OBJECTIVES: For decades, Erich arch bars have been a standard in establishing maxillo-mandibular fixation (MMF). While reliable, the approach risks sharps injury, consumes operating room time, and inflicts gingival trauma. Newer technologies including screw-based techniques and "hybrid" techniques have improved MMF by reducing sharps injuries and operating room time, but risk injury to tooth roots, nerves, and gingiva. This study aims to establish the application, strengths, and limitations of dental occlusion ties as a novel alternative in maxillo-mandibular fixation...

This article analyzes the role played by the ear, nose and throat (ENT) specialist in the diagnosis and treatment of the Obstructive Sleep Apnea Syndrome (OSAS). DIAGNOSIS: The instrumental methods of investigation of otolaryngology expertise are fiberoptic rhinolaryngoscopy and sleep endoscopy. To better define and treat OSAS it is essential to define location, extension and degree of obstruction. The major limitation of rhinolaryngoscopy is that it is conducted while the patient is awake...

Maxillo-facial prosthetics is an important and recognised sub-discipline of prosthodontics that forms a key component of postgraduate training programs. General dentists have a role to play in the management of maxillo-facial defect patients even though treatment usually requires a multidisciplinary approach in an institutional environment. Maxillo-facial prosthetic cases frequently present with complex histories but simple patient goals. The conservatively managed implant-retained auricular prosthesis, speech aid prosthesis and orbital prosthesis cases described in this report were completed in a postgraduate clinical residency program and highlight the intrinsic complexities, challenges and ultimately satisfaction related to cases of this nature...

BACKGROUND: Compromised wound healing in cranio-maxillo-facial surgery is a threat to the patient's rehabilitation. Therapy of chronic and/or infected wounds is time- and cost-consuming, burdensome and occasionally futile. Cold atmospheric plasma is a new approach that promises to overcome these limitations. The aim of this proof-of-concept study was to evaluate the clinical outcome of cold plasma irradiation in patients with impaired wound healing who are refractory to conservative wound therapy and/or revision surgery...

INTRODUCTION: 3D printing seems to have more and more applications in maxillofacial surgery (MFS), particularly since the release on the market of general use 3D printers several years ago. The aim of our study was to answer 4 questions: 1. Who uses 3D printing in MFS and is it routine or not? 2. What are the main clinical indications for 3D printing in MFS and what are the kinds of objects that are used? 3. Are these objects printed by an official medical device (MD) manufacturer or made directly within the department or the lab? 4...

INTRODUCTION: The goal in treating Hemifacial microsomia (HFM) is to improve facial symmetry, allow functional jaw movement, obtain stable occlusion, and achieve patient satisfaction. This study was planned with an aim to assess the outcome of simultaneous maxillomandibular distraction osteogenesis in hemifacial microsomia. MATERIAL & METHODS: Seven patients with hemifacial microsomia were included in this study and demographic data was obtained. Simultaneous maxillo-mandibular distraction was planned for correction of maxillary cant, vertical ramal lengthening and midline, by performing unilateral mandibular osteotomy in ramus and distractor fixation, a Le Fort I osteotomy, with fixation at contralateral zygomatic buttress and intermaxillary elastics...

Worn dentition, often accompanied by occlusion changes such as reduced vertical dimension, poses a big challenge to both diagnosis and treatment. Current established causes fail to explain the observed tooth wearing patterns, and the treatments based on the documented pathogeneses are often unpredictable and require frequent maintenance. From the perspective of stomatognathic system, we postulate that the role of maxillo-mandibular relation is a crucial part in the tooth wear progression patterns, and should be well addressed in treatment planning...

Nasal Natural Killer (NK)/T cell lymphoma, commonly mentioned in the literature as Lethal Midline Granuloma (LMG) is an unusual pathology of the oro-maxillo-facial region characterized by aggressive and progressive destruction of the face, nose, palate and pharynx. This disease is now classified as a T-cell lymphoma based on modern cytogenetics, immunologic and molecular studies. However, it is mentioned in various literatures by various names. Here, we present one such clinically diagnosed, histopathologically and immunologically confirmed case of LMG, designated as NK/T cell lymphoma in a 56-year-old male...

