Avaliação radiográfica de enxerto secundário em fissura labiopalatal.

Abstract

Objectives: Through a measurement created by Witherow in 1999, it aimed to classify the secoundary graft and evaluate the bone gain based on the performed procedures at Fundação para Reabilitação de Deformidades Crânio-Faciais in the Lajeado’s town – RS that with unilateral cleft lip and palate patients between the years of 2008 to 2015. Materials and Methods: It has selected 71 patients with unilateral trans-foramen fissure, who performed a secondary bone graft with autogenous bone. Using two-dimensional X-ray images, it has evaluated the pre-surgical, post-immediate and follow-up images of the first and second year by three observers. Results: The Kappa values have shown alpha value >0,70 for intra-observer and medium alpha >0.896 for inter-observer. In the first year, 69% of the patients have been categorized in the A, 1% in B, 18,3% in C, 11,6% in E and 2% in F. In the second year, 58,7% of the patients have kept in the category A, 0,9 in B, 17,4% in C, 5,2% in D, 4,7% in E and 11,7% in F. Conclusion: There was an increase in the bone failures from year to another, although the proliferation prevalence and the grafted bone gain at cleft site have been kept. The use of categories is favorable to have a control over the bone gain after secondary graft.
