Konik Işınlı Bilgisayarlı Tomografide Yumuşak Damak Morfolojik Tiplerinin Need’s Oranı Kullanılarak Değerlendirilmesi

Amaç: Bu çalışmanın amacı, Konik Işınlı Bilgisayarlı Tomografi (KIBT) kullanarak çeşitli yaş ve cinsiyet gruplarında yumuşak damak morfolojisini belirlemek ve Need’s Oranı, Velum Uzunluğu, Velum Genişliği ve Faringeal Derinlik ile ilişkisini bulmaktır. Gereç ve Yöntemler: 122 KIBT taraması velar morfoloji açısından analiz edildi ve farklı tiplere göre sınıflandırıldı. KIBT'de Velum Uzunluğu, Velum Genişliği ve Faringeal Derinlik ölçüldü. Need’s oranı, faringeal derinliğin velum uzunluğuna bölünmesiyle hesaplandı. Bulgular: Çalışmadaki tüm yumuşak damak tipleri arasında en yaygın olarak sıçan kuyruğu şekli bulundu. Erkeklerde ortalama yumuşak damak uzunluğu ve genişliği daha fazla iken, Need’s oranı kadınlarda daha yüksekti. Ortalama damak uzunluğu ile çeşitli yaş grupları arasında anlamlı bir ilişki vardı ve değerler yaş arttıkça arttı. Yaş grupları arasında ortalama damak genişliği ve İhtiyaç oranı arasında anlamlı bir fark yoktu. Sonuç: KIBT taramasında yumuşak damağın morfometrik analizi, damak morfolojisi tiplerindeki çeşitliliği anlamamıza yardımcı oldu. Anahtar Kelimeler: Faringeal derinlik, KIBT, Need’s oranı, Velum uzunluğu, Velum genişliği.

Evaluation of Soft Palate Morphological Types in Cone Beam Computed Tomography Using Need's Ratio

Objectives: The aim of this study is to determine the soft palate morphology in several age and gender groups and to find its relationship with Need's ratio, Velum Length, Velum Width and Pharyngeal Depth with using Cone Beam Computed Tomography (CBCT). Materials and Methods:122 CBCT scans were analyzed for velar morphology and classified into different types. Velum Length, Velum Width and Pharyngeal Depth were measured on CBCT. Need's ratio was calculated by dividing Pharyngeal Depth to Velum Length. Results: Of all the types of soft palates in the study, rat tail shaped was most commonly found. While the mean soft palate length and width was more in males, the Need's ratio was higher in females. There was a significant relationship between the mean velar length and various age groups and the values increased with increasing age. There was no significant difference between the mean velar width and Need's ratio between age groups. Conclusion: Morphometric analysis of the soft palate in the CBCT scan helped us understand the diversity in types of palate morphology.This study may be a source for research on the etiological causes of velopharyngeal insufficiency and Obstructive sleep apnea syndrome.
