3D Radiographic Evaluation of the Long Terms Results of Secondary Alveolar Bone Grafting in Patients With Alveolar Cleft: Comparison of Early Versus Late Secondary Grafting SABG : Secondary Alveolar Bone Grafting
3D Radiographic Evaluation of the Long Terms Results of Secondary Alveolar Bone Grafting in Patients With Alveolar Cleft: Comparison of Early Versus Late Secondary Grafting SABG : Secondary Alveolar Bone Grafting
Study about the comparison of post-operative results of secondary alveolar grafts according to two age groups: early secondary (4 to 7 years) versus late secondary (8 to 11 years) using a recently proposed score based on post-operative 3D CT analysis.
Comparison of the initial results of the graft in the two groups, with a reference 2D score and evaluation of the concordance between the results found with this score and those of the 3D score.
Finally, comparison of graft bone densities and nasal floor level (using 3D visualization) on post-operative TDMs in the 2 groups.
The aim of this study is to determine the optimal age for grafting using three-dimensional CT assessment.
Inclusion criteria:
- Patients operated with an alveolar bone grafting for a single or bilateral labio-alveolar cleft in the pediatric plastic surgery department of the University Hospital of Montpellier between 1999 and 2021 and having had 3D imageries defined as:
Group 1:
o Patients operated with an early secondary alveolar grafting between the ages of 4 to 7 years with a 3D imaging (CT, CBCT or scan) performed between the ages of 8 to 11 years.
Group 2:
