PURPOSE: The treatment of pathologic fractures in stage III medication-related osteonecrosis of the jaw (MRONJ) remains challenging. The treatment in the literature is controversial, varying from extensive and aggressive surgery with resections and musculocutaneous free flap reconstruction to conservative treatment with only mouth rinses and/or antimicrobial treatment. The purpose of this study was to analyse the results of the treatment protocol in the Leiden University Medical Center in the Netherlands...

PURPOSE: Ablative oncological surgery to treat head-and-neck cancer often triggers a requirement for jaw reconstruction. Modern surgical procedures using free microvascular flaps afford acceptable outcomes in terms of restoration of bony and soft tissue defects. A fibula free flap is often the preferred flap, as the bone length is considerable and a two-surgeon approach is possible. Dental implants play important roles in functional rehabilitation. Our aim was to evaluate the survival of dental implants placed in reconstructed areas after transfer of fibula tissue to the jaw...

Intra-Articular Temporo-Mandibular Disorders (TMD) are characterized by displacement of the disc that causes the condyles to slip back over the disc thus resulting in TMJ discal damage and erosion of the condyle's bone. The etiology of temporomandibular disorder (TMD) is multidimensional: biomechanical, neuromuscular, bio-psychosocial and biological factors may contribute to the disorder. The study involved 46 joints in 27 patients with a diagnosis of Intra-Articular Temporo-Mandibular Disorders (TMD) according to Axis I of Diagnostic Criteria for Temporomandibular Disorders (DC/TMD) for Clinical and Research Applications and underwent surgery between 2011 and 2014...

PURPOSE: Depending on the site and size of head and neck cancer, the disease affects patients' appearance and subsequently their quality of life. The aim of this study was to correlate subjective and objective evaluation of facial appearance and associated quality of life following ablative tumor surgery and microsurgical reconstruction. MATERIAL AND METHODS: A total of 99 patients with combined ablative and reconstructive microsurgical procedure for head and neck malignancy and seven patients with non-malignant disease were examined by three-dimensional (3D) (photogrammetry at least 6 months post-surgery and were evaluated by two-dimensional (2D) and 3D means for symmetry and facial proportions...

INTRODUCTION: Aim of this study was 1) to evaluate long-term dental/skeletal stability in patients with mandibular retrognathia corrected by BSSO, and 2) to examine factors associated with relapse. MATERIALS AND METHODS: Seventy-seven of initial 151 study cohort subjects who had undergone orthognathic surgery in 2007-2011 agreed to participate. Present paper presents data on dental/skeletal stability in 46 patients; 31 patients were excluded because of missing calibration indicator in one of the patients' pre-operative cephalometric radiographs, or because of pregnancy...

PURPOSE: Maxillary downgraft (MD) and mandibular setback (MS) are problematic procedures in terms of postoperative stability. While the amount of intraoperative clockwise rotation (CWR) of the proximal segment (PS) after MS combined with MD has a positive correlation with the amount of MD, mandibular relapse after MS with MD in relation to intraoperative CWR of the PS has not been reported. Moreover, the effect of mandibular relapse on maxillary stability after MS with MD remains unclear...

In consideration of the 3-R-rule (Refine-Replace-Reduce) as a guideline for promoting ethical use of animals for surgical training, we present a novel training model for microvessel anastomosis. In a rat cadaveric study, we evaluated the surgical anatomy of the common carotid artery (CCA), external jugular vein (EJV) and femoral vessels (FV) which were then used as templates for the present investigation. Anatomical dissection of 30 rat cadavers was performed. Two residents without prior microsurgical experience were included in the study and performed 5 CCA, 5 femoral artery, 5 EJV and 5 femoral vein anastomoses...

PURPOSE: Surgical skills can be improved through practical exercise. The use of specimens, human as well as animal, or live animals for surgical training is limited due to ethical concerns. Drawbacks of simulators are costs, fidelity and creditibility. Thus, simulators must be evaluated objectively to determine their validity before they can be used as teaching modalities. The aim of this study was to verify the face content and construct validity of a novel model-based simulator for lifting tabula externa transplants from the parietal skull...

Telemedicine enables us to push back the geographical and interactive boundaries of medicine. With a role in humanitarian missions, it is particularly pertinent at two key stages: the preparation phase, and at postoperative follow-up after the mission. It is our intention to describe our experience of telemedicine within a humanitarian context. Four teleconsultations were organized between departments of maxillofacial surgery in Caen (France) and in Bamako (Mali). 21 patients were assessed regarding their care...

Distraction osteogenesis (DO) has become increasingly popular to correct craniosynostosis. Disadvantages of DO include the secondary operation needed for device removal and titanium screw related dura injury. To reduce invasiveness of the secondary device removal operation and to overcome titanium-related problems, fixation of the cranial distractor with resorbable materials is a potential alternative. New resorbable fixation methods, such as ultrasound-activated pins (UAPs) or heat-activated pins (HAPs), allow faster attachment on thinner bone than conventional resorbable screws (CRSs) since tapping is not required...

Pierre Robin Sequence (PRS) combines mandible microretrognathia, asynchronism of the pharynx and tongue, glossoptosis and, in some cases, cleft palate. Its principal functional consequences are respiratory and feeding problems during the neonatal period. In this study, we focused on the impact of early closure of the cleft at six months on mandibular growth in patients with PRS. We performed a retrospective study of 15 patients followed for PRS and undergoing surgery performed by the same senior surgeon (HB) at our cleft center between 2005 and 2012...

This retrospective cohort study aimed to assess, three-dimensionally, mandible and maxilla changes following maxillomandibular advancement (MMA), with and without repositioning of TMJ articular discs. The sample comprised cone-beam computed tomography data from 32 subjects: group 1 (n = 12) without disc displacement and group 2 (n = 20) with bilateral disc repositioning. An automatic cranial base superimposition method was used to register the images at three time points: T1 (preoperative), T2 (postoperative), and T3 (at least 11 months follow-up)...

BACKGROUND: There is considerable controversy about whether condylar fractures should be treated open or closed. Even when there is a clear indication for open treatment, the appropriate approach opens another debate. PURPOSE: To provide a clear overview on the complications of extraoral approaches to condylar fractures. METHODS: Systematic literature search of all indexed years on PubMed, Medline, and Embase. For detailed analysis, we selected 70 studies...

INTRODUCTION: The optimal surgical technique for the management of patients with Robin Sequence (RS) has not been established. One of the most commonly used surgical techniques, mandibular distraction osteogenesis (MDO), is still controversial because of its potential risks and the lack of clear evidence of its efficacy. OBJECTIVES: To assess variations in airway patency, clinical symptoms, and polysomnographic parameters in children with RS who underwent MDO. METHODS: In this prospective cohort study, 38 patients with RS were evaluated before and after MDO...

BACKGROUND: Wide surgical access to the orbital floor and medial wall is often impaired by the course of the inferior oblique muscle. There is no current consensus on the optimal surgical approach for exposure, and techniques involving inferior oblique division are generally shunned for concern of possible complications. OBJECTIVE: To determine the safety and outcomes of inferior oblique division and reattachment for surgical access to the orbital floor and medial wall during orbital fracture repair...
