Evaluation of Skeletal Cephalometric Values for Orthognathic Surgery in Adult Patients Visiting Chitwan Medical College

Abstract

Introduction: Successful orthognathic surgery relies on the accurate diagnosis of facial, skeletal, and dental issues. The purpose of this study is to evaluate and compare Skeletal cephalometric values for orthognathic surgery in Nepalese adults and to compare with Caucasians.

Materials and Methods: One hundred adult patients (33 males and 67 females), with an age range of 18-36 years, were selected for the study. The subjects included had skeletal Class I, Average Growth Pattern, no craniofacial abnormality, and no previous history of orthodontic treatment. The Skeletal cephalometric norms for orthognathic surgery analysis values for the Nepalese population were established and compared with those of Caucasians.

Results: All the cephalometric parameters, except for facial convexity angle in females, maxillary protrusion in females, mandibular prognathism, chin protrusion, mandibular plane angle, and gonial angle, were less in the Nepalese population than in Caucasians.

Conclusion: The cephalometric parameters in the Nepalese adults are significantly different from those of the Caucasian population. These racial differences, which are evident in this study, should be kept in mind while charting out a plan for orthognathic surgery for the Nepalese adults.
