    Histological and radiological changes in cranial bone in the presence of bone wax
    (2011) RAPOSO-AMARAL, Cassio Eduardo; ALMEIDA, Ana Beatriz Albino de; PASCHOAL, Gustavo; BUENO, Daniela Franco; VULCANO, Luiz Carlos; PASSOS-BUENO, Maria Rita; ALONSO, Nivaldo
    Purpose: To quantify the amount of bone formation in the calvarial region of Wistar rats after craniotomy using bone wax as a haemostatic agent. Methods: Surgery to produce bilateral, symmetric, full-thickness cranial defects (area: 18 mm(2)) was performed in eight animals. The right side of the cranium remained open and the edges of the left side osseous defect was covered with bone wax. Calvaria were imaged immediately after surgery and 12 weeks postoperatively by computerized tomography. The areas of the bone defects were measured in three-dimensional images using Magics 13.0 (Materialise-Belgic, software CAD). Results: The average amount of bone formation on the left and right side respectively was 4.85 mm(2) and 8.16 mm(2). Statistically significant differences between the amount of bone formation on the left and right sides were seen. Conclusion: Bone wax significantly diminishes the rate of bone formation in calvarial defects in a rat model.

    Modified technique to increase nostril cross-sectional area after using rib and septal cartilage graft over alar nasal cartilages
    (2012) WULKAN, Marcelo; SA, Alvaro Julio de Andrade; ALONSO, Nivaldo
    PURPOSE: Describe a modified technique to increase nostril cross-sectional area using rib and septal cartilage graft over alar nasal cartilages. METHODS: A modified surgical technique was used to obtain, carve and insert cartilage grafts over alar nasal cartilages. This study used standardized pictures and measured 90 cadaveric nostril cross-sectional area using Autocad (c); 30 were taken before any procedure and 60 were taken after grafts over lateral crura (30 using costal cartilage and 30 using septal cartilage). Statistical analysis were assessed using a model for repeated measures and ANOVA (Analysis of Variance) for the variable ""area"". RESULTS: There's statistical evidence that rib cartilage graft is more effective than septal cartilage graft. The mean area after the insertion of septal cartilage graft is smaller than the mean area under rib graft treatment (no confidence interval for mean difference contains the zero value and all P-values are below the significance level of 5%). CONCLUSIONS: The technique presented is applicable to increase nostril cross section area in cadavers. This modified technique revealed to enhance more nostril cross section area with costal cartilage graft over lateral crura rather than by septal graft.
