Hemifacial microsomia (HFM) is a rare, multisystemic congenital disease with estimated frequency of 1/26370 births in Europe. Most cases are sporadic and caused by unilateral abnormal morphogenesis of the first and second pharyngeal arches. The aim of this study is to define the types and frequency of maxillofacial and systemic malformations in HFM patients. This is a case series study of patients with HFM evaluated at a single institution. Data were acquired through history, physical examination, photographs, diagnostic radiology, and laboratory and analyzed by the FileMakerPro database on 95 patients (54F; 41M) of which 89 met the inclusion criteria...

BACKGROUND: Evaluations are important for teaching courses and contribute to educational quality assurance. CMF surgery provides a module in the skills-lab week in preparation for surgical clerkship. Even though the CMF module receives positive evaluations, the students report deviating content. Subsequently, exams skills were often not mastered correctly. The aim of this study is to gather the contents taught within the course and to revise the module accordingly. METHODS: A structured evaluation sheet was used to evaluate the CMF modules...

PURPOSE: Nowadays, in orbital wall reconstruction, maxillofacial surgeons have the possibility to treat patients in modern ways such as with individual implants. Nevertheless, conventional treatment including standard titanium mesh shaped during the surgical procedure is also widely used. The aim of this study was to compare the above methods of orbital wall reconstructions. MATERIALS AND METHODS: In the first group (39 cases), patients were treated by means of computer-aided design/computer-aided manufacturing (CAD/CAM) milled individual implants made of ultra-high-molecular-weight polyethylene, dioxide zirconium and rapid prototyping titanium mesh pre-bent on an ABS model made by a three-dimensional (3D) printer...

In patients with fractures of the zygomatic complex, computed tomography (CT) often identifies extensive defects in the orbital floor. Some surgeons recommend routine exploration and repair of these defects during repair of the zygoma, while others advocate a more selective approach, but there is a paucity of evidence either way. We report a retrospective case series of 50 patients who had open reduction and internal fixation of zygomatic fractures by a single surgeon in the maxillofacial department at the John Radcliffe Hospital, Oxford, between 2011and 2014...

The paper presents statistical data on implant placement procedures in Central Research Institute of Dentistry and Maxillofacial Surgery (Moscow, Russia) in 2010-2015. In 64% of cases inadequate bone volume was attributed to alveolar bone atrophy. Bone deficiency was equally often in upper and lower jaws (in 49.3 and 50.7%, correspondently) but varied in forms with complex configurations to be more specific for maxilla. The study also includes a series of clinical cases illustrating implant placement procedures in anatomically unfavorable settings...

Oral and maxillofacial fungal infections can appear in high-risk patients, including those immunocompromised. This article explores common oral manifestations of fungal infections in the oral cavity as primary lesions or as a result of disseminated disease. By far the most common oral fungal infection experienced in dentistry is oral candidiasis, which is reviewed in depth from simple oral infections to invasive candidiasis. The review aids the dental practitioner in understanding the full scope of Candida infections and other fungal infections...

REVIEW
Christopher F Viozzi
Sports account for 3% to 29% of facial injuries and 10% to 42% of facial fractures. Fractures of the facial skeleton most commonly occur owing to interpersonal violence or motor vehicle crashes. Facial fractures from sporting activities has clearly decreased over time owing to better preventive measures. However, this decreasing trend is offset by the emergence of more dangerous sports activities, or "pushing the envelope" of traditional sports activities. Fractures can occur from contact between athletes, and between athletes and their surroundings...

Carcinoma follows a course of multiple changes that are affected by several important factors, with epigenetic silencing of the promoter gene being one of them. A series of studies have suggested that epigenetic changes in the anti-aging gene Klotho may be one of the emerging areas of concern in the study of carcinogenesis. We hypothesized that epigenetic silencing of Klotho due to hypermethylation of DNMT3a may be one of the causes of carcinoma in the oral and maxillofacial region. In this study, we analyzed the immunohistochemical expressions of Klotho and DNMT3a in tissues obtained from oral dysplasia and oral squamous cell carcinoma...

Herein, an awkward case of globe perforation with a bullet-entering from the right posterior scapular region and leaving the body from the right orbit through the eye - is reported. Route of the bullet could be devastating - as it passed through the neck and the maxillofacial region-however by chance no vital damage occurred. Its path was assessed by plain radiography and computed tomography scans. Sometimes prediction of the trajectory is very difficult without additional radiological investigations. Especially, in the case of any high velocity projectile wounding, physician must be aware of the fact that the bullet's course will not be a linear but most probably a complicated one...

Hypnosis is a valuable tool in the management of patients who undergo surgical procedures in the maxillofacial complex, particularly in reducing and eliminating pain during surgery and aiding patients who have dental fear and are allergic to anesthesia. This case report demonstrates the efficacy of hypnosis in mitigating anxiety, bleeding, and pain during dental surgery without anesthesia during implant placement of tooth 14, the upper left first molar.

An oral lesion as the first clinical presentation of sarcoidosis is extremely rare. We present the case of a 39-year-old woman who was referred to the oral and maxillofacial surgery department with a persistent asymptomatic nodular lesion in the hard palate. This was located adjacent to a grossly carious upper first molar and a provisional diagnosis of chronic periapical granuloma was made. An incisional biopsy of the lesion was carried out, which unexpectedly revealed the presence of a non-caseating granulomatous inflammatory reaction...

War injuries are the cornerstone of maxillofacial surgery, and it led to the initiation and development of this specialty, and each case represents a challenge to the surgeon who deals with it. In this article, we present a 30-year-old male patient who was referred to our emergency department complaining of gunshot wound, severe pain, and limitation in mouth opening. Preoperative imaging showed a bullet with a very long path lodged in the infratemporal fossa. Three different approaches with the aid of C-arm imaging system were used for the removal of this bullet; the last approach was the successful one...

INTRODUCTION: Three-dimensional (3D) planning in oral and maxillofacial surgery has become a standard in the planification of a variety of conditions such as dental implants and orthognathic surgery. By using custom-made cutting and positioning guides, the virtual surgery is exported to the operating room, increasing precision and improving results. MATERIALS AND METHODS: We present our experience in the treatment of craniofacial deformities with 3D planning. Software to plan the different procedures has been selected for each case, depending on the procedure (Nobel Clinician, Kodak 3DS, Simplant O&O, Dolphin 3D, Timeus, Mimics and 3-Matic)...
