Abstract
Objectives : This study aims
to investigate incidence of
nostril asymmetry and deviation of nasal bony pyramid and caudal septum
and to examine their association with dominant hand in male adolescents.
Methods: Totally 546 male healthy adolescents aged 15 to 17
years were included. Each participant was examined for presence or
absence of nasal bone pyramidal deviation, caudal septal deviation, side
of deviation, and nostril asymmetry. The dominant hand was recorded.
Results: Of participants, 85 were aged 15 years, 291 were aged
16 years, and 168 were aged 17 years. Mean age was 16.148±0.667 years.
Of all participants, 91% (n=497) were right-handed and 9% (n=49) were
left-handed. Distribution of the dominant hand across age groups was
comparable (p=0.921). In case of deviation to the right, 61.2% (n=74)
were right-hand dominant, while 58.3% (n=7) of those with deviation to
the left were left-hand dominant. According to hand dominance and size
of nostrils, 92.1% (n=105) of those with a larger left nostril were
right-handed and 7.9% (n=9) were left-handed.
Conclusions: Male
adolescents had a significant deviation of caudal septum to the right
side with smaller right nostrils. However, hand dominance and side of
deviation were not significantly associated with nasal bony pyramid and
caudal septum.
