# Evaluation of Deviations Produced by Soft Tissue Fitting in Virtually Planned Orthopathic Surgery
## 3 Results
The data were grouped according to patients for whom the VSP was strictly followed and patients whose VSP was modified intraoperatively. Clear deviation was found in antero-posterior repositioning of Pg and SI for Class II patients, reaching an average deviation of almost 5 mm for Pg and 2.5 mm for SI. However, statistical significance was not achieved due to the small number of patients in the VSP-treated group: \(p\)-value = 0.915 for Pg and \(p\)-value = 0.8477 for SI. Only one patient in the Class II group followed the VSP, which led to a lack of statistical power. Therefore, almost all Class II procedures (five out of six--83%) requiring surgeon intervention due to the VSP sought a higher advancement than the one finally considered by the surgeon. More limited deviations were observed in Class III patients, where only two out of five (40%) deviated from the VSP. Furthermore, even in patients for whom the VSP protocol was not fully adhered to, minor deviations were exhibited. Table 3 shows the overall and subdomain results of the OQOL questionnaire grouped by dentofacial deformity class. Most patients had positive outcomes through all test subdomains, indicating satisfaction with orthognathic surgery. However, one patient was an outlier, showing an overall score of 58, which is associated with low satisfaction and issues related to the results of the surgery. However, we were aware that this patient had difficulty understanding the questionnaire, since the results do not match the patient's subjective evaluation of satisfaction. Therefore, we suggest not considering this patient as representative in further data interpretation. On the other hand, all subdomains showed high satisfaction scores. Oral functionality was the highest among fully satisfied patients, especially among Class III patients. Social implications also showed a good result with an overall score of 5.36. Awareness impact showed a similar result. Despite also achieving a good satisfaction score, higher patient concern was found in the aesthetic impact category. Figure 3 analyzes the impact of VSP modifications on satisfaction outcomes for all patients studied. Figure 3A shows the overall satisfaction levels of the cohort. Figure 3B shows the overall cohort data grouped by VSP following. No difference was observed between VSP followers and modified planning patients in any OQOL domain. Similarly, the same characteristic was observed for Class II (Figure 3C) and Class III (Figure 3D) patients, who also showed no differences between VSP-followed and -modified patients. Overall, all patients showed similar satisfaction levels regarding surgical performance, regardless of whether the procedure adhered to the initially proposed VSP. \begin{table}
