NCT ID: NCT06395077 Completed - Alveolar Cleft Clinical Trials

Diagnostic Efficiency of Low-dose Cone-beam Computed Tomography in Post-graft Evaluation.

Start date: May 26, 2021
Phase:
Study type: Observational

Evaluation of a Low-dose exposure CBCT protocol for post-graft evaluation of treatment of cleft patients

NCT ID: NCT06304376 Completed - Alveolar Cleft Clinical Trials

Evaluation of Shell Technique in Secondary Alveolar Cleft Grafting

Alveolar cleft
Start date: March 12, 2022
Phase: N/A
Study type: Interventional

This study aims to evaluate the sufficiency of Khoury shell technique for reconstruction of alveolar cleft. Khoury technique was carried out using cortical bone shell fixed away from alveolar bone using two micro-screws, which was harvested from anterior iliac bone crest. The gap between the shell cortical bone and the native alveolar bone was filled by cancellous bone which was harvested from anterior iliac crest bone. The whole graft was covered by collagen membrane. The volumetric bone gain of the defect was determined via CBCT.

NCT ID: NCT06294522 Completed - Alveolar Cleft Clinical Trials

Reconstruction of Nasal Floor for Three-dimensional Repair of Alveolar Cleft

Start date: July 20, 2023
Phase: N/A
Study type: Interventional

reconstruction of alveolar cleft with autogenous bone after elevation of mucoperiosteal flap and suturing of nasal floor and palatal flap

NCT ID: NCT05988086 Completed - Alveolar Cleft Clinical Trials

Double Closure of Nasal Layer in Alveolar Cleft Grafting

Start date: October 10, 2022
Phase: N/A
Study type: Interventional

The aim of this prospective study is to evaluate both clinically and radiologically the efficacy of using autologous platelets rich fibrin versus collagen membrane for nasal layer closure in secondary alveolar cleft repair.

NCT ID: NCT05941988 Not yet recruiting - Alveolar Cleft Clinical Trials

Partial Maxillary Expansion With Post Grafting Expansion vs. Pre Full Maxillary Expansion in Secondary Alveolar Cleft

Start date: September 20, 2023
Phase: N/A
Study type: Interventional

Intermediate grafting with both pre- and post- grafting maxillary expansion with time span after grafting 6-8 weeks for consolidation and final retention for 3 months after finalization of expansion will get the advantages of both techniques combined.

NCT ID: NCT05283005 Recruiting - Alveolar Cleft Clinical Trials

Alveolar Cleft Grafting by Double Iliac Bone Blocks Versus Iliac Spongy Bone From Anterior Iliac Crest

Start date: December 28, 2021
Phase: N/A
Study type: Interventional

Reconstruction of Alveolar Cleft Using Double Iliac Corticocancellous Blocks in comparison with the gold standard technique ( cancellous bone ) both from anterior iliac crest.

Alveolar Cleft Reconstruction Powered by

Start date: June 1, 2021
Phase: N/A
Study type: Interventional

More than four million children are born with birth defects worldwide every year and a million presenting with cleft lip and palate. Cleft lip and palate is a congenital defect of the lip alveolar and palate it's now recognized as a significant cause of infant mortality and childhood morbidity and included among global burden of disease initiative. In Uganda the estimated number of babies born with cleft lip and palate is 1100 per year Children with 75% of them having alveolar cleft which is a defect in the upper jaw (Maxilla arch). The secondary bone graft and gingivoperiosteoplasty have become the two popular approaches to bone generation in alveolar defect. These two methods have varying success rates; primary gingivoperiosteoplasty 50 to 60% and secondary bone graft is 87% but Gingivoperiosteoplasty is the preferred option to many African surgeons to obviate the need for bone grafting which is technically demanding, prolonging therapy with many procedures therefore poor compliance, also increasing treatment failure rate and has significant associated donor morbidity. This project is set out to address the challenge of bone regeneration in alveolar cleft and improve on the surgical outcome by the use of stem cell therapy. The objective of this study is to compare the outcome of umbilical cord blood stem cell transplant plus gingivoperiosteoplasty to conventional gingivoperiosteoplasty on timing and density of bone regeneration. 1.3. Hypothesis In this study we hypothesize that primary repair with gingivoperiosteoplasty the success rate can be improved or enhanced with the use of stem cell therapy in our setting. Alternative hypothesis: Autologous umbilical stem cells transplantation following gingivoperiosteoplasty results in better bone regeneration when compared to gingivoperiosteoplasty. Null hypothesis: Autologous umbilical stem cells transplantation following gingivoperiosteoplasty has no benefit on promoting bone regeneration when compared to gingivoperiosteoplasty alone. The study will be a case control pilot study conducted in Kiruddu National Referral hospital Kampala Uganda. 20 participants who will be neonates of either sex with unilateral cleft lip and palate will be recruited in the study. They will be split into two groups: group A will have the umbilicus cord and placenta blood collected at birth and group B will not have umbilical cord or placenta blood collected and will be designated as the Control group.

NCT ID: NCT04845308 Completed - Alveolar Cleft Clinical Trials

Radiographic Evaluation of Secondary Alveolar Bone Grafting in Patients With Alveolar Cleft

SABG
Start date: April 1, 2021
Phase:
Study type: Observational

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.
