Amaç: Rinolitler nazal kavitede endojen ve eksojen nidusların kalsifikasyonları ile oluşan mineralize olmuş, sert, yoğun ve düzensiz odaklardır. Genellikle asemptomatik olan rinolitler nadir olarak görülmektedir. Bu çalışmada, Konik Işınlı Bilgisayarlı Tomografi (KIBT) görüntülerinde rinolitlerin görülme sıklığının, lokalizasyonlarının ve karakteristik özellikle-rinin değerlendirilmesi amaçlanmıştır. Gereç ve Yöntem: İstanbul Üniversitesi Diş Hekimliği Fakültesi Ağız, Diş ve Çene Rady-olojisi Anabilim Dalı’nda 01.01.2017 ile 01.07.2019 tarihleri arasında alınan KIBT görüntüleri değerlendirilmiştir. Nazal kaviteyi içermeyen ve hareket artefaktı bulunan görüntüler çalışma dışında tutulmuştur. 8380 KIBT görüntüsü taranmış olup uygun kriter-lerde bulunan 3124 görüntü çalışmaya dahil edilmiştir. Görüntüler 2 uzman 2 araştırma görevlisi tarafından değerlendirilmiştir. Bulgular: Çalışma kriterlerine uygun 3124 KIBT görüntüsü değerlendirilmiş olup 7 adet rinolit olgusu tespit edilmiştir. 5 rinolit olgusu sağ nazal kavitede, 2 rinolit olgusu sol nazal kavitede izlenmiştir. 5 rinolit olgusu inferior nazal konkada görülürken 1 olgu orta nazal konkada, 1 olgu da hem orta hem de inferior nazal konkada izlenmiştir. Olguların birinde nazal kavite tabanında perforasyon, bir diğerinde nazal septum deviasyonu tespit edilmiştir. Sonuç: Dental teşhis ve tedaviler sırasında alınan KIBT görüntülerinde rinolitler tesadüfen gözlenebilir. Bu olgular geç teşhis edildiğinde veya tedavi edilmediğinde septal veya antral perforasyon, nazal septum deviasyonu gibi semptomlara neden olabileceği bilinmektedir. Rinolitlerin lokalizasyonunun belirlenmesinde, karakteristiğinin tespitinde ve tedavi plan-lamasında KIBT önemli bir yer tutmaktadır.
Rhinoliths are mineralized, hard, dense and irregular foci formed by the calcification of endogenous and exogenous nidus in the nasal cavity. This condition is rarely seen and usually asymptomatic. In this study, it is aimed to evaluate the frequency, localization and characteristic features of rhinoliths in Cone-Beam Computed Tomography (CBCT) images. Materials and Method: The CBCT images taken between 01.01.2017 and 01.07.2019 at the Department of Oral and Maxillofacial Radiology of Istanbul University Faculty of Dentistry were evaluated. The images with motion artefact and images without a nasal cavity were excluded from the study. 8380 CBCT images were scanned and 3124 images that comply with the criteria were included in the study. Images were evaluated by 2 experts and 2 re-search assistants. Results: 3124 CBCT images matching the study criteria were evaluated and 7 rhinolith cas-es were identified. 5 cases of rhinolith were located on the right side of the nasal cavity whereas 2 others were on the left side of the nasal cavity. 5 rhinolith cases were observed at the inferior nasal concha, 1 case was seen at the middle nasal concha and the last one was seen both at the inferior and the middle nasal concha. One case included perforation of the nasal cavity base whereas the other had nasal septum deviation. Conclusion: Rhinoliths can be observed incidentally on CBCT images taken during dental diagnosis and treatment. In case of late diagnosis or when they are not treated properly, these cases are known to cause symptoms such as septal or antral perforation, nasal sep-tum deviation. CBCT is crucial for determining the localization, characterization and treatment planning of rhinoliths.