INTRODUCTION: The caseload of jaw osteomyelitis seem to have decreased considerably over the last fifty years thanks to the progress of oral hygiene, the appearance and the use of antibiotics, and early screening. 'Limited osteitis' remains frequent in general practice (alveolitis after dental extraction), but osteomyelitis is much rarer as evidenced by the lack of current literature and the low number of reported patients in the published series. The aim of this study was to analyze retrospectively all the cases of maxillo-mandibular osteomyelitis treated in a large academic department of Stomatology and Maxillofacial Surgery over a period of 6 years and to compare the results to data from the literature...

BACKGROUND: Journal ranking based on the impact factor (IF) can be distorted by self-citation. The aim of this study is to investigate the present status of self-citation in the plastic surgery journals and its effect on the journals' IFs. METHODS: IF, IF without self-citations (corrected IF), self-cited rate, and self-citing rate for 11 plastic surgery journals were investigated from 2009-2015, by reviewing the Journal Citation Report(®). The correlations of the IF with the self-cited rate and the self-citing rate were statistically assessed...

OBJECT: Reconstruction of a cranial vault defect is a frequent challenge in neurosurgery. Polyetheretherketone (PEEK) is used in many types of prostheses and has been employed for 10 years in our institution (University Hospital of Toulouse, France). The objectives of this study are to describe the benefits and drawbacks of reconstructing the cranial vault defect with a PEEK prosthesis. METHODS: Clinical data of the 37 patients who received a reconstruction with a custom-made PEEK prosthesis from 2007-2015 were retrospectively analysed...

Facial asymmetry requires multidisciplinary management. In some cases, predictable problems due to congenital abnormalities can be corrected by early orthodontic treatment. Orthodontics is nevertheless often part of an orthosurgical treatment plan. The solutions are conventional and familiar: maxillomandibular rotation osteotomy and genioplasty. Many cases can be treated in this way, but there is often persistent residual asymmetry due to loss of volume that is not corrected by these techniques. The use of maxillo-acial endoprostheses designed on the basis of three-dimensional craniofacial analyses can rebalance volumes simply and with due regard to the patient's anatomy...

Three-dimensional (3-D) printing or additive manufacturing, an advanced technology that 3-D physical models are created, has been wildly applied in medical industries, including cardiothoracic surgery, cranio-maxillo-facial surgery and orthopaedic surgery. The physical models made by 3-D printing technology give surgeons a realistic impression of complex structures, allowing surgical planning and simulation before operations. In orthopaedic surgery, this technique is mainly applied in surgical planning especially revision and reconstructive surgeries, making patient-specific instruments or implants, and bone tissue engineering...

Obstructive sleep apnoea syndrome (OSAS) is characterized by recurrent partial or complete pharyngeal collapses during sleep. The pathophysiology of OSAS is complex and multifactorial. Factors influencing upper airway patency include a reduction in upper airway dimensions that can result from both anatomical and functional alterations (obesity, fluid shift or maxillo-facial structural changes), and increased pharyngeal collapsibility owing to reduced neuromuscular compensation and lack of the pharyngeal protective reflex during sleep...

BACKGROUND: Programmed cell death-1 (PD-1) is a negative regulator of T-cell responses. Expression of PD-1 and its ligands PD-L1 and PD-L2 in chronic rhinosinusitis with nasal polyps (CRSwNP) is poorly studied. METHODS: Expression of PD-1, PD-L1, PD-L2, TGF-β, IL-5, and IL-10 mRNA was measured by real-time quantitative PCR on tissue homogenates of patients with CRSwNP (n = 21) and healthy controls (n = 21) and on primary epithelial cells. Disease severity was scored using the Lund-Mackay scores of maxillofacial computed tomography (CT) scans...
