[ 10 ] - Treatment of a Mandibular Fracture by Two Perpendicular Mini-Plates
Introduction: In open reduction and internal fixation for the treatment of mandibular fracture, the fixation technique used is very important in reducing post-operative complications and promoting the healing process. This study assessed the results of fixation of the mandible using two mini-plates perpendicular to each other in the lower border of the mandible for fracture treatment. Materi...
[ 11 ] - Submental Artery Island Flap in Reconstruction of Harde Plate after wide Surgical Resection of Veruccous Carcinoma. Two case reports
Introduction: Reconstruction of intraoral soft tissue defects is important in restoring function and esthetic. In large defects, there will be demand for regional pedicle flaps or free flaps. Hard palate separates nasal and oral cavities. Due to the small surface area between flap and remaining palate after surgical resections, optimal blood supply of the flaps for hard palate reconstructions ...

Materials and Methods: Submental intubation was performed in twelve patients with maxillofacial trauma ,from 2007 – 2012, which were operated under general anesthesia for treatment of facial fractures. Results: The pati...
[ 13 ] - A Bilateral Pediculated Palatal Periosteal Connective Tissue Flap for Coverage of Large Bone Grafts in the Anterior Maxillary Region
Introduction: Coverage of bone grafts is very important in reconstructive surgery. In edentulous alveolar ridges this coverage is particularly important for supporting dental prostheses. Here we present the case of a patient with a large deficient maxillary anterior region that was reconstructed with a bilateral palatal submucosal periosteal connective tissue flap: a soft tissue reserve for up...
[ 14 ] - A Schwannoma of the Soft Palate in a Child: Histological and Immunohistochemical Features and Surgical Method
Introduction: Schwannoma, or neurilemmoma, is a benign neoplasm of Schwann cells that is extremely rare in the soft palate.

[ 20 ] - Apical Force Application in the Management of Dentoalveolar Fractures: Indications, Procedure and Limitations
Dentoalveolar fracture is defined as a fracture in the bone surrounding the teeth without any extension to the basal bones of the maxilla or mandible (1). As for other parts of the facial skeleton, the treatment strategy for dentoalveolar fractures consists of fracture reduction, fixation and immobilization (2); however, some dentoalveolar fractures are difficult to treat. In some dentoalveola...
