Objective: The aim of this study was to evaluate morphometric measurements of the upper end, middle area and lower end of the nasolacrimal canal (NC), the length of NC, the angle between NC and the Frankfurt horizontal plane, using cone beam computed tomography. Material and Methods: Retrospective database screening of forty-nine patients were evaluated and morphometric measurements were performed. Results: The mean age of the study population (49 patients) was 35.46 years (min 16, max 81). The angle between the NC and the horizontal plane of Frankfurt was greater on the right side. As the transverse dimensions of the upper end of the NC increased, the angle between the NC and the Frankfurt horizontal plane increased, and as the transverse and sagittal dimensions of the lower end of the NC increased, the angle between the NC and the Frankfurt horizontal plane increased. Conclusion: In light of the current information about NC anatomy, it was aimed that surgeons working in the face area can predict obstruction areas and plan frequently performed surgeries, such as dacryocystorhinostomy.

Amaç: Bu çalışmanın amacı, Nazolakrimal kanalın (NK) üst ucunun, orta kısmının ve alt ucunun boyutlarını, NK'nin uzunluğunu, NK ve Frankfurt yatay düzlemi arasındaki açıyı içeren morfometrik ölçümleri, konik-ışınlı bilgisayarlı tomografi kullanarak değerlendirmektir. Gereç ve Yöntemler: Veritabanında yapılan retrospektif taramada, kırk dokuz hastanın görüntüleri değerlendirilmiş ve belirtilen morfometrik ölçümler yapılmıştır. Bulgular: Çalışmada değerlendirilen yaş ortalaması 35.46 yıl olan (min 16, maks 81) 49 hastanın NK'nin boyutlarının üst uçtan alt uca doğru arttığı gözlendi. NK ve Frankfurt yatay düzlemi arasındaki açı sağ tarafta daha yüksekti. NK'nin üst ucunun enine boyutları arttıkça, NK ve Frankfurt yatay düzlemi arasındaki açı da artmış ve NK'nin alt ucunun enine ve sagittal boyutları arttıkça, NK ve Frankfurt yatay düzlemi arasındaki açı da artmıştır. Sonuç: NK anatomisi hakkında sunulan bu güncel bilgiler ışığında, yüz bölgesinde çalışan cerrahların, obstrüksiyon alanlarını öngörebilmeleri ve dakriyosistorinostomi gibi sıkça gerçekleşen ameliyatları rahat bir şekilde planlayabilmeleri hedeflenmiştir.
