Do We Vary from Caucasians! Cephalometric Analysis for Orthognathic Surgery in Chhattisgarhi Population

Abstract

Aim: The aim of this study is to deduce the cephalometric norms for orthognathic surgery in Chhattisgarh population by comparing with the analysis given by Burstone et al. for hard tissue and Legan and Burstone for soft tissue. Materials and Methods: Lateral cephalograms of 70 subjects (35 male and 35 female) aged between 18 and 25 years having class I malocclusion, acceptable facial profile were recorded and traced for the analysis and interpretation using landmarks and values given by Burstone’s analysis were obtained and further comparison was done for the values obtained for the Chhattisgarh population with that of Caucasians. Results: Findings of our study were statistically significant as considerable skeletal differences were found between men and women of Chhattisgarh origin compared to Caucasian origin. Many contrasting findings were discovered in our study group from that of the Caucasian population with respect to the maxillo-mandibular relation, vertical hard tissues parameters. Less differences were found in horizontal hard tissue parameters and dental parameters among the two study populations. Conclusion: The differences found must be kept in consideration during analysis of cephalogram for orthognathic surgeries. Values obtained can be considered to assess deformities and surgical planning to achieve optimal results for Chhattisgarh population. Clinical Significance: The understanding of normal human adult’s facial measurements are important to assess craniofacial dimensions and facial deformities and to monitor postoperative results in orthognathic surgeries. Cephalometric norms can be a beneficial abet to clinicians in ascertaining the patient abnormalities. Norms define the ideal cephalometric measurements for patients based on factors such as age, sex, size and race. It has become apparent over years that significant variations do occur among and between the individuals of different racial origins.
