Abstract

Background: The morphology of the nasal and craniofacial structures is a significant characteristic of the facial appearance of an individual. The soft tissue facial form depends on the hard tissue skeletal structures. The nasolabial angle depicts a close relationship between the lips and the nose, affecting the facial profile. There is however less data in orthodontic literature regarding the relationship between the nasal morphology and the sagittal and vertical maxillary growth pattern. Aim and Objectives: 1. To evaluate the relationship between nasal morphology and skeletal maxillary growth pattern. 2. To evaluate the relationship between the degree of upturn of the nose and the inclination of the palatal plane. Materials and Method: An analysis of 70 lateral cephalograms of adults between the ages of 17 and 25 years with no previous history of trauma, surgical intervention, or congenital disorders was conducted. A total of 16 parameters, including 10 craniofacial and 6 nasal parameters were measured on each lateral cephalogram. The Pearson correlation analysis was used to determine the correlation between the above parameters. Results: Highly positive correlations were present between the nasal length and inclination of the palatal plane, upper anterior facial height and maxillary length. Nasal length has a highly positive correlation with nasal depth however a negative correlation was observed with the nasal upward tip angle and nasal tip angle. Conclusion: The clinical significance of this study is that the facial form, facial prominence and nasal length are associated with the height and length of the maxilla. Nasal length was seen to be significantly positively correlated to maxillary length, upper anterior facial height and inclination of the palatal plane.
