    External ear anatomy and variations in neonates
    (Wiley, 2022) Erdem, Saadet; Fazlıoğulları, Zeliha; Ural, Ahmet; Karabulut, Ahmet Kağan; Doğan, Nadire Ünver
    It is aesthetically important that the auricle has a natural and beautiful shape. The sizes, position and symmetry of normal auricle are used for different purposes in different disciplines. A deformation in the auricle of neonates and its size or location on the face may indicate a possible anomaly. The aim of this study is to investigate the normal sizes, anomaly types, anomaly rates and the relationship between hearing screening test results and auricular anomaly of the neonatal auricle. The length, width, angle, and distance measurements of the auricle were made in neonates (n = 550). Anomaly types of auricle were observed. Goniometer was used to measure angles; digital caliper and ruler were used to measure lengths. Anomalies were detected by the method of observation. In the morphometric data of the neonatal auricle, differences were determined in length and width values in terms of gender. Various types of anomalies were observed in the right ear of 96 participants and in the left ear of 103 participants. Normal auricle size, position and symmetry are important for surgical reconstructions, hearing aid design, producing data banks on gender, age and ethnicity, and providing reference information for multiple diagnostic and forensic procedures. Recognition and early detection of auricular anomalies play an essential role in clinical diagnosis and their correction with special devices.

    Volumetric Analysis of Carpal Bones by Sex with 3D Slicer Software Program
    (Soc Chilena Anatomia, 2024) Celik, Nihal Gurlek; Erdem, Saadet; Kocak, Mehmet
    In this study, we aim to share the volumes of the carpal bone and the ratio of these volumes to the total volume of wrist bones from Computed Tomography (CT) images obtained from individuals of different ages and sex using 3D Slicer. Right wrist CT images of 0.625 mm slice thickness of 42 healthy individuals (21 female, 21 male) of both sexes were included in our study. Volume calculations were made by loading the images into 3D Slicer, an open-source software package. In this study, mean capitate volume was the largest in both sexes (male 3479.9 +/- 679.2; female 2207.1 +/- 272.1 mm(3)), while pisiform had the smallest mean volume (male 810.0 +/- 141.2; female 566.6 +/- 97.7 mm(3)). This order was ordered from largest to smallest as hamate, scaphoid, trapezium, lunate, triquetrum, trapezoid, and pisiform. According to this study, carpal bone volumes were larger in males than in females (p<0.001). The ratio of each carpal bone volume to the total carpal bone volume was calculated according to sex and it was found that there was no difference (p>0.05). In this study, it was seen that carpal bone volume differed according to sex. However, it was observed that the bone volumes of both sexes took up the same amount in the total bone volume. This information will be very useful in sex determination, 3D anatomical material creation, implant applications and reconstructive surgery.
