Pseudoaneurysm of Facial Artery After Orthognathic Surgery.

Sagittal osteotomy of the mandibular branch is to be included common approach for alteration of facial tooth shapes and it is treated technically safe. This conduct can breed various complications, among other things vascular complications. A clinical case has described the development of pseudoaneurysm in the facial artery in a 33-year patient undergoing bilateral osteotomy Le Fort I sagittal osteotomy of the mandibular branch.

Bilateral alloplastic prostheses for temporomandibular joint reconstruction in a patient with ankylosing spondylitis.

Ankylosing spondylitis (AS) or Bechterew disease is a chronic, usually progressive, systemic inflammatory joint disease, which predominantly affects the spine and sacroiliac joints. In these joints, early inflammatory changes are followed by lumbosacral pain and progressive restriction of spinal movement associated with radiologically visible intervertebral ossification. Peripheral joint involvement occurs in 10 to 30% of patients and shows a predilection for the shoulders, knees, ankles, feet, and wrists.

Evaluation of in vitro resistance of different 2.0-mm titanium plates on the mandibular angle sectioning.

Objective: The purpose of this study was to compare, by mechanical in vitro testing, a regular 5-hole plate and a long 4-hole plate with a regular 4-hole plate, applied to stabilize a simulated mandibular angle fracture.

Study Design: The plates from the 2.0-mm titanium-based system were adapted and stabilized passively in the same site in both groups using four screws, 6 mm long.

Determination of relative in vivo osteoconductivity of modified potassium fluorrichterite glass-ceramics compared with 45S5 bioglass.

Potassium fluorrichterite (KNaCaMg(5)Si(8)O(22)F(2)) glass-ceramics were modified by either increasing the concentration of calcium (GC5) or by the addition of P(2)O(5) (GP2). Rods (2 × 4 mm) of stoichiometric fluorrichterite (GST), modified compositions (GC5 and GP2) and 45S5 bioglass, which was used as the reference material, were prepared using a conventional lost-wax technique. Osteoconductivity was investigated by implantation into healing defects in the midshaft of rabbit femora.

Evaluation of osteoconductive and osteogenic potential of a dentin-based bone substitute using a calvarial defect model.

The aim of this study was to assess the osteoconductive and osteogenic properties of processed bovine dentin using a robust rabbit calvarial defect model. In total, 16 New Zealand White rabbits were operated to create three circular defects in the calvaria. One defect was left unfilled, one filled with collected autogenous bone, and the third defect was filled with the dentin-based bone substitute.

Temporal abscess after third molar extraction in the mandible.

Background: Dental infections resulting before or after third molar removal are complications in which the maxillofacial surgeon may have to initiate an earlier management. The severe dental infections resulting before or after this procedure is one of the few life-threatening complications in which the maxillofacial surgeon may have to initiate an earlier management. Infections involving the temporal space are rare and infrequently reported.

Tomographic, histological, and immunohistochemical evidences on the use of N-butyl-2-cyanoacrilate for onlay graft fixation in rabbits.

Background: The bone tissue responses to Cyanoacrylate have been described in the literature, but none used N-butyl-2-cyanoacrilate (NB-Cn) for bone graft fixation.

Purpose: The aims of the study were: (a) to analyze the bone grafts volume maintenance fixed either with NB-Cn or titanium screw; (b) to assess the incorporation of onlay grafts on perforated recipient bed; and (c) the differences of expression level of tartrate-resistant acid phosphatase (TRAP) protein involved in bone resorption.

Materials And Methods: Eighteen New Zealand White rabbits were submitted to calvaria onlay grafting on both sides of the mandible.

Retropharyngeal and cervicofacial subcutaneous emphysema after maxillofacial trauma.

Introduction: Subcutaneous emphysema in the cervical region is a well-documented event that may occur secondary to tonsillectomy, dental treatment, oropharyngeal barotraumas, scaling and root planning therapy, punch biopsy, endotracheal intubation, orthognathic surgery, extraction of impacted teeth, or after maxillofacial trauma. After trauma episodes, subcutaneous emphysema may be caused by a maxillary antral wall fracture that occurs when air pressure is introduced into the fascial planes of the connective tissue. Retropharyngeal emphysema is a severe condition associated with traumatic aerodigestive tract injury and may be associated with life-threatening situations requiring prompt attention and diagnosis in order to prevent serious consequences.

Use of zoledronic acid in the treatment of Gorham's disease.

Gorham's disease (Gorham-Stout syndrome) is a rare condition of unknown etiology involving a localized endothelial proliferation of lymph vessels resulting in destruction with bone resorption. The syndrome is rarely seen in the facial skeleton and has a large variety of prognoses and treatments. A case of this syndrome in a 9-year-old boy is presented.

Metastatic adenocarcinoma involving several bones of the body and the cranio-maxillofacial region: a case report.

Malignant tumours that have metastasized to the oral and maxillofacial region from distant sites account for only 1% of all malignancies of the jaw. These metastatic tumours are most often located in the mandible, and the majority of these in the molar region. The most common primary sources of metastatic tumours found in the oral region are the lung, kidney and prostate gland for the males, and the breast, genital organs and kidneys for females.
