Haller hücrelerinin tespitinde KIBT ve panoramik görüntülemenin karşılaştırmalı analizi

Amaç: Bu çalışmanın amacı, KIBT ile daha önce tanımlanan Haller hücrelerinin belirlenmesinde panoramik radyografinin etkinliğini değerlendirmektir. Ek olarak, Haller hücrelerinin varlığı ile maksiller sinüsün mukozal kalınlaşması arasındaki ilişkiyi de değerlendirmeyi amaçladık.Gereç ve Yöntemler: KIBT taramalarında tespit edilen Haller hücreli 162 hastanın panoramik radyografilerinde 324 paranazal sinüs analiz edildi. KIBT görüntülerinde maksiller sinüslerin mukozal kalınlaşma varlığı değerlendirildi. Toplanan verilerin istatistiksel analizinde Ki-kare testi, Kappa analizi, t testi kullanıldı.Bulgular: KIBT ile hastaların panoramik radyografisi arasında istatistiksel olarak anlamlı bir fark bulundu. Haller hücrelerinin varlığı ile maksiller sinüste görülen mukozal kalınlaşma arasında bir ilişki bulunamadı.Sonuç: Haller hücrelerinin KIBT taramalarında görünürlüğü panoramik radyograflarla korele görünmemektedir. Haller hücrelerinin varlığı ile maksiller sinüste görülen mukozal kalınlaşma arasında ilişki yoktu.ANAHTAR KELİMELER Haller hücresi, konik ışınlı bilgisayarlı tomografi, mukozal kalınlaşma, panoramik radyograf

Comparison of Panoramic, Lateral Skull Projection and CBCT Images in Detection of Mandibular Condyle Fractures

Objectives: Condyle fractures constitute 17.5–52% of all mandibular fractures. Our first aim was to investigate whether panoramic radiography or LSP images with lower radiation dose can be used instead of CBCT in the diagnosis of vertical condylar fractures. The second aim of the study was to compare observers' capabilities in diagnosing these fractures. Materials and Methods: A sample consisting of 15 fresh cadaver mandibles with 30 condyles frozen within 24 hours post-mortem was randomly selected. Vertical fractures from the lateral 2/3 of the condyle head with 0.5 (10 condyles) and 1mm (10 condyles) thickness were created using a fret saw. After creating condyle fractures, digital panoramic, LSP, and CBCT images were acquired. Two dentomaxillofacial radiologists with 15 years of experience, two dentomaxillofacial radiologists with five and seven years of experience, and two newly graduated dentists have evaluated the images. The success of the observers in diagnosing the vertical condyle fracture in each imaging method, intra-observer and inter-observer agreement was evaluated. Results: The success of all dentists in determining the condyle fractures using LSP images was higher than the success they achieved using panoramic images, but it was not sufficient. Using different imaging options with CBCT, all diagnoses made by new graduates and dentomaxillofacial radiologists with five and 15 years’ experience were 100% compatible with the gold standard (AC1: 1 (1–1)). Conclusions: For the diagnosis of vertical condyle fractures, conventional techniques (panoramic and lateral jaw imaging methods) were found to be insufficient

Hemangioma Presenting With Multiple Phleboliths: Case Report with CBCT Findings

Hemangiomas are benign tumors of infancy that display a rapid growth phase with endothelial cell proliferation. Phleboliths are calcified thrombi found in veins, venulae and sinusoidal vessels of hemangiomas. In the head and neck, phleboliths nearly always signal the presence of a hemangioma. Hemangioma with multiple phleboliths is described including its features on panoramic radiography and cone beam computed tomography images.
