Complex Orbital Fractures: Three-Dimensional Planning and Combined Surgical Approach
No full textNowadays the development of diagnostic imaging, surgical techniques, alloplastic materials, and surgical instruments has made possible a more accurate management of orbital fractures. The aim of the present study was the management of orbital fractures and the solution of particular cases. The use of high-resolution computed tomography makes possible to gain a better understanding of the complex orbit anatomical structure. Also endoscopy is a valid alternative for medial orbital wall fractures treatment. It gives high control of the fracture site and its reduction. When this technology is combined with 3-dimensional (3D) reformatted images, it allows us to reconstruct more accurately the orbital defects. The authors present their experience in complex orbital fractures treated with the aim of the 3D navigation using a preformed orbital titanium plate. Endosopical approach was used to control plate positioning
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Preliminary Results of Bone Regeneration in Oromaxillomandibular Surgery Using Synthetic Granular Graft
No full textTraumatic, neoplastic, inflammatory, or infective dental removal promotes a gradual resorption process of bone which leads to a “nonuse” atrophy of the alveolar ridges. Many techniques allows restoring an appropriate bone thickness, but nowadays the attention is focused on the use of natural or synthetic grafts. Numerous studies have been conducted to develop and test new synthetic materials. In this article, the authors report their experience using a synthetic bone substitute in combination with Platelet Rich Fibrin (PRF). This technique was applied in different zones of the maxillomandibular district. The procedure showed a very satisfying bone regeneration without important complications

A monolateral TMJ replacement under intraoral endoscopic assistance for jaw osteomielitis: a modified approach
No full textAlloplastic replacement has become a valid treatment for TMJ endstage disease. The Alkayat and Bramley pre-auricular approach combined with the submandibular incision are the current surgical approaches for TMJ surgery. The present study shows a modified approach using intraoral endoscopic assistance. A female patient affected by jaw osteomielitis with condylar detachment was treated with total left TMJ alloplastic replacement combined with a right TMJ arthroplasty. No subamandibular incision was performed and, subsequently, the risks for permanent or temporary damage to the marginalis mandibulae nerve and surgical submandibular scar were avoided. Postoperative CT-Scan evidenced a good prosthesis position. No complications occurred after two years of follow-up
Correlation between salivary gland cancer and chronic infections (HIV, HBV, HCV)
No full textAIM: The aim of this study was to find the possible correlations between the tumors of the minor and major salivary glands and chronic viral diseases such as HIV, HCV and HBV.
METHODS: From January 2002 until September 2009 110 patients (age: 21-82 years) were presented at our clinic with tumors of the minor and major salivary glands. Of these patients, 10 were part of a wider range of patients with HIV and/or HCV and/or HBV. Of these 9 were male and 1 female. The study of patients has been carried out collecting anamnestic data and a general objective examination of the lesions with the assessment of the appearance, shape, texture, size, mobility as compared to lower floors of swelling and tenderness. The ultrasound, magnetic resonance imaging (MRI) and cytological examination (FNAC) have completed the diagnostic pathway.
RESULTS: This study shows an interesting correlation between these infections and tumors of the salivary glands especially the benign, such as the adenoma pleomorphic, the Warthin’s tumor and cysts. The predominant lesion appears to be the pleomorphic adenoma with a rate of 40%, followed by the Warthin’s tumor with 20%, adenocarcinoma with 20%, the basal cell adenoma with 10% and epidermoid cysts with 10% .
CONCLUSION: In conclusion, we raise a question: could be this correlation extended to other chronic infections? To give evidence of this we present a final case report with a presumed correlation between malaria infection and adenoma pleomorphic of parotid gland
