Abstract :

Purpose: The present study was designed to evaluate the long term osseous and soft tissue changes twelve months after advancement genioplasty Materials and methods: This study was done on patients who had been treated successfully at a teaching hospital in South India. This is a retrospective study of 10 patients who underwent advancement genioplasty in combination with maxillary anterior segmental osteotomy. The study included 8 female patients and 2 male patients in the age group ranging from 24–35years . Lateral cephalometric radiographs were studied for immediate and twelve months post operative changes. The relapse rate for the pogonion(pg) and soft tissue pogonion(pg1) were evaluated. All patients were treated with rigid internal fixation and the relapse rate was correlated with the amount of advancement. Results: In our study the mean advancement of the pogonion with the mean movement of the soft tissue pogonion shows a ratio of 1:1. The mean horizontal relapse of hard tissue pogonion was 0.55mm to the soft tissue horizontal relapse of 1.75mm which shows a ratio of 1:3. Hard tissue pogonion shows a relapse rate of 6%when compared to the soft tissue pogonion relapse rate of 18%.These changes were hard to detect clinically. Relapse was not significant to the amount of advancement. Conclusion: The result of our study shows that the post operative relapse following advancement genioplasty was clinically insignificant. Advancement genioplasty is a stable surgical technique for the aesthetic enhancement of the lower facial skeleton when used in conjuction with rigid internal fixation.
