Introduction: The study of graft donor sites, whether from the anatomical, physiological or morphological point of view, has become a topic of current interest, due to the increasing number of patients needing facial bone reconstruction for various reasons. Purpose: In view of the need to constantly improve surgical techniques for autogenous bone graft harvesting, still considered the best choice for facial bone reconstruction, this paper describes an anatomical study on dry skulls in order to evaluate the average thickness of the parietal bone. Material and Methods: Measurements of this bone were taken with a goniometer, at four previously defined points, in the region that is often used as a donor site, in 49 dry skulls (98 parietal bones). The results were evaluated using the T test. Results: Thickness was measured at four predetermined points. The mean values (Point A = 4898mm, B = 4517mm, C = 6185mm, D = 4280mm) show that the bone can be even thinner than previously reported in the literature in other studies of the same nature. The largest bone thickness is in the medial and posterior region. Conclusion: A knowledge of these anatomical characteristics is helpful in preventing possible surgical complications, as well as making it safer for the surgeon to remove this graft and providing more information on whether or not to indicate this region as a bone graft donor site.

A perda embrionária consiste em perda econômica significativa dentro do processo de criação de equinos e representa custos adicionais para os criadores decorrentes das repetidas coberturas de éguas durante a temporada reprodutiva, além da diminuição do número de potros nascidos. São consideradas perdas embrionárias aquelas que ocorrem até o 49º dia da gestação e são decorrente de diversos fatores maternos e/ou embrionários. Atualmente, com a utilização da ultrassonografia, pode-se observar a vesícula embrionária a partir do 11º dia pós-ovulação, sendo possível o diagnóstico precoce de tais perdas. Devido ao grande prejuízo econômico na reprodução equina decorrente de perdas gestacionais, o objetivo deste Trabalho de Conclusão de Curso foi realizar revisão de literatura sobre as principais causas da perda embrionária em éguas

Objectives: The aim of this study was to evaluate the behavior of the polymer histomorphometrically castor during the healing process of defects of critical size calvarial preparations in rats. Materials and Methods: Twenty animals underwent a surgical procedure that was to be held in the calvaria of each animal a critical defect of 8 mm in diameter with a drill trephine. The rats were divided into two groups according to the following procedures: group C received no treatment and the bone defect site was filled with blood clot, group M, the bone defect was filled with castor oil polymer particles. The animals were sacrificed 180 days after the surgical procedures. After routine laboratory procedures the specimens were subjected to analysis histomorphometric. Results: In groups C the newly formed bone tissue was well developed, with adjacent areas of osteoid matrix rich in osteoblasts, and restricted to the vicinity of the edges of the defect. In animals of group M was observed newly formed lamellar bone tissue restricted to the vicinity of the defect edges and particles of polymer Castor distributed throughout the defect. There was a higher percentage of newly formed bone area was statistically significant in group C compared to animals in group M. Conclusions: Within the limits of this study can conclude that the castor oil polymer is biocompatible and had kept the area during the healing of critical size defects in surgically prepared rat calvariae.
