The facial artery (FA) is the main artery supplying the anterior face, making this artery a very important structure to consider while performing plastic and reconstructive procedures. The literature shows discrepancies in anatomical classifications and the frequency of occurrence of individual variations. Therefore, the goal of this meta‐analysis is to provide surgeons with helpful knowledge about the variety of the termination of FA. Articles with data about the termination of the FA were found in major online medical databases such as PubMed, Scopus, Embase, Web Of Science, and Cochrane Library. A total of 1346 articles were initially evaluated by two independent reviewers. Out of those, 24 articles matched the required criteria, and were used in this meta‐analysis. A total of 2119 studied FAs were included in this study. The FA termination patterns were divided into five previously classified types. The data show that the FA terminates most frequently as the lateral nasal or angular artery with the prevalence for this group being 69.81% (95% confidence interval [CI]: 59.83%–78.94%). Authors believe that this is the most accurate and up to date study regarding termination patterns and the prevalence of the FA. The results of this meta‐analysis could provide a helpful tool for surgeons preforming plastic and cosmetic procedures, especially when injecting dermal fillers or choosing and preforming facial flaps. Detailed anatomical knowledge about the FA may prevent potential surgical complications.
The deep brachial artery (DBA) is the first and largest branch of the brachial artery. Multiple variations of the DBA's origin, termination, and diameter have been reported in the literature. Major online medical databases such as PubMed, Scopus, Embase, Web of Science, and Google Scholar were searched in order to find all studies considering origin variations and the diameter of the DBA. The prevalence of the DBA originating directly from the axillary or brachial artery was shown to be 92.87%. DBA originating indirectly from the axillary or brachial artery, as a common trunk with other arteries, was found to be 7.13%. The mean diameter of the DBA was shown to be 2.05 mm. The authors of the present study believe that this is the most accurate and up-to-date meta-analysis considering origin patterns and the diameter of the DBA. Additionally, this study contains a comprehensive literature review in which current detailed anatomical knowledge concerning the DBA was gathered. The results of this study could provide a helpful tool for physicians, especially surgeons, dealing with an upper limb in their daily practice.

The number of studies on the anatomy of the costocervical trunk (CCT) is scarce, and the actual prevalence of this structure is unknown. Therefore, the authors of the present study would like to propose a set of four types of CCT, which were created based on observations of computed tomography angiographies (75 CCTs). A retrospective study was conducted to establish variations and the morphometric properties of the CCT. The results of 55 consecutive patients who underwent neck and thoracic computed tomography angiography (CTA) were analyzed in March 2022.The analysis was performed on a total of 75 CCTs. Of these, 32 were from women (42.7%) and 43 were from men (57.3%). Branching variations of each CCT were thoroughly analyzed. A classification of the branching pattern of the CCTs was made and consisted of four types. In the present study, the variety of branching and morphology of CCT was analyzed, proposing its novel classification based on the four most frequently observed types. Type 1 was the most prevalent (76.1%), having a similar origin and branching pattern as described in the major anatomical books. CCT was found to be absent in 23.94% of the cases, making it a somewhat less consistent branch of the SA. Understanding the variability of the anatomy of the CCT can be a great tool for physicians performing endovascular procedures in the cervical region.
Purpose The thoracoacromial trunk (TAT) originates from the second part of the axillary artery and curls around the superomedial border of the pectoralis minor, subsequently piercing the costocoracoid membrane. Knowledge about the location, morphology, and variations of the TAT and its branches is of great surgical importance due to its frequent use in various reconstructive flaps. Methods A retrospective study was conducted to establish anatomical variations, their prevalence, and morphometric data on TAT and its branches. The results of 55 consecutive patients who underwent neck and thoracic computed tomography angiography were analyzed. A qualitative evaluation of each TAT was performed. Results A total of 15 morphologically different TAT variants were initially established. The median length of the TAT was set at 7.74 mm (LQ 3.50; HQ 13.65). The median maximum diameter of the TAT was established at 4.19 mm (LQ 3.86; HQ 4.90). The median TAT ostial area was set to 13.97 mm (LQ 11.70; HQ 18.86). To create a heat map of the most frequent location of the TAT, measurements of the relating structures were made. Conclusion In this study, the morphology and variations of the branching pattern of the TAT were presented, proposing a new classification system based on the four most commonly prevalent types. The prevalence of each branch arising directly from the TAT was also analyzed. It is hoped that the results of the present anatomical analysis can help to minimize potential complications when performing plastic or reconstructive procedures associated with TAT.
Purpose The synovial plica of the elbow is a fold of synovial tissue, which is said to be a remnant of the embryonic septa of normal articular development and is located around the radiocapitellar joint. The objective of the present study was to provide morphometric properties of the synovial plica of the elbow and its relation to surrounding structures in asymptomatic patients. Methods A retrospective study was conducted to establish the morphometric characteristics of the synovial plica of the elbow. The results of 216 consecutive patients, who for different reasons during the five year period of time underwent magnetic resonance imaging (MRI) of an elbow, were analyzed. Results Plica was found in a total of 161 of 216 elbows (74.5%). The mean width of the plica was set to be 3.00 mm (SD: 1.39). The mean length of the plica was established at 2.91 mm (SD: 1.13). An analysis of sexual dimorphism was also included. Potential correlations were analyzed for each of the categories and age. Conclusions The synovial plica of the elbow is a clinically relevant anatomical structure. Analyzing the morphometric parameters of the synovial plica is necessary to properly evaluate synovial plica syndrome, which can commonly be confused with other sources of lateral elbow pain such as tennis elbow, oppression of the radial and/or posterior interosseous nerve, or snapping of the triceps tendon. The authors suggest that the thickness of the plica may not be the golden diagnostic feature as there are no statistically significant differences in this parameter between symptomatic and asymptomatic patients. A precise and accurate diagnosis of synovial fold syndrome and/or differentiation from other sources of lateral elbow pain must be performed, as the surgical treatment, even if performed properly, will be unsuccessful because of a misdiagnosed source of pain.
