Treatment of Facial Asymmetry Using Distraction Osteogenesis in a Mandible First Approach.

Background: Facial asymmetry includes several etiologies, among them trauma to the condylar area during early childhood and congenital malformations such as hemifacial microsomia. This article describes the management of facial asymmetry in adolescents and young adults using a mandible first approach by distraction osteogenesis, followed by maxillary Le-Fort I as a second stage.

Methods: Eighteen patients 14-25 years of age presented with unilateral hypoplasia of the jaws which manifested clinically by deviation of the chin and canting of the occlusal plane.

A Comparative Study of Mucosal Wound Healing after Excision with a Scalpel, Diode Laser, or CO Laser.

Unlabelled: We aimed to compare the clinical and histological secondary healing effectiveness of various types of high-level laser versus scalpel excision in mucosa frenectomy.

Methods: Forty-five Sprague Dawley rats were used in this study. These rats were divided into two laser intervention groups (CO, n = 15; diode, n = 15) and one control group with scalpel excision (n = 15).

Kluri Anomaly: Newly Introduced Pancreatic Duct Anomaly.

Anomalies of the pancreas organ, especially congenital anomalies, are very uncommon, and can involve the pancreatic ductal as well as the pancreatic extra-ductal systems. While these anomalies usually present as an incidental radiological finding during adulthood, sometimes, they can present as recurrent upper abdominal pain as a presentation of recurrent episodes of acute idiopathic pancreatitis. Thus, these anomalies should be regarded in the differential diagnosis list, as a cause, for recurrent idiopathic pancreatitis, especially in the adult age group of patients.

Retroperitoneal Liposarcoma: The Giant Type.

Retroperitoneal tumors (RPTs) are very rare tumors that arise in the large space of the retroperitoneum. About two-third of these tumors are malignant, of which soft tissue sarcoma (STS) is the most common and comprises almost one-third of malignant RPTs. Twenty to thirty percent of RPTs are benign.

The Relationship Between Morphometric Measurements, Severity, and Success of Zygomatic Arch Fracture Reduction.

Purpose: Identify associations between preoperative radiographic measurements and clinical findings of zygomatic arch fractures and postoperative radiographic measurements. Based on those findings, propose a comprehensive treatment algorithm for the solitary zygomatic arch fracture and combined zygomatic arch-zygomatic complex fracture.

Methods: Retrospective cohort study with patients referred to our department for zygomatic arch fractures between 2013 and 2018.

Early antitumor activity of oral Langerhans cells is compromised by a carcinogen.

Early diagnosis of oral squamous cell carcinoma (OSCC) remains an unmet clinical need. Therefore, elucidating the initial events of OSCC preceding tumor development could benefit OSCC prognosis. Here, we define the Langerhans cells (LCs) of the tongue and demonstrate that LCs protect the epithelium from carcinogen-induced OSCC by rapidly priming αβT cells capable of eliminating γH2AX epithelial cells, whereas γδT and natural killer cells are dispensable.

The Relationship Between Morphometric Measurments, Severity and Success of Zygomatic Arch Fracture Reduction.

Purpose: Zygomatic arch fractures are commonly treated by closed reduction. This kind of treatment is highly influenced by the treating surgeon and type of fracture. Thus, it is important to choose the optimal treatment for different fractures.

Is Open Reduction Internal Fixation Using Titanium Plates in the Mandible as Successful as We Think?

Titanium plats are the gold-standard for fracture fixation. Titanium is considered biocompatible, corrosion resistant with an elasticity-modulus closest to bone. Nonetheless, titanium plates are not always as inherent as hoped.

A Protocol for Simple, Rapid, and Direct Detection of SARS-CoV-2 from clinical samples, using Reverse Transcribed Loop-Mediated Isothermal Amplification (RT-LAMP).

SARS-CoV-2 has quickly spread all around the globe causing illness and wide damages. Most countries were unprepared for such a rapid spread and crisis. This led to various strategies for effective control of the new pandemic.

Postextraction Mucormycosis in Immunocompromised-Patient Management and Review of Literature.

Purpose: Mucormycosis is an uncommon aggressive, opportunistic infection that can produce widespread orofacial tissue necrosis. This primarily affects immunocompromised individuals. It is the deadliest and most rapidly progressing type of human-affecting fungal infection.

