Bone Regeneration of the Maxillofacial Region Through the Use of Mesenchymal Cells Obtained by a Filtration Process of the Adipose Tissue.

In this work, the authors will discuss about a new protocol and rapid alternative to isolate the mesenchymal stromal cells from the stromal vascular fraction, without the use of collagenase, to regenerate the bone tissue in the maxillo-facial region. This method employs a device that allows the isolation and concentration of stromal vascular fraction by means of lipoaspirates, which separate the lipid component and fragments of the extracellular matrix. The innovative element consists in using a filtration device instead of a centrifuging device to separate the different components.

Schwannoma of the parotid gland. Case report.

Schwannoma is encapsulated benign tumors arising from nerve cell. Of which ancient schwannoma is one of five variants. Intraparotid facial nerve schwannoma is been documented sporadical throught the medical literature, althought a few ancient schwannomas have been reported in different locations in the head and neck region.

Le Fort III osteotomic variants.

Introduction: Midface hypoplasia is a skeletal defect involving all three space planes, hence needing a three-dimensional repositioning. This research study shows two cases of cranio-facial dysostosis, on which two Le Fort III variants were performed.

Case Report: In the first case we report the performing the two types of osteotomy simultaneously.

Fronto-orbito-zygomatic trauma with eyelid involvement.

As part of the trauma of the upper third of the massive face, the fronto-orbito-zygomatic arch is the most frequent and is often associated with eyelid involvement. From 2001 to 2008, 135 patients with fronto-orbital eyelid complex alterations occurred at our center; the patients were included in clinical follow-ups until 2010. Most patients (80%) came to our observation in a state of emergency due to automobile accidents, sports injuries, or assaults, whereas a smaller proportion (20%) was because of previous trauma or surgery.

Biomaterial implantation in facial esthetic diseases: ultrasonography monitor follow-up.

Facial deficit diseases are corrected by biomaterial implantation. The ideal biomaterial should be easy to implant and remove and simple to be identified by a low-dose radiation and low-cost radiologic technique. The purpose of this work was to evaluate ultrasonography (US) as a technique in monitoring biomaterial status after operation.
