... The extrusion force (N) is the force necessary to move the hydrogel through the needle 10,14,[17][18][19] and was measured in a pressure test 13 with the universal testing machine Inspekt Mini 3kN (Hegewald & Peschke MPT GmbH). ...
... The transducer is placed over the medial orbital rim in the horizontal plane, and the medial edge of the transducer is pivoted to the medial canthus. The supratrochlear artery is visualized as it emerges from the supratrochlear foramen [28] (Figure 4). The supratrochlear nerve ( Figure 5) [29] (which originates from the frontal nerve, which itself is a branch of the ophthalmic nerve) and vein may be visualized in addition to the supratrochlear artery. ...
... The impact is most noticeable on the cheeks, whereas the neck and top of the head are less noticeable. This is congruent with human anatomy, as the cheeks are more prone to weight accumulation than the top of the head and neck [Swift et al. 2021]. Despite the fact that this deformation only changes the surface geometry, simply altering skin vertices would result in unnatural deformation and visual artifacts caused by skin and skull collision. ...
... 8,10 Based on these ndings and concepts, a new technique was proposed by Casabona et al to improve volume and to produce a "lifting e ect" through the vector application of hyaluronic acid application in the temporal region. 9,11 The results presented were very satisfactory, with face morphology improvement, increased volume in the temporal region, reduction of periorbital wrinkles, eyebrow tail lifting, malar region repositioning and distally, marionette line reduction. 7 Despite the encouraging results of the hyaluronic acid application in the temporal region, there is a signi cant risk of complications resulting from vascular obstruction due to its high viscosity. ...
... 3 Tseng et al established that aspiration before filler injection can be beneficial if the right product/needle combination is utilized. 4 According to Poiseuille's rheology law, aspirating a filler with a higher viscosity in a longer and thinner needle is more difficult. That is, aspirating pressure and duration must be adjusted according to filler, needle, and syringe properties. ...
... Previous studies usually focused on the supratrochlear artery as the cause of ocular complications following injections at the glabellar frown lines. 4,5 We agree with Koziej et al who suggested that the DPA is the cause of ocular complications following central forehead injections. 6 Lee et al used ultrasound imaging to avoid filler misinjection into the artery traveling deep to the glabellar wrinkles in 41% of the glabellar lines. ...
... The inferior labial artery/vein and the facial artery/vein are important vessels of the lower face ( Figure 1) [22]. Innervation of the lower face is primarily via the mental nerve [14]. ...
... 6 Recent studies on facial anatomy with a focus on morphology and its geometric changes have found that facial aging occurs in a three-dimensional manner-not only by reduced collagen and elastin in the skin, but also reduced super cial and deep fat pads due to bone resorption and ligament laxity; this results in a reduction in overall facial support. 7,8 In this sense, the deepening and visibility of the temporal region is a typical sign of advancing age. ...
... Collectively, these measures are fundamental for achieving safe and natural outcomes for patients. 5,[8][9][10][11] The survey revealed limited awareness of differential immunogenicity between different HA fillers and the relevant influencing factors among practitioners in Asia Pacific despite published evidence. [12][13][14][15][16][17][18] Although practitioners recognized the importance of choosing HA fillers that are less prone to DIRs for treatment, close to half did not perceive high composition of LMW-HA as relating to higher risk of DIRs and half did not seem to be aware of any difference in the risk of DIRs between different HA filler technologies ( Figures 1B, 2 and 3). ...
