Prevalence of fossa navicularis among cleft palate patients detected by cone beam computed tomography

Amaç: Fossa navicularis, radyografik olarak klivusun inferior tarafında bir kemik kavitesi şeklinde gözlenen anatomik bir varyasyondur. Daha önceki çalışmalarda fossa navicularisin görülme sıklığının ender olduğu ortaya konmuş olsa da damak yarığı olan hastalardaki görülme sıklığı ile ilgili daha önce yapılmış bir çalışma bulunmamaktadır. Bu çalışmada amaç, damak yarığı olan hastalarda fossa navicularis görülme sıklığının konik ışınlı bilgisayarlı tomografi (KIBT) ile incelenmesidir.Gereç ve Yöntem: Herhangi bir sendromu olmayan ve damak yarığı bulunan 45 hastaya ait KIBT görüntüleri bu çalışmaya dahil edilmiştir. KIBT görüntüleri üzerinde sagital düzlemde fossa navicularis varlığı belirlenmiştir. Ayrıca bu hastalara ait yaş ve cinsiyet bilgileri kaydedilmiştir. Bulgular: Çalışmaya dahil edilen 45 hastanın 20'si (%44,4) kadın, 25'i (%55,6) erkektir. Yaşları 10 -

Damak yarığı hastalarında fossa navicularis görülme sıklığının konik ışınlı bilgisayarlı tomografi ile değerlendirilmesi

Aim: Fossa navicularis is an anatomic variation, radiographically demonstrating as a bony, notch-like dehiscence on the inferior aspect of the clivus. Even though, the prevalence of fossa navicularis was reported to be rare, there are no previous studies reporting the prevalence of fossa navicularis among cleft palate patients. The objective of this study is to determine the prevalence of fossa navicularis among cleft palate patients using cone beam computed tomography (CBCT).Materials and Methods: The study group consisted of nonsyndromic 45 cleft patients having a CBCT scan. On CBCT images, the presence of fossa navicularis was detected on sagittal plane. Age and gender of the patients were also recorded.Results: Among 45 patients, 20 (44.4%) were female, whereas 25 (55.6%) were male. Mean age of the patients, with an age range of 10 - <40, was found as 18.5±7.6. Fossa navicularis was identified in 13 cleft patients (28.8%). Among these patients, 4 were female (8.9%), whereas 9 were male (20%), and their age ranged between 10 and 33 (mean age: 22.4±8.2).Conclusion: The prevalence of fossa navicularis in cleft palate patients was found to be higher than previously reported in noncleft patients
