Nose and skeletal patterns, is there a relationship?

الملخص EN

Background : This study aimed to evaluate the relationship between the nasal length and projection with the sagittal and vertical jaw parameters.

Material and method : One hundred digital true lateral cephalometric radiographs were selected from the files of the patients attending the orthodontic clinic in the College of Dentistry at Baghdad University and classified according to the ANB angle into class I and class II (50 cases for each group).

Eleven skeletal and 2 nasal soft tissue parameters were measured using AutoCAD program.

Independent samples t-test was used to evaluate the genders and classes differences and Pearson coefficient of correlation was used to show the relationship between the nasal and skeletal parameters.

Results : The results indicated that the males had longer and prominent noses in both classes.

On the other hand, there was non-significant correlation between the sagittal relation and the nasal parameters, while there was significant correlation between the facial heights and nasal parameters.

Conclusion : The noses in males were longer and more prominent than females.

The sagittal relation parameters had no influence on the nasal parameters in contrary to the facial heights.
