“…Knowledge of anastomoses of the ZOA with surrounding arteries should be considered when performing filler injections in order to avoid occluding the vessel. The relationships between the ZOA and surrounding arterial structures were reported 17–19 . It was found that there were arterial networks running through different layers located in the temporal region 17 .…”

“…[17][18][19] It was found that there were arterial networks running through different layers located in the temporal region. 17 The networks were formed by anastomosis of the branches of the ZOA with the transverse facial artery, or the frontal branch of the STA, and the supratrochlear or supraorbital artery of the ophthalmic artery. 18 Among the branches of STA, the frontal branch has effective anastomoses with the forehead branches of the ophthalmic artery, which can occur ocular complications.…”

The zygomatico-orbital artery (ZOA) originating from the superficial temporal artery and supplying the lower temporal region superficially has been reported. Previous studies of this artery have used definitions that are too ambiguous for the results to be directly adapted to clinical practice, including since they have resulted in marked variations in the reported incidence ofthe artery. This study dissected 193 hemifaces of 123 fixed human cadavers aged 36 to 102 years (119 males and 74 females). The authors investigated the ZOA based on the following definition: (1) it originates from the superficial temporal artery, (2) it runs mostly above the zygomatic arch, and (3) it terminates below the superior border of the orbicularis oculi muscle. The incidence of the ZOA was 22.8% (44 cases of 193 sides), and its mean diameter was 1.1 mm. The meanvertical distances from the superior borderofthe zygomatic arch to the artery were 29.6, 17.8, and 2.9 mm at the jugale, zygion, and the origin of the ZOA, respectively. An accurate definition of the ZOA and accurate knowledge of its incidence and course could be important for clinicians to avoid unintentional complications in clinical practice.

“…Moreover, based on computed tomography scans from 40 cadaveric hemifaces, Zhao et al found that the TFA has a great role in vascularization of the lateral orbit and malar plexus. In 23.0% of cases, the TFA was a trunk artery for lateral orbit and malar plexus, and in another 31.0%, this plexus was equally vascularized by the TFA, zygomatic-orbital artery, and premasseteric branch of the facial artery [17].…”

The transverse facial artery anatomy: Implications for plastic surgery procedures

et al. 2019

BackgroundThe transverse facial artery (TFA) perfuses the lateral face. Knowledge of topographical anatomy of the lateral face is crucial for safe procedural performance in aesthetic and plastic surgery, especially the face lift flap and face transplant. The aim of the present study was to assess detailed TFA morphometrical features.Patients and methodsOne-hundred computed tomography head angiographies were analyzed. TFA numbers and origins were recorded bilaterally (200 cases). TFA diameters and lengths in addition to their positions in relation to neighboring vessels and the zygomatic arches were measured.ResultsTFA was present in 96% of cases (192/200, left = 97, right = 95). A single TFA was present in 95.3% and double TFAs were present in 4.7% of cases. In 91.7%, the TFA originated from the superficial temporal artery, and in 3.1%, it originated from the external carotid artery. One left TFA originated from the maxillary artery. The TFA was significantly longer on the right than on the left side (56.6±26.0 versus 47.3±22.2 mm; p = 0.03). The TFA mean diameter was 1.0±0.4 mm (range: 0.4–2.2 mm) with no difference between face sides. TFA length correlated with its diameter (r = 0.46, p <0.05). The TFA always originated below the zygomatic arch, and it should be found in the 8.8 mm wide area beginning 17.0mm below the lower border of the zygomatic arch.ConclusionsThe TFA has a significant role in lateral face vascularization, and absence of this vessel is very uncommon.

“…To date, a number of anatomical studies regarding the vessels in the maxillofacial area have been conducted using CT. For example, Zhao et al (2019) injected contrast dye into the external carotid artery of cadavers and analyzed the FA and its premasseteric branch with reconstructed three-dimensional CT. Cong et al (2021) focused on the deviated FA for rejuvenation non-surgical procedures. Despite the warning by oral surgeons that iatrogenic injury of the FA can be caused by oral surgical procedures (Marco de Lucas et al, 2008;Pukenas et al, 2012), no previous research has attempted to localize the FA and other related vessels in relation to MTM surgery.…”

The potential for facial artery injury during mandibular third molar extraction. An anatomical study using contrast‐enhanced computed tomography

et al. 2021

View full text Add to dashboard Cite

The purpose of this study was to evaluate the risk of injury to the facial (FA) and related arteries during mandibular third molar (MTM) extraction using contrastenhanced computed tomography (CE-CT). CE-CT images of the MTM region were retrospectively reviewed. The area of the MTM was equally divided into three zones in the coronal images from mesial to distal, that is, zone 1, zone 2, and zone 3. The FA, submental artery (SMA), and sublingual artery (SLA) were identified. The distance from the mandible to FA, SMA, and SLA and the diameter of the FA, SMA, and SLA was measured in three zones, respectively. The thickness of the facial soft tissues and width of the mandible were measured at their maximum. The mean distance from the FA to the buccal cortical bone in zone 1, zone 2 and zone 3 was 2.24 mm, 2.39 mm and 1.67 mm, respectively. The SMA and SLA were found to be distal to the mandible. The mean diameter of the FA was 1.26 mm in males and 1.04 mm in females, respectively (p < 0.0001). The distance between the FA and buccal cortical bone of the mandible, and the patients' weight showed moderate correlation in zones 1 and 2. Based on our findings, the FA can be damaged if the surgical invasion reaches the facial soft tissues during MTM surgery. The patients' weight might be a good predictor for FA injury when CE-CT is not available.

Three-Dimensional Computed Tomographic Study on the Periorbital Branches of the Ophthalmic Artery: Arterial Variations and Clinical Relevance

Abstract: Postmortem 3D CT can map periorbital arterial variations. The branching pattern of the ophthalmic artery, the ophthalmic angiosome in the forehead, and the distribution of the lateral orbit and malar plexus were identified at high resolution to guide clinical practice.
