Aim: The aim of this study was to evaluate sella turcica bridging, ponticulus posticulus calcification and sella turcica volume in individuals with different skeletal malocclusions on cone beam computed tomography (CBCT) images.
Material and Methods: Sella turcica volume calculations were performed on a total of 84 individuals, 28 individuals in each class. Ponticulus posticus calcification and sella turcica bridging were performed on a total of 162 patients (27 male, 27 female) in each class. Sella turcica bridging and ponticulus posticulus calcifications were analyzed on sagittal sections of CBCT images and data were recorded as no bridging, partial bridging and complete bridging. Sella turcica volume calculations were performed with 3D-DOCTOR (Able Software Corp., Lexington, MA, USA) by manual segmentation method on KIBT sagittal sections.
Results: There was no statistically significant difference in ponticulus posticus calcification and sella turcica bridging according to skeletal malocclusions and gender. Sella tursica volume did not show a statistically significant difference between skeletal malocclusions, while sella tursica volume was found to be statistically significantly higher in female than in male individuals. (p=0.004, p<0.005).
Conclusion: Ponticulus posticus calcification, sella turcica bridging and sella turcica volume do not vary according to skeletal malocclusions. Sella turcica volume is statistically significantly higher in female individuals. It should be kept in mind that calcifications and shape changes in structures such as the sella turcica and atlas bone on lateral cephalometric radiographs may be a sign of certain diseases.

Farklı Maloklüzyonlara Sahip Bireylerde Sella Tursika Köprüleşmesi, Pontikulus Postikus Kalsifikasyonu ve Sella Tursika Hacminin Karşılaştırılması

Öz

Amaç: Bu araştırmada farklı iskeletsel maloklüzyona sahip bireylerde sella tursika köprüleşmesi, pontikulus postikus kalsifikasyonu ve sella tursika hacminin konik ışınlı bilgisayarlı tomografi (KIBT) görüntülerinde değerlendirilmesi amaçlanmıştır.
Gereç ve Yöntemler: Sella tursika hacim hesaplamaları her bir sınıfta 28 birey; toplam 84 birey üzerinde yapılmıştır. Pontikulus postikus kalsifikasyonu ve sella tursika köprüleşmeleri her bir sınıfta 54 (27 kadın, 27 erkek) toplam 162 hasta üzerinde yapılmıştır. Sella tursika köprüleşmeleri ve pontikulus postikus kalsiifikasyonları KIBT görüntüleri sagittal kesitler üzerinde analiz edilerek; köprüleşme yok, kısmi köprüleşme ve tam köprüleşme şeklinde veriler kaydedilmiştir. Sella tursika hacim hesaplamaları KIBT sagittal kesitleri üzerinden manuel segmentasyon yöntemi ile 3D-DOCTOR (Able Software Corp., Lexington, MA, USA uygulaması ile yapılmıştır.
Bulgular: Pontikulus postikus kalsifikasyonu ve sella tursika köprüleşmesi açısından iskeletsel malokluzyonlara ve cinsiyete göre istatistiksel olarak anlamlı bir fark gözlenmemiştir. Sella tursika hacmi iskeletsel malokluzyonlar arasında istatistiksel olarak anlamlı bir fark göstermezken kadınlarda sella tursika hacmi istatistiksel olarak anlamlı bir şekilde erkeklere göre daha yüksek olduğu tespit edilmiştir (p=0.004, p<0.005).
Sonuç: Pontikulus postikus kalsifikasyonu, sella tursika köprüleşmeleri ve sella tursika hacmi iskeletsel malokluzyonlara göre değişiklik göstermemektedir. Sella tursika hacmi kadınlarda istatistiksel olarak anlamlı bir şekilde daha yüksektir. Lateral sefalometrik radyografilerde sella tursika ve atlas kemiği gibi yapılarda meydana gelen kalsifikasyonların ve şekil değişikliklerin bazı hastalıkların da habercisi olabileceği unutulmamalıdır.
