Objective: The orbit is an important cavity containing vision-related formations and important neurovascular structures, and adjacent to various regions. This study aimed to evaluation, by multidedector computed tomography (MDCT) images, the morphometry of orbit by examining its changes according to gender and body side, and developments according to age, in Turkish population. Materials and Methods: A total of 200 individuals’s (94 females,106 males;400 sides) MDCT images were evaluated. Images were examined according to the gender, body side, and the anatomical structures development. Results: The height, width and depth of the orbit were determined as 36.04±2.97 mm, 32.33±2.59 mm, 38.35±3.32 mm on the right side, 35.79±3.18 mm, 32.29±2.67 mm, 38.13±3.21 mm on the left side, respectively, in healthy subjects. The height and width of the orbit were found to be statistically significantly larger on both sides in men than in women (p˂0.05). Conclusion: Comprehensive information about the orbit and associated apertures is quite important for clinicians working in this area, damage to these structures can cause serious complications. In addition, determining the morphometry of the orbit can be used as an important parameter for determining gender, age and race in forensic medicine., Amaç: Orbita bağlantı sağladıkları boşluklar, komşu olduğu bölgeler ve içerdiği yapılar sebebiyle oldukça önemli bir bölgedir. Çalışmamızda Türk popülasyonunun orbita morfometrisini, çok kesitli bilgisayarlı tomografi (ÇKBT) görüntülerinde cinsiyete, vücut tarafına göre farklılıklarını, yaşa bağlı gelişimini değerlendirmeyi amaçladık. Gereç ve Yöntem: 94’ü erkek, 106’sı kadın olmak üzere toplam 200 bireyin (400 taraf) ÇKBT görüntüleri üzerinde ölçümler yapıldı. Görüntüler cinsiyet, vücut tarafı ve anatomik yapıların gelişimlerine göre değerlendirildi. Bulgular: Sağlıklı bireylerde orbita yüksekliği, genişliği ve derinliği sırasıyla sağ tarafta ortalama 36,04±2,97 mm, 32,33±2,59 mm, 38,35±3,32 mm iken sol tarafta 35,79±3,18 mm, 32,29±2,67 mm, 38,13±3,21 mm olarak belirlendi. Orbita’nın yüksekliği ve genişliği her iki tarafta da erkeklerde kadınlardan istatistiksel olarak anlamlı derecede büyük olduğu tespit edildi (p˂0,05). Sonuç: Orbita ve ilişkili açıklıklar hakkında kapsamlı bilgi, ilgili bölgede çalışan klinisyenler açısından oldukça önemlidir, bu yapıların zarar görmesi ciddi komplikasyonlara neden olabilir. Bununla birlikte, orbita’nın morfometrisi adli tıpta cinsiyet, yaş ve ırk tespiti için önemli bir parametre olarak kullanılabilir.

WOS: 000487459600032, PubMed: 31302743, Purpose We aimed to determine the position and size of the sphenoid sinus (SS) in our study and compare the results of the measurements relative to age, gender, and the presence of pituitary adenoma using multidetector computerized tomography (MDCT). Methods We retrospectively evaluated the paranasal sinus computerized tomography (CT) images of 200 individuals (age range of all the individuals 4-84 years; 101 females, 99 males; age range of individuals with pituitary adenoma 15-63 years; 15 females, 9 males) with 24 pituitary adenomas. The shape of SS were identified and classified, volume were measured by MDCT also for individuals with pituitary adenoma. Results It was determined that the volume averages were significantly affected by the type of SS. Among all the individuals studied, the sellar type of SS was most frequently observed (41.5%), followed by the postsellar type (38.5%), and the least observed was the presellar type (9%). The volume of the SS is bigger in males than females although the volume is not affected by the presence of pituitary adenomas. The development of the SS continues until the age of nine. Conclusion The morphology and morphometry of the SS show individual differences. These anatomic variations are important for decision making and application for surgical interventions (especially transsphenoidal surgery).
