The aim of the present study was to examine the number and location of the foramen spinosum (FS) in 3D-CT images. Methods: The study was retrospectively conducted on 3D-CT images of 177 adults. Firstly, the transverse section passing through the upper edge of the orbit, extending parallel to the Frankfurt plane was chosen. Then, the x and y-axes were determined on that transverse section. The coordinates, number, and location of the FS with respect to the foramen ovale (FO) were identified accordingly on x and y-axes. Results: While 1 FS was present in 90.96% of a total of 354 sides of 177 heads, there were 2 FS and 3 FS in 8.76% and 0.28% of the sides, respectively. The FS was located posterolaterally in 97.68%, posteriorly in 2.06%, and laterally in 0.26% with respect to the FO. In terms of FS coordinates, there was no statistically significant difference between gender and sides in the distance of the FS to the x-axis, but there was a statistically significant difference between gender and sides in the distance of the FS to the y-axis. Conclusion: Evaluation of the number of the FS and its location would help identifying and preserving neighbouring neurovascular structures during surgical interventions directed to the middle cranial fossa.","PeriodicalId":91999,"journal":{"name":"Anatomy","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90774989","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Their management most often requires regional or free flaps. The perforator flap based on the deltoid branch of the thoracoacromial artery (TAA) may be a good solution for these indications. The objective of this work is to propose anatomical landmarks to raise perforator flaps pedicled on the deltoid branch of the TAA. Methods: We carried out dissection of 24 perforator flaps based on the deltoid branch of the TAA, in body donor specimens preserved in a glycerin-rich, formalin-free solution. The TAA was first injected with methylene blue. The vascular territory, location of perforators relative to known landmarks, along with the flap’s potential amplitude and arc of rotation were studied. Results: The main perforating arteries of the flap were located in the middle of the deltopectoral groove, often surrounded by adipose tissue in 18 out of 24 dissections. In 22 out of 24 dissections, there were at least 2 perforator arteries originating from the deltoid branch. The average diameter of the perforator arteries was 1 mm. The flap’s amplitude of movement made it possible to reach in all cases the lateral triangle of the neck and the anterolateral cervical region. Conclusion: The thoracoacromial artery has already been used for perforator flaps. However, the individualization of its deltoid branch offers to practitioners new surgical options. This anatomical study of the perforator flap based on the deltoid branch of the TAA made it possible to review the anatomical bases for the raising of this flap, and to fix useful landmarks for the surgeon in order to propose an easily feasible surgical technique.","PeriodicalId":91999,"journal":{"name":"Anatomy","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85868669","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Plastinates are easy to handle and can facilitate the learning of complex anatomical structures. Therefore, we aimed to evaluate the contribution of plastinates to teaching complex anatomy of the heart. Methods: Standard S10 technique was used for heart plastination by fixation, dehydration, impregnation and curing stages. Ninety volunteer first-year medicine students at Akdeniz University, who did not take cardiovascular system anatomy lectures yet, were included. Formalin-fixed heart specimens were used in the lecture of group 1; both formalin-fixed heart specimens and heart plastinates were used in the lecture of group 2. After the lecture, a 10-question exam was administered. Statistical significance between the scores of the two groups was tested with one sample t-test, and post hoc Tukey test was used for multiple comparisons. Results: The pre-test scores of the groups were compared with the scores obtained after the 2 hours of lecture (p=0.002, p<0.05). The test scores of both groups increased significantly after the lecture (p<0.05). The post-test scores of group 2 were significantly higher than group 1 (p= 0.047, p<0.05). The average test scores of those trained with formalin-fixed specimens increased from 23.78±1.94 to 48.22±3.19 (p<0.05). Students gave positive feedback about heart plastinates, and they stated that their rising interest in the anatomy lecture due to the odourless, disinfected and reusable materials. Conclusion: In conclusion, besides being cost-effective, healthy, long lasting and easy to maintain materials, plastinates are useful tools to teach complex anatomical structures.","PeriodicalId":91999,"journal":{"name":"Anatomy","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77430704","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Detailed