Nasal septal deviation in a longitudinal growth sample

Objective: This retrospective longitudinal study attempts to determine the ontogenetic patterning of nasal septal deviation and if there is a relationship between a deviated septum and facial form growth and development. Methods: Nineteen females and twenty males were selected from the Iowa Facial Growth Study. Eighteen lateral cepalometric variables were analyzed and septal deviation was quantified using a percentage of deviation. A generalized Procrustes analysis was used to scale landmarks and generate principal components. Pearson correlation coefficients were used to analyze differences in shape. A Mann Whitney U-Test was used to analyze changes in septal deviation. Results: The first three principal components explained 56.23% of the variance. Only PC1 was significantly correlated with centroid size (r=0.82, P<0.0001). Mean percentage of septal deviation (0.620% ± 0.463%) was present at the youngest age group (3-4.9 years) and increased in each age group until adulthood, defined as over the age of 20 (0.991% ± 0.519). None of the first three principal components were found to be correlated to percentage of septal deviation. Conclusions: Nasal septal deviation has been found to increase in a longitudinal sample of subjects of northern European descent. Nasal septal deviation represents a disjunction in the growth of the nasal septum with the rest of the face. The amount and timing of nasal septal deviation that can cause nasal obstructions leading to vertical growth changes was not analyzed in this study and will require future study.
