    Trends and Scientific Evolution in Endovascular Aneurysm Repair (EVAR) Research: A Comprehensive Bibliometric Study Using Vosviewer
    (Sage Publications Inc, 2026) Sever, Sinem Nur; Oktem, Hale; Jamil, Yusuf; Pelin, Can
    Background: Endovascular aneurysm repair (EVAR) has become a standard treatment for abdominal aortic aneurysms. However, the evolution of EVAR research and its global landscape remain underexplored. This bibliometric analysis aims to map publication trends, identify key contributors, and analyze thematic shifts in EVAR literature over the past three decades.Methods: Data were collected from the Web of Science Core Collection (SCIE) in May 2025. A total of 4264 original research articles on EVAR were analyzed using VOSviewer for co-authorship, co-citation, and keyword co-occurrence mapping. Citation trends, geographical distribution, and institutional contributions were also assessed.Results: Research on EVAR showed steady growth, with a peak of 295 publications in 2024. The United States contributed the largest share (33.02%) of publications. Prolific authors such as Schermerhorn and Verhagen, affiliated with leading institutions like Harvard University, played a pivotal role in advancing the field. Keyword analysis revealed a shift from technical terms (e.g., "stent graft") to clinical outcomes (e.g., "reintervention") over time. The integration of artificial intelligence (AI) in EVAR research is emerging as a key focus area.Conclusion: This study highlights the growth and evolving focus of EVAR research, with a notable shift toward patient-centered outcomes. Despite strong contributions from high-income countries, there is a significant gap in research from low-resource settings. Future directions should include addressing gaps in radiation safety, emergency EVAR applications, and exploring AI-driven clinical decision-making for personalized treatments. Complex EVAR research continues expanding, reflecting guideline evolution and advancing practice in anatomically challenging cases.Clinical Impact This bibliometric analysis demonstrates how EVAR has progressed from an emerging minimally invasive technique to a guideline driven standard of care, with a growing emphasis on complex fenestrated and branched procedures. For clinicians, the findings clarify where the evidence base is well established, particularly for standard infrarenal EVAR, and where further caution and innovation are required, including complex anatomies, long term durability, and reintervention risk. By synthesizing influential studies, key guideline milestones, and evolving research themes, this study supports evidence based clinical decision making, improves patient counseling, and reinforces the importance of lifelong surveillance. Its innovation lies in translating three decades of global research into clinically actionable insight.

    Anatomical and Clinical Evaluation of Tympanic Tegmen and Mastoid Bone With Multidetector Computed Tomography
    (Soc Chilena Anatomia, 2023) Sever, Sinem Nur; Cetin, Huseyin; Caliskan, Selma; Akkasoglu, Sinem
    Tegmen level and mastoid bone thickness are important parameters of surgical risk in middle ear and mastoid region surgeries. This retrospective cohort study was conducted to provide a risk classification for the mastoid and middle ear regions. The study population comprised of 300 patients who underwent multidetector computed tomography (MDCT) for various indications. Patients with no pathology that disrupted the structure of the temporal region were included in the study. A risk classification was generated by analyzing the data obtained from mastoid and tympanic tegmen depths and the mastoid bone thickness by MDCT. The mastoid and tympanic tegmen were lower on the right side than on the left. In women, the right-sided mastoid bone thickness and mastoid tegmen were lower, and low-level tympanic and mastoid tegmen on the left and thin right mastoid bones were more common. According to the risk classifications for mastoid and middle ear region surgeries, women demonstrated a higher risk than men. In addition, as the thickness of the mastoid bone increased, the levels of the mastoid and tympanic tegmen increased. The present study provides a proper risk classification that may be helpful for preoperative risk assessment prior to middle ear and mastoid region surgery.

    Scientific Research on the Pineal Gland: a Bibliometric Analysis From Its First Publication
    (Aves, 2024) Şen, Esra; Sever, Sinem Nur; Turhan, Begümhan
    Objective: The bibliometric perspective examines publications using a quantitative way and statistics to analyze them. The purpose of the current study was to perform a comprehensive overview of the research on the pineal gland through bibliometric methods to determine the trends and rare topics related to the gland. Methods: The Web of Science database was used to identify the publications associated with the gland. The literature review exposed a total of 8719 publications. The identified publications were analyzed using the bibliometric approaches (VOSviewer Version 1.6.13). Results: The first studies on the pineal gland were in the 1970s. The most prolific country is the United States (2451). It was seen that most of the articles were published in Journal of Pineal Research. The majority of publications (97.09%) were written in English. The most prolific author is Reiter, Russel J. Moreover, the most prolific institute is the Centre National De La Recherche Scientifique (France). The most popular keywords in the articles were pineal gland, melatonin, circadian rhythm, rat, retina, photoperiod, circadian, aging, serotonin, oxidative stress, and brain. Conclusion: The results indicated the researchers’ interest in the gland and provided quantitative data about the place of the gland in the scientific area. Studies on this subject have tended to increase in recent years. As far as we know, this research is the first bibliometric study to provide a comprehensive analysis of scientific publications with an emphasis on the pineal gland since 1976.

    Bibliometric Analysis of Publications on Stapedius Muscle
    (Pera Yayincilik Hizmetleri, 2024) Sever, Sinem Nur; Sen, Esra; Turhan, Begümhan
    Objective: The clinical importance of the stapedius muscle has been particularly emphasized in several publications. The purpose of this study is to bibliometrically analyze all publications on the stapedius muscle and to determine research trends related to this muscle. Methods: The publications related to the stapedius muscle were identified by the Web of Science database. A total of 548 publications were discovered throughout the literature review. Bibliometric techniques were employed to analyze the identified publications (VOSviewer Version 1.6.13). Results: The first studies were conducted in the 1980s. The highest number of publications related to the stapedius muscle was in 2020 (22 studies), while the lowest was in 1985 (2 studies). Most of the publications (90.11%) were written in English. The USA was the most prolific nation, with John J. Guinan having written the most articles on the stapedius muscle. Harvard University was also the most prolific institution. Conclusion: The findings demonstrated the researchers’ interest in the stapedius muscle and offered quantifiable information regarding the muscle’s position within the scientific domain. Recent years have seen an increase in studies on this topic. To the best of our knowledge, it can be said that this study is the first bibliometric analysis on the stapedius muscle.
