Soft tissue nasal profile changes

الملخص EN

Aims: To reveal the changes of the soft tissue profile of the nose, that include; length, height and depth of the nose among four age groups.

Materials and Methods: The studying sample subjects included 48, 41, 50 and 44 individuals of age 11, 12, 13 and 14 years respectively.

The subjects were Iraqi individuals of class I normal occlusion, who live in center of Mosul City.

All subjects were radiographed with the lateral cephalometric films, these films were traced and drawing the linear parameters of the nose, the tracing involve the length (N`–Prn), width (N–Sn) and depth (Prn– Prn`).

The results were subjected to the descriptive and variance analyses.

Results: The results appeared in males the length of the nose increase in dimension with no significant differences when compared among the four age groups, whereas in females showed significant increase when compared the 11, 12 years with 13 years and with 14 years age groups.

While, the h weight of the nose (N`–Sn) appeared in males and females significantly increase at 14 years age group when compared with other age groups.

But s ignificantly increased at 12 years age group as compared with 11 years age group, in males only.

Meanwhile, the depth of the nose (Prn–Prn`) displayed significantly increase at age 14 years group when compared with 11 and 12 years age groups for both sexes.

The comparison between sexes for the nose parameters demonstrated that the length, width and depth of the nose displayed significantly increase in males than females at 11 years age group and no significantly differences at other age groups.

Conclusions : The conclusions of the study are that the nose have significantly increase between 11 and 14 years age group in both sexes, the nasal profile parameters have insignificant difference in dimensions among 12, 13 and 14 years age groups.
