    Investigating impostor syndrome among postgraduate anatomy students
    (Galenos Publishing House, 2025) Ok, Fatma; Karip, Burak; Nteli Chatzioglou, Gkionoul; Temizsoy Korkmaz, Fulya; Yiğit, Mehmet
    Background: Impostor syndrome (IS) is marked by persistent self-doubt and the fear of being perceived as a fraud, even in the presence of clear accomplishments, and it notably affects high-achieving individuals. This study examined IS prevalence and associated factors among postgraduate anatomy students in Türkiye. Materials and Methods: Using the Clance Impostor Phenomenon Scale, 79 participants were surveyed to assess IS levels alongside demographic and psychiatric variables. Results: The results revealed that 39.2% of participants exhibited frequent impostor feelings (FIF) or intense impostor experiences (IIE). Notably, individuals with psychiatric conditions had significantly higher IS levels, with 64.7% classified in the FIF category and 17.6% in IIE, compared to those without psychiatric issues, who predominantly fell into lower IS categories (p<0.05). No statistically significant associations were observed between IS and demographic variables, including gender, marital status, or education level. However, individuals with no income were overrepresented in the IIE category, aligning with findings from studies suggesting a link between socioeconomic status and heightened IS levels. Conclusion: This study underscores the prevalence of IS in postgraduate students within a demanding academic discipline and highlights its association with psychiatric conditions. Increasing awareness of IS, particularly in high-stress, perfectionist professions such as academia, is critical. Such efforts can improve recognition, provide targeted interventions, and mitigate IS’s impact on individual well-being and professional performance.

    Origin-order classification of axillary third-part branching: Donor-based dissection–CTA correlation for surgical planning
    (Springer Nature Link, 2025) Temizsoy Korkmaz, Fulya; Coşkun, Osman; Gürses, İlke Ali; Gayretli, Özcan; Özdemir, Sevim; Öztürk, Adnan; Kale, Ayşin
    Purpose Variations in the branching of the subscapular artery (SSA), anterior circumflex humeral artery (ACHA), and posterior circumflex humeral artery (PCHA) are directly relevant to reconstructive planning with subscapular-system flaps and to humeral-head perfusion in shoulder surgery. Evidence organized around an origin-order–based framework remains limited. We aimed to address this gap by comparing body-donor dissections and computed tomography angiography (CTA) to provide a clinically useful classification and morphometric reference. Methods We performed a two-arm cross-sectional morphometric study: body-donor dissection (28 donors; bilateral, 56 sides) and CTA (25 patients; bilateral, 50 sides). In total, 104 sides were evaluated; 96 were classifiable. Classification used the sequential SSA–ACHA–PCHA origin order and common-trunk presence. Ostial diameters and SSA → CSA distances were measured; the radial nerve (NR)–SSA relationship was assessed in donors. origin_order__five_type_classif… Results In donors, Type-1, -2, -3, and -4 accounted for 36.5%, 32.7%, 23.1%, and 7.7%, respectively; Type-5 was absent. In CTA, Type-1, -4, and -5 comprised 93.2%, 2.3%, and 4.5% (one bilateral case); Types-2/-3 were not observed. Inter-modality comparison showed a longer SSA → CSA distance and smaller TDA/CSA diameters in CTA (all p < 0.001), while the SSA ostial diameter was similar. A posterior NR course relative to the SSA was associated with a longer SSA → CSA distance (p = 0.026). Conclusion An origin-order–based classification, corroborated across dissection and CTA, yields a practical map for (i) single-pedicle harvesting within the subscapular system and chimeric flap design, and (ii) avoiding iatrogenic compromise of humeral-head vascularity during shoulder procedures. Incorporating presurgical CTA mapping of the SSA and its branches may enhance safety where variants (e.g., short/combined trunks, rare Type-5) are suspected.
