Steiner Analysis of Cephalometric in Orthognathic Surgery Patients of Department Oral and Maxillofacial Surgery Hasan Sadikin General Hospital Bandung of Period April 2017 – April 2022

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. Attention was carried out using cephalometric radiography and analyzed using the stainer method by observing angles also observing patient characteristics such as gender and age, average angle of SNA, SNB, ANB, diagnosis, number of corrected jaws and type of orthognathic surgery. Results: The results of this study showed that orthognathic surgery patients were more male (63.3%), most aged between 19 - 20 years (40%), diagnosis of grade III malocclusion (96.7%), double jaw correction action (90%), bilateral sagittal split osteotomy (93%), osteotomy le fort I (96.7%), chinplasty (16.7%), mean angle SNA (83.8), angle SNB (90.6), angle ANB (-6.8). Conclusion: The results showed that more patients underwent orthognathic surgery with class III malocclusion and underwent orthognathic surgery on the maxilla and mandible simultaneously Keywords: Orthognathic surgery, cephalometry, Steiner analysis, malocclusion
