A clinical and cephalometric study of nasal morphology in post pubertal growth phase as a valid predictor of craniofacial growth direction and its relationship to facial skeletal morphology
Main Article Content
Abstract
Objectives: The present study is designed to predict the craniofacial growth by correlating nasal morphology, skeletal pattern and cervical vertebral maturation stages. This study emphasizes the importance of nasal dimensions in determining the growth so that newer and simpler diagnostic aids can be brought into use by further research for growing children.
Materials and Methods: Clinical examination of 120 subjects seeking orthodontic treatment (60 females and 60 males) who were in the post pubertal age group of 12-15 years and 13-17years, respectively, was performed. Pretreatment lateral cephalograms of these patients were obtained. Cephalometric evaluation was done for nasal and skeletal dimensions. The data was collected and correlated and analysed using SPSS software version 22.
Result: , CVM staging has shown significant correlation with nasal length (F value 4.89 and p value 0.001), nasal depth (F value 6.22 and p value 0.001), palatal length (F value 11.19 and p value 0.001), maxillary height (value 14.24 and p value 0.001), nasolabial angle (F value 2.84 and p value 0.027) and nasofrontal angle (F value 4.12 and p value 0.004). Age showed highly significant correlation ( F value 14.49 and p value 0.001) with CVM staging.
Conclusion: Clinical and lateral cephalometric assessment of nasal morphology is a reliable method of growth prediction which is of greatest importance in orthodontics.
