft tissue loss. An anatomy-based technique emphasizes understanding the complex structure of the glabellar region, including the corrugator supercilii and procerus muscles, and the superficial vascular pathways, such as the supratrochlear and supraorbital arteries. Effective treatment involves precise filler placement, often combined with botulinum toxin to address both volume loss and dynamic wrinkles.

Hyaluronic acid (HA) non-surgical procedures are increasingly popular, with approximately 5.6 million performed annually by plastic surgeons worldwide. These treatments effectively address signs of aging in the forehead and nasofrontal areas but come with risks such as bruising, swelling, infections, inflammation, granulomas, skin necrosis, and vascular obstructions.

Background: Despite the advancement of reconstructive surgical techniques, facial defect reconstruction has been always very challenging, aesthetic satisfaction has often been difficult to achieve due to the unique characteristics and complexity of the facial tissue. There have been various options regarding reconstruction and compensation of soft tissue loss all over the body rather than the face. Regardless of whether skin grafts, local flaps, and free flaps were used in the reconstruction process, each of them has its limitations.

Article Synopsis
- - Forehead flatness is common in Korean people, and injecting hyaluronic acid (HA) filler is a simple way to create volume, but there are no clear guidelines for this process, making knowledge of blood vessel anatomy essential to prevent complications
- - The study involved using Doppler ultrasound to map facial arteries in 34 patients before HA injections to establish proper guidelines for safe forehead augmentation
- - The results showed that the ultrasound technique allowed the authors to successfully identify and avoid main blood vessels, leading to no vascular complications in the patients after receiving an average of 2.85 mL of HA filler