anatomical knowledge of the nasolacrimal duct is crucial for physicians to understand the etiology of the obstructions, to plan ideal management option and to reduce unexpected iatrogenic injuries during surgeries. The aim of this study was to investigate morphometric properties of the nasolacrimal duct on computed tomography images. Methods: Three-dimensional computed tomography (3D-CT) of 142 adults (65 females, 77 males) were retrospectively evaluated. Antero-posterior cranial diameter, antero-posterior and transverse diameters and vertical angle of the nasolacrimal duct, distance between distal end of the nasolacrimal duct to anterior surface of the maxilla were measured and the differences evaluated statistically between right and left sides and among females and males and among different ages. All measurements were done using Osirix-Lite version 9 software. Results: None of the morphometric parameters of the nasolacrimal duct showed significant differences between right and left sides. Antero-posterior cranium and transverse diameter of the nasolacrimal duct were longer in men than women. Conclusion: Determining to morphometric properties of the nasolacrimal canal has advantages for understanding the etiology of the NLD obstructions, deciding the ideal surgical technique and reducing to unexpected injuries during surgeries related with this region.","PeriodicalId":91999,"journal":{"name":"Anatomy","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90658694","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Despite its functional importance throughout the lifespan, little is known about the 3D architecture of trapezius at any post-natal timepoints. Accordingly, the aim of this preliminary cadaveric study was to digitize, quantify, model, and compare the 3D architecture of trapezius at two temporal extremes: infancy and adulthood. Methods: We examined trapezius in two female formalin-embalmed cadavers, aged 6 months and 72 years, respectively. We meticulously dissected each muscle, allowing us to digitize and model the comprehensive muscle architecture in situ at the fiber bundle level. We quantified standard architectural parameters to facilitate comparison between each functional partition of trapezius (i.e., descending, transverse, ascending) and proportionally between the infant and adult specimens. Results: We found markedly different patterns in fiber bundle length range, physiological cross-sectional area, and muscle volume within and between muscles. Notably, the proportional physiological cross-sectional area of the ascending and descending partitions was equal (1:1) in the infant, in contrast to 3:1 in the adult. The transverse partitions were proportionally similar, accounting for over half of the whole muscle physiological cross-sectional area in both specimens. Conclusion: This study provides preliminary insights into infant and adult trapezius architecture at an unparalleled level of detail and precision. The quantifiable architectural differences appear to coincide with functional development-a notion that warrants further investigation in larger samples and with longitudinal approaches.","PeriodicalId":91999,"journal":{"name":"Anatomy","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83932107","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Current research studies have found that vascular supply to the shoulder is variable. However, the incidence of these variations and how they can affect the blood supply to the shoulder region is still under investigation. The aim of this study is to identify possible variation patterns of the circumflex humeral vessels. Methods: A total of 10 shoulders (3 males, 2 females; average age of 68.8 years) were dissected in Anatomy, University of Edinburgh, under the regulation of the Human Tissue (Scotland) Act 2006. Each shoulder was dissected, and tissues were removed to identify the axillary artery and its branches. Results: The anterior and posterior circumflex humeral arteries were observed to arise as single branches from the 3rd part of the axillary artery in 70% (n=7) and 80% (n=8), respectively. In one cadaver, the posterior circumflex humeral artery (PCHA) arose from the subscapular artery in one side (10%, n=1) and from the profunda brachii artery on the contralateral side (10%, n=1). In the remaining 10% (n=1), the anterior circumflex humeral artery (ACHA) was found as a branch from the PCHA, with the latter being a direct branch from the 3rd part of the axillary artery. Conclusion: Knowledge and awareness of these variations is essential to not only suspect, diagnose and treat possible complications of common fractures and dislocations in the region, but also to prevent iatrogenic injury.","PeriodicalId":91999,"journal":{"name":"Anatomy","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2020-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80373408","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
