Öğe An evaluation on the morphology of the nasal bone, piriform aperture, and choana on dry skulls(Wolters Kluwer Medknow Publications, 2020) Kabakci, Anil Didem; Saygin, Duygu Akin; Alpa, Serife; Buyukmumcu, Mustafa; Yilmaz, Mehmet TugrulIntroduction: Piriform aperture (PA) and nasal bone (NBs) are important structures that contribute to the formation of the nose. Both anatomic structures show differences based on ethnicity, gender, and age. Hence, it is widely used to determine sex in science branches such as anthropology and forensic medicine. Furthermore, morphometry of the PA and choana is an important criterion for physiological nasal respiration of individuals. Recognition of structural differences of PA, NB, and choana along with all this information becomes important during maxillofacial procedures to be performed especially in plastic and reconstructive surgery. The aim of the present study is to determine the individual differences in NBs, PA, and choana. Material and Methods: This study was conducted on 83 Turkish dried skulls and PA, NBs, and choana was examined as morphometrically. PA was classified into seven types and NB was classified into eight subtypes. Results: The most common type of PA was found type 5 (20%-24.1%) and the least most common type of PA was type 7 (4%-4.8%). Type 1 was determined as the most common observed shape of the NB. The mean width of the choana on the right and left sides was found 13.21 +/- 1.4 and 13.98 +/- 1.81 mm, respectively. Moreover, the mean height of the choana on the right and left sides was found 25.56 +/- 3.06 and 26.1 +/- 2.5 mm, respectively. Discussion and Conclusion: We believe that obtained data from our study will constitute a morphometric data set and will be useful in a wide range of fields from forensic science to reconstructive surgery.Öğe Morphometric Analysis of Suprarenal Glands (Adrenal Glands) with Multislice Computerized Tomography(Soc Chilena Anatomia, 2017) Akin, Duygu; Yilmaz, Mehmet Tugrul; Ozbek, Orhan; Ozbiner, Huseyin; Cicekcibasi, Aynur Emine; Buyukmumcu, Mustafa; Kabakci, Anil DidemThe aim of our study are to determine the shape, vertebrae level, height, volume, corpus medial and lateral branch thicknesses of AG and the distance from some neighboring structures on multidetector computed tomography (MDCT) images and also to determine the relationship between these data and gender, age, height, weight and body mass index (BMI). The study was conducted on a total of 420 MDCT images consisted of 220 male (mean age 63.44 +/- 8.00, 50-81 years), 200 female (mean age 61.23 +/- 7.95, 50-84 years) healthy individuals. Vertebrae level of AG (VLAG), height of AG (HAG), adrenal gland volume (VAG), corpus thickness of AG (CTAG), medial section thickness of AG (MTAG) and lateral section thickness of AG (LTAG) were investigated. In our study, RAG were observed on T12 vertebrae level in 38.19 % of males and 42.5 % of females and LAG were also observed at that level in 39.55 % of the male and 51 % of the female individuals. RAG were observed in all males and 98.5 % of the females and LAG were observed 88.63 % of the males and 94 % of the females Y shaped. VAG were observed lower in males compared to females in age groups and VAG was observed increasing with age in males; decreased in 60-69 age group of females and increased again in 70 and plus age group. The aim of this study is to determine normal ranges of AG sizes and the relationship of each one with sex, age, height, weight and BMI.
