    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.

    Osseous anatomy of the distal radius: A morphometric analysis of external groove and bony ridge
    (Springer Nature Link, 2025) Ok, Fatma; Çelikgün, Beyza; Nteli Chatzioglou, Gkionoul; Ertaş, Ahmet; Coşkun, Osman
    Purpose: This study aimed to investigate the presence and morphological and morphometric characteristics of the distal radius's external groove (EG) and bony ridge, which play a potential role in the pathogenesis and treatment difficulties of De Quervain's tenosynovitis. Methods: The osseous anatomy of the distal radius was analyzed in detail on a total of 103 dry bone specimens (49 left and 54 right) obtained from the Department of Anatomy, Istanbul University, Turkiye. The frequency and morphology of the EG were analyzed. The EGs were categorized as Type 1, Type 2, and Type 3 with two EGs, one EG with depth, and an additional EG without depth, respectively. Finally, flat areas without clear groove boundaries were classified as Type 4. Results: The analyses showed variations in the morphology and dimensions of the EG and bony ridge. A total of 110 EGs were detected in 103 radii examined. Type 1, Type 2, Type 3 and Type 4 EGs were reported in 30 bones (30%), 38 bones (38%), 12 bones (12%) and 23 bones (23%), respectively. The depth of the EG of Type 1 was 0.26 ± 0.23 mm and 0.22 ± 0.16 mm on the lateral and medial sides, respectively. Also, the depth of the Type 2 was calculated as 0.49 ± 0.37 mm. Conclusion: The osseous variations of the distal radius are critical anatomical factors contributing to the pathogenesis of De Quervain's tenosynovitis and difficulties in the treatment process. It is essential to recognize these variations to improve diagnostic accuracy and optimize therapeutic interventions.

    The morphological and morphometric examination of the asterion in terms of surgical approaches to the posterior cranial fossa
    (Pera Yayıncılık, 2025) Coşkun, Osman; Yiğit, Mehmet; Çelikgün, Beyza; Ok, Fatma; Ertaş, Ahmet; Gayretli, Özcan
    Objective: The asterion is an important cranial anatomical landmark used in surgical approaches to the posterior cranial fossa, which is one of the most complex and surgically challenging regions of human anatomy due to the density of neurovascular structures. This study aims to examine the morphological and morphometric variations of the asterion to determine its preoperative localisation and help neurosurgeons reduce possible complications by providing an understanding of the detailed anatomy of the asterion in surgical approaches applied in posterior cranial fossa pathologies. Methods: In our study, adult human dry skull specimens (44 intact, 104 hemi skulls) with unknown demographic data were analysed. The asterions were first examined morphologically and categorised into two classifications. These classifications were based on the presence of wormian bone and the distance from the Frankfurt horizontal plane (FHP). Morphometric measurements were based on anatomical landmarks in the human skull. The landmarks used in the measurements were the lambda (L), FHP, the root of the zygomatic arch (RZA), the tip of the mastoid process (TMP), Henle’s spine (HS), external occipital protuberance (EOP), basion (B), opisthion (O) and porion (P). Results: The morphological classification of the asterions was examined. Type 1 and Type 2 were determined as 13.02% and 86.98%, respectively, according to the presence of the wormian bone. In the classification, according to the distance to the FHP, Type 1 was 9.90%, Type 2 was 58.85% and Type 3 was 31.25%. In morphometric measurements, the mean distance of the asterion to L was 85.16 ± 5.64 mm and 84.41 ± 5.43 mm on the right and left sides, respectively. The mean distance of the asterion to the FHP was 13.17 ± 6.81 mm and 14.01 ± 6.96 mm on the right and left sides, respectively. The mean distance of the asterion to the RZA was 56.18 ± 3.58 mm and 56.64 ± 3.69 mm on the right and left sides, respectively. The mean distance of the asterion to the TMP was 49.42 ± 4.16 mm and 48.91 ± 4.03 mm on the right and left sides, respectively. The mean distance of the asterion to HS was 46.15 ± 3.74 mm and 46.69 ± 3.79 mm on the right and left sides, respectively. The mean distance of the asterion to the EOP was 63.19 ± 4.13 mm and 62.71 ± 4.07 mm on the right and left sides, respectively. The mean distance of the asterion to B was 73.50 ± 3.73 mm and 72.96 ± 3.51 mm on the right and left sides, respectively. The mean distance of the asterion to O was 62.46 ± 2.88 mm and 62.23 ± 2.85 mm on the right and left sides, respectively. Finally, the mean distance of the asterion to P was 49.51 ± 3.87 mm and 50.32 ± 3.94 mm on the right and left sides, respectively. Conclusion: The results obtained in our study suggest that the accurate preoperative positioning of the asterion may contribute to reducing complications that may develop in neurosurgeons’ surgical approaches to the posterior cranial fossa.
