Anatomical knowledge of zygomatico-buccal plexus in a cadaveric study.

The details of the facial nerve pattern were clearly explained in the parotid gland (PG), lateral area of the face, and periorbital areas to prevent the unexpected outcome of medical intervention. However, it remains unclear whether information about the zygomatico-buccal plexus (ZBP) in the masseteric and buccal regions. Therefore, this study aimed to help clinicians avoid this ZBP injury by predicting their common location.

Lower Nose Arterial Plexus and Implications for Safe Filler Injections.

Background: The lower nose has abundant blood supply; however, nasal tip necrosis still occurs following filler injections. This study revealed the complicated pattern of the arterial supply of the lower nose.

Methods: The arterial pattern of the lower nose was studied in 40 cadavers using conventional dissections and translucent modified Sihler staining.

The Crest Injection Technique for Glabellar Line Correction and the Paracentral Artery.

The glabella is a zone that carries a high risk of blindness after performing filler injections. The arteries beneath the glabellar lines were investigated by meticulous dissections in 30 geriatric embalmed cadavers with latex injections into the arterial system. The results showed that the supratrochlear artery, a direct branch of the ophthalmic artery, ascended from the muscular layer of the medial eyebrow along the medial canthal vertical line of the intercanthal vertical zone (53 in 60 hemifaces, or 88%).

Anatomical Study of the Dorsal Nasal Artery to Prevent Visual Complications during Dorsal Nasal Augmentation.

Dorsal nasal augmentation is a common injection associated with ocular complications. Digital compressions on both sides of the nose are recommended during injection. Considering the reported incidences of visual complications, this preventive technique may need an adjustment for more effectiveness to prevent blindness.

Achieving the Most Effective Hanging Points at the Lower End of the Face for Thread Lifting: Quantitative Measurement of Tissue Resistance in Different Facial Layers.

The thread lift procedure is a minimally invasive alternative to facelift surgery. The hanging point, which the terminal end of the thread is hooked into, is an important component. If it is loose and cannot stabilize the passage when the inserted thread is pulled, the lifting effect will fail.

Anatomical and Ultrasonography-Based Investigation to Localize the Arteries on the Central Forehead Region During the Glabellar Augmentation Procedure.

Glabellar augmentation is one of the most popular cosmetic procedures but can entail severe complications caused by inadvertent intravascular injection of filler. Nevertheless, few studies have investigated the arteries on the glabellar and central forehead regions. The aim of this study was to correlate the topography and location of the arteries in this area with anatomical landmarks to propose a safety guideline.

The Feasibility Determination of Risky Severe Complications of Arterial Vasculature Regarding the Filler Injection Sites at the Tear Trough.

Background: The tear trough is a significant sign of periorbital aging and has usually been corrected with filler injection. However, the arterial supply surrounding the tear trough could be inadvertently injured during injection; therefore, this study aimed to evaluate the nearest arterial locations related to the tear trough and investigate the possibility of severe complications following filler injection.

Methods: Thirty hemifaces of 15 Thai embalmed cadavers were used in this study.

Safe Planes for Injection Rhinoplasty: A Histological Analysis of Midline Longitudinal Sections of the Asian Nose.

Background: Dorsal nasal augmentation is an essential part of injection rhinoplasty on the Asian nose. Aesthetic physicians require detailed knowledge of the nasal anatomy to accurately and safely inject filler.

Methods: One hundred and thirty-five histological cross sections were examined from 45 longitudinal strips of soft tissue harvested from the midline of the nose, beginning from the glabella to the nasal tip.
