The ossifying fibroma (OF) is an unfrequent fibro-osseous lesion that generally affects middle age woman, usually setting in the posterior area of the jaw. Clinically the patient can present a long-term asymptomatic swelling that generates teeth displacement as an early manifestation. Radiographically it is characterized for being a radiolucid lesion in its first stages, then it evolves to a mixed lesion with variable radioopaque areas and ends as an extremely radioopaque lesion. The treatment varies according to its size and it can vary from a conservative surgery to a block resection followed by reconstruction through a bone graft. We present a five years controlled case of a big size OF in a 22-year-old male patient. The specific clinical and histological characteristics are described. It is presented, according to the lesion extension, a therapeutic conduct with a block resection of the affected jaw segment with the posterior reconstruction through a free microvascular fibula flap. Four dental titanium osseointegrated implants were installed on the bone graft. The oral rehabilitation was made by an implant supported hybrid oral prosthesis associated to excellent, functional and aesthetic, results.

The methylmethacrylate was first synthesized in 1902 by Röhm, a German
chemical, and was patented by the name of Plexiglas in 1928. This alloplastic material had its first use, for medical purposes, in 1936 as dental prosthetics. In 1940 the methylmethacrylate was used to cover a major defect at the skull due to craniotomy. The use of methylmethacrylate at maxillofacial procedures it is basically as a fill material for facial defects, it can be used for maxillofacial trauma procedures, reconstructive procedures and even for orthognatic surgery, it is a safe material and your use usually do not promote side effect, due to its properties that are almost ideal, it is a chemically inert material, biocompatible, noncarcinogenic, low cost, easy to handle and stabilize, it does not alter its form or volume allowing a precise planning of the surgical procedure. The aim of this presentation is to show the versatile use of the methylmethacrylate in innumerous procedures of oral and maxillofacial surgery in a public service in Brazil. Conflict of interest: None declared.

gical intervention. The reduced airway passage required nasal fibroscopy intubation. The surgical strategy involved the exploration of the laterpharyngeal, retropharyngeal, submandibular and pterygomandibular spaces. A retromandibular incision was extended to submandibular and cervical region allowing the exploration of the submandibular, retromandibular and pterygoid region. Walter drains were placed. The patient remained intubated for 24 h post surgery. Seven days latter the patient presented pleural pulmonar effusion. This case illustrates the need for early surgical intervention and adequate post operative control. In the case of deep cervical infection spreading to the thoracic region. The occurrence of pleural effusion might be related to mediastinitis in a very early stage, successively be treated by wide cervical drainage. Therefore the oral surgeon should be alert towards the possibility of descending mediastinitis in deep cervical infection of dental origin. Conflict of interest: None declared.

Deep cervical infections may be of dental origin and cause life threatning conditions, including airway obstruction, mediastinitis and sepses. We report a 29 year old man with uncomfortable toothache in his right jaw, who presented deep cervical infection of dental origin. The patient was attended in the emergency department and complained of having a sore throat, dysfagia and dyspnea. The patient previously presented healthy and no underlying disease with the exception of presenting chronic alcohol abuse and smoking. Physical examination showed limited mouth opening, preauricular pain and infection of the first lower right molar. There was a difficulty towards visualizing the oropharynx. The case was diagnosed as Ludwig’s Angina. There was the need for sur-

Oral and maxillofacial surgery is a branch of dentistry responsible for diagnosing and treating diseases, deformities and injuries of oral and maxillofacial region, including those that involve both hard and soft tissues. In Venezuela the teaching of this specialty is relatively young, there are currently two masters responsible for the teaching of this discipline, one in Caracas and one in the city of Valencia. The purpose of this paper is to demonstrate the dynamics imparted by these postgraduate study and history through which they have been developed in order to make known the profile of future residents and Venezuelan expert, and the progress have achieved the same in accordance with international training standards.
