Steiner cephalometric analysis in orthognathic surgery patients treated at Department of Oral and Maxillofacial Surgery, Hasan Sadikin General Hospital, Bandung

Abstract

Objective: Orthognathic surgery is surgery on abnormalities of dentofacial that occur in the maxilla, mandible, or both. Determine measurement of the type of dentoskeletal abnormality in malocclusion using cephalometric analysis. Steiner analysis is used because it is considered that the Sela tursica-nasion-point A (SNA) angle, Sela tursica-nasion-point B (SNB) used to describe the relationship between the maxilla and the mandible. Material and Methods: The study involved 30 patients who underwent orthognathic surgery between April 2017 and April 2022 at Hasan Sadikin Hospital Bandung. Cephalometric radiography was utilized for assessment, employing the Steiner method to analyze various angles. Patient characteristics, including gender and age, were also observed. Parameters such as the average angle of SNA, SNB, and ANB were examined, alongside diagnoses, the number of corrected jaws, and the type of orthognathic surgery. Results: The findings indicated a predominance of male orthognathic surgery patients (63.3%), with the majority falling within the age range of 19 to 20 years (40%). Grade III malocclusion was the most prevalent diagnosis (96.7%), with double jaw correction being the most common procedure performed (90%). Bilateral sagittal split osteotomy was utilized in 93% of cases, followed by Le Fort I osteotomy in 96.7% of cases and chinplasty in 16.7% of patients. The average SNA, SNB and ANB was 83.8o, 90.6o, and -6.8o, respectively. Conclusion: The findings indicated a higher frequency of orthognathic surgery among patients diagnosed with class III malocclusion. Additionally, a notable proportion of patients underwent simultaneous orthognathic surgery on both the maxilla and mandible.
