BACKGROUND: Oromandibular dystonia is a movement disorder that is characterized by involuntary masticatory and/or lingual muscle contracture. Jaw closing dystonia, the most common subtype of this condition, can cause trismus and is frequently misdiagnosed as temporomandibular joint disorder or masticatory muscle tendon-aponeurosis hyperplasia. MATERIALS AND METHODS: This report describes the long-term results of 18 patients with limited mouth opening (mean maximal mouth opening: 12...

BACKGROUND: The available referential measures defining the zygomatic bone morphology are adequate enough for full determination of the zygoma positioning, especially for trauma surgery, but osteometric analysis of the zygoma positioning based on tomographic examinations could be useful in peroperative and postoperative imaging. In this study, we propose referential measures, taking into account the morphology and the symmetry of the zygoma. In addition, the reliability and reproducibility are considered...

In the craniofacial bone field, fibrin sealants are used as coagulant and adhesive tools to stabilize grafts during surgery. Despite this, their exact role in osteogenesis is poorly characterized. In the present study, we aimed to characterize the osteogenic potential of TISSEEL fibrin sealant and used its technology to incorporate growth factors within its matrix. We focused on recombinant human bone morphogenetic protein (rhBMP)-9, which has previously been characterized as one of the strongest osteogenetic inducers in the BMP family...

INTRODUCTION: Maxillomandibular transverse osteodistraction (MMTOD) is an alternative approach to the traditional treatment for transverse maxillary and mandibular deficiencies and crowding. The aim was to report soft and hard-tissues changes and airway volume variation. METHODS: In this study, skeletally mature, non-syndromic patients with transverse maxillary and mandibular hypoplasia, who underwent a MMTOD between 2010 and 2012, were included. Surgical changes were analysed using clinical evaluation, three-dimensional facial surface data and computed tomography analysis before (T0) and after the completion of post-op orthodontic treatment (T1)...

Paragangliomas of the head and neck region are rare and predominantly asymptomatic tumors. These neoplasms arise from widely distributed paraganglionic cells, which originate from both mesodermal elements of third branchial arch and the neural crest residues. Despite the rare occurrence of paragangliomas, problems encountered in their diagnosis, unclear malignancy and treatment ensure that they still remain in the focus of head and neck surgeons. This is a retrospective study of the medical records of patients treated in the ENT Department of the 5th Military Hospital in Krakow during the period 2010-2014...

Recent studies indicated a lower osteogenic differentiation potential of adipose tissue-derived stromal cells (ASCs) compared to bone marrow derived mesenchymal stromal cells. The aim of this study was to evaluate the effects of potent combinations of highly osteogenic bone morphogenetic proteins (BMPs) in order to enhance the osteogenic differentiation potential of ASCs. Human ASCs were cultured for 10 days in the presence of osteogenic medium consisting of dexamethasone, ß-glycerophosphate and ascorbat-2-phosphate (OM) supplemented with BMP-2, BMP-6, BMP-9+IGF-2 and BMP-2,-6,-9 (day 1+2: 50 ng/ml, days 3-6: 100 ng/ml, days 7-10: 200 ng/ml)...

PURPOSE: Three-dimensional quantification of asymmetry in UCH has not been reported yet, but would be useful for diagnosing and evaluating the degree of deformity in this disease. It enables profound decision-making and timing of surgery. Unilateral condylar hyperplasia (UCH) can subjectively be classified in hemimandibular elongation (HE), hemimandibular hyperplasia (HH) and a combination of these two (hybrid form). The main purpose of this study was to quantify mandibular asymmetry in UCH patients with a reliable and reproducible method...

INTRODUCTION: Septic arthritis of the temporomandibular joint (TMJ) is a rare condition known to result in significant morbidity if diagnosis is delayed. Acute otomastoiditis is a typical complication of acute otitis media but few cases of acute otomastoiditis complicated with TMJ arthritis have been reported in the international literature. Furthermore, otomastoiditis reports and studies rarely analyzed TMJ CT scans. The aim of this study was to determine the incidence of TMJ arthritis in acute otomastoiditis, based on the analysis of CT scans...

BACKGROUND: Recent advancements in computed tomography have enabled the diagnosis of naso-orbito-ethmoid (NOE) fractures to be made in much greater detail. Surgical access to the upper nasofrontal buttress in NOE fractures, however, has remained unchanged over the past decades. All approaches to these fractures using skin incisions have individual drawbacks. The transcaruncular approach is free of the drawbacks of the cutaneous approaches. We further extended the transcaruncular approach for the treatment of NOE and Le Fort II fractures...

The use of virtual surgery, patient-specific saw and drill guides, and custom-made osteosynthesis plates is rapidly spreading from deformity surgery to orthognathic surgery. Most of the commercially available systems are using computer-aided design/computer-aided manufacture (CAD/CAM) wafers to produce patient-specific saw guides. However, most plate systems provided are still the conventional "in stock" mini plates that can be individually designed by pre-bending according to the stereolithographic model of the patient...
