| Statement of Problem: The main aim of advancement genioplasty is soft tissue and hard tissue stability which is important in improvement of the patients' aesthetics.Purpose: The evaluation of the soft and hard tissue stability in advancement genioplasty was the aim of this study.Materials and Method: The subjects in this study were 15 patients who prese-nted with retrognathia. All of the 15 patients underwent advancement geniop-lasty alone to correct retrognathia. The soft and hard tissue pogonion in pre-operation, immediately post-operation, and 18 months after operation in two groups of 9 patients with genial advancement less than 7mm (means 5.22mm) and 6 patients with genial advancement equal or greater than 7mm (means 7.16mm) were assessed.Results: After operation, no patient had infection or dehiscence and bone insta-bility. In group 1 with advancement less than 7mm, hard tissue pogonion relap-se was 0.60±0.66mm and soft tissue pogonion relapse was 1.55±0.46mm. In group 2 with advancement equal or more than 7mm, hard tissue pogonion rela-pse of 1.6±0.46mm and soft tissue pogonion relapse of 1.8±0.68mm were observed.Conclusion: Advancement genioplasty is a predictable operation specially when using rigid fixation. In this study, the result of operation in an 18 month period was stable. | ||
