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 were higher 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.
