ABSTRACT

Orbital fractures alone represent 10% up to 25% of all facial fractures, but when they are associated with other fractures of the middle-third of the face, their incidence can increase up to 55%. This study aimed to identify whether the size of the orbital defect based on the classification by Jaquiéry et al. influenced the resolution of post-traumatic complications after orbital wall reconstruction using PRECLUDE®MVP alone or in combination with a titanium mesh or autogenous bone graft. Thirty-five orbits were categorized into four groups on the basis of the size of the defect and the operative techniques: group 1 contained 16 Jaquiéry class I orbits treated only with PRECLUDE®MVP; group 2 included eight class II orbits treated with PRECLUDE®MVP along with autogenous bone graft harvested from the calvaria or a titanium mesh; group 3 included five class III orbits and group 4 included six class IV orbits that were treated the same way as those in group 2. Spearman correlation showed that the use PRECLUDE®MVP didn't improve the post traumatic complications for big orbital defects due to the three-dimensional anatomical changes that occurred by neurologic lesions and lipolysis of the orbital contents.

ABSTRACT

Nowadays the reconstruction of craniofacial defects can be performed with different kinds of materials, which include the bone and the so-called biomaterials, which have the advantage of not needing a surgical site donor. Among these materials, great attention is given to polymers. In this large group, current attention is focused on the castor oil polymer, since this polymer is biocompatible, low cost, and has adequate strength for reconstruction of the craniomaxillofacial complex. This study aims to report the use of a prosthetic castor oil polymer for reconstruction of extensive defect, caused by a trauma, in the temporoparietal region.

ABSTRACT

A descoberta dos bisfosfonatos (BFs) como fármacos relacionados à inibição da reabsorção óssea os consagrou para o tratamento de pacientes portadores de osteoporose e de neoplasias com metástases ósseas, o que culminou com o seu uso ampliado. O presente trabalho tem por objetivo expor a importância da identificação dos pacientes que fazem uso dos BFs contribuindo assim para o adequado conhecimento sobre os riscos de complicações que acometem esses pacientes. O trabalho enfoca o emprego clínico dos BFs, os riscos que representam para os ossos da face, consideradas as suas características, bem como a importância de diagnosticar pacientes que fazem uso desses fármacos, a fim de orientá-los sobre o adequado tratamento odontológico a ser realizado, e desta forma contribuir para a redução da complicação que tem evolução imprevisível e consequências devastadoras para os pacientes.


The bisphosphonates (BFs) as a drug-related inhibition of bone resorption consecrates its to the treatment of patients with osteoporosis and cancer with bone metastases, which culminated with its expanded use. This study aims to explain the importance of identifying patients who make use of BFs thereby contributing to the adequate knowledge on risks related to these complications affecting patients. This study focuses on the clinical use of BFs, the risks it represents to the facial bones, considered its characteristics as well as the importance of diagnosing patients who use these drugs, in order to conduct them on the proper dental treatment to be held initially, and thus, to contribute to the reduction of complication that means an unforeseeable and devastating consequences for the patients.
