ÖZET
 Amaç: Damağın ön kısmında alveolar kemik seviyesinde izlenebilen canalis sinuosus (CS) olarak bilinen kanalların çapının, lokalizasyonunun ve sıklığının cinsiyet ve yaşa göre dağılımlarının belirlenmesidir. Ek olarak, konik ışınlı bilgisayarlı tomografi (KIBT)'lerde aksiyel, koronal ve sagital kesitlerde izlenen CS'lerin ortopantomografi (OPG) bulgularının incelenmesi ve karşılaştırılmasıdır. Gereç ve Yöntemler: Toplam 480 (240 erkek, 240 kadın) bireyin KIBT görüntüleri kullanılarak retrospektif incelemesi yapıldı. CS'lerin anatomik özellikleri KIBT görüntülerinde multiplanar reformasyon kullanılarak değerlendirildi. Parametreler yaş, cinsiyet, kanal lokalizasyonu, komşu dişlerle pozisyon ilişkileri ile kanalın tek veya çift taraflı varlığı olarak belirlendi. Aksiyal görüntülerde 1 mm ve 1 mm'den büyük çaplı kanallar belirlendi ve kaydedildi. KIBT'de saptanan 31 adet CS, OPG görüntülerinde incelenip kanalın görünürlüğü ve özellikleri değerlendirildi. Bulgular: Kadınlar ve erkekler arasında prevalans açısından belirgin fark izlenmedi. Yaş ortalaması 46,07 (SS 12,52) yıl bulundu. Yirmi bir bireyde maksiller alveolar kemiğe açılan toplam 31 CS saptandı. CS'lerin çap ortalaması aksiyal kesitlerde 1,37 mm (min 1 mm; max 2 mm) bulundu. Otuz bir kanaldan 26'sında CS ile uyumlu OPG bulgusu izlenmezken, beşinde radyoopak çizgisel hat arasında radyolusent görünümde kanal belirlendi. Sonuç: Bu çalışmanın sonuçlarına göre, CS'nin alveolar kemiğe açılan varyasyonlarının oranı yalnızca %4,37 bulunmuştur. Bu da CS'lerin büyük oranının maksiller anterior bölgedeki alveolar cerrahi komplikasyonları için risk oluşturmadığını düşündürmektedir.

ABSTRACT
 Objective: Aim of this study is to determine the frequency, localization, and diameter of the canalis sinuosus (CS) in the anterior palate region at the alveolar bone level. Additionally, it aims to analyse and compare the findings obtained from orthopantomography (OPG) of CS for which axial, coronal and sagittal cross-sections have been viewed using cone beam computed tomography (CBCT). Material and Methods: A retrospective analysis has been carried out using CBCT images of 480 (240 male, 240 female) individuals. The anatomical characteristics of the CS were evaluated using multiplanar reformation of CBCT views. Parameters were determined as age, sex, localization of the canal, its relative position to neighbouring teeth and whether it was unilateral or bilateral. The canals with a diameter ≥1 mm in axial images were determined and recorded. Thirty one canalis sinuosus, detected in CBCT, have been examined in OPG images to evaluate the visibility and characteristics of the canal. Results: No significant difference has been found between men and women in terms of prevalence. Mean age was 46.07 (SD 12.52). In total, 31 CS which has an opening into maxillary alveolar bone have been detected in 21 individuals. Mean diameter was found to be 1.37 mm (min 1 mm; max 2 mm) in axial sections. In 26 out of 31 canals no OPG finding relevant with CS is observed, yet in 5 of them, presence of radiolucent canals between radiopaque lines has been detected. Conclusion: According to the results of this study, the rate of having the variation of CS which opens to maxillary alveolar bone is found to be only 4.37%. This suggests that not great ratio of the CS poses a risk for complications during alveolar surgery at maxillary anterior region.
