Abstract
ABSTRACT
Background
Knowledge of the normal appearance of lip-nose complexes in a particular ethnicity
or race helps to plan and modify surgical techniques for their deformity.
Objective
To determine the shape of the philtral column and nostril in children of two ethnic
groups (Aryans and Mongoloids) of the Nepalese population and compare them to
see if any variation exists.
Method
The present prospective study was carried out between December 2021 to January
2023 among 200 children of age 5-12 years. The children meeting our inclusion
criteria were divided equally into Aryan and mongoloid groups based on the caste
system in Nepal. Facial photographs were obtained in frontal and basal views. They
were analyzed to determine the shape of the philtral column and nostril shape based
on Mori’s classification system.
Result
Out of 200 children, 123 were males and 77 were females. The most common type
of philtral and nostril shape in the Nepalese population was triangular and teardrop
respectively. Triangular and concave type philtral shape was predominant in Aryans
whereas triangular and parallel type was predominant in Mongoloids however the
variation was not significant. Similarly, teardrop nostrils were most common in both
ethnic groups.
Conclusion
The results provide a morphological pattern and variation in the philtral and nostril
shape in the two major ethnic group of Nepalese population.