Extramaxillary Zygomatic Implants: An Alternative Approach for the Reconstruction of the Atrophic Maxilla.

Background: Limited bone quality in the posterior maxilla results in low success rates for dental implants. Various bone augmentation methods have been described, yet most require two-step surgical procedures with relatively high rates of resorption and failure. An alternative for these patients is zygomatic implants.

3D Planning and Printing of Patient Specific Implants for Reconstruction of Bony Defects.

We are in the midst of the 3D era in most aspects of life, and especially in medicine. The surgical discipline is one of the major players in the medical field using the constantly developing 3D planning and printing capabilities. Computer-assisted design (CAD) and computer assisted manufacturing (CAM) are used to describe the 3D planning and manufacturing of the product.

Direct on-the-spot detection of SARS-CoV-2 in patients.

Humanity is currently experiencing a global pandemic with devastating implications on human health and the economy. Most countries are gradually exiting their lockdown state. We are currently lacking rapid and simple viral detections, especially methods that can be performed in the household.

Treatment of Facial Deformities using 3D Planning and Printing of Patient-Specific Implants.

Technological advancements in surgical planning and patient-specific implants are constantly evolving. One can either adopt the technology to achieve better results, even in the less experienced hand, or continue without it. As technology develops and becomes more user-friendly, we believe it is time to allow the surgeon the option to plan his/her operations and create his/her own patient-specific surgical guides and fixation plates allowing him full control over the process.

The Influence of Mandibular Gonial Angle on Fracture Site.

Purpose: The mandibular angle is influenced by multiple codependent morphologic dynamic factors, such as osseous anatomy, forces exerted by the muscles of mastication, occlusal loading patterns, and anatomic structures. These factors can influence the presence of a fracture in this area. Our research aimed to investigate a potential correlation between the risk of angle fractures and age, gender, fracture etiology, gonial angle size, presence of mandibular third molars, or presence of occlusal support.

Craniofacial Morphometric Features Associated With Pericondylar Fractures of the Mandible.

The research aimed at investigating potential correlations between craniofacial morphological measurements and mandibular pericondylar fractures, based on a retrospective study of 380 mandible fractures treated in our department, during 2010 to 2017. Predictors included morphological measurements and features. Primary outcome was presence of pericondylar fracture; 133 pericondylar fractures were found, including subcondylar, condylar neck, and condylar head fractures.

Bone Augmentation Techniques for Horizontal and Vertical Alveolar Ridge Deficiency in Oral Implantology.

Bone deficiency is the major obstacle in implant dentistry. Guided bone regeneration (GBR) with particulate bone and barrier membranes has been the primary surgical technique used to regenerate alveolar bone for dental implant therapy. This procedure has been used in implant dentistry for more than 30 years and continues to be developed and refined for more predictable surgical outcomes.

The Relation Between Morphometric Features and Susceptibility to Mandibular Angle Fractures.

The study was aimed to determine possible relations between skeletal morphologic parameters to mandibular angle fractures. Retrospective study of 100 patients suffering from mandibular fractures and treated in the Rambam Health Care Campus between the years 2013 and 2017 was conducted. Predictor variable was facial skeletal morphologic features as derived from the measurements.

Effects of Timing of Extracorporeal Shock Wave Therapy on Mandibular Distraction Osteogenesis: An Experimental Study in a Rat Model.

Purpose: Distraction osteogenesis (DO) is an established method for bone lengthening in the craniofacial skeleton. Its major drawback is the long consolidation period with attendant morbidity and possible complications. Several methods have been suggested to shorten the consolidation period.

Sandwich osteotomy for the reconstruction of deficient alveolar bone.

Alveolar bone deficiency is a very common problem encountered by the practitioner when planning dental implants. The severity of the deficiency is variable. Many practitioners perform augmentation using the method they feel comfortable with and do not necessarily use the most appropriate method.

Two-stage reconstruction of the severely deficient alveolar ridge: bone graft followed by alveolar distraction osteogenesis.

Distraction osteogenesis for the augmentation of severe alveolar bone deficiency has gained popularity during the past two decades. In cases where the vertical bone height is not sufficient to create a stable transport segment, performing alveolar distraction osteogenesis (ADO) is not possible. In these severe cases, a two-stage treatment protocol is suggested: onlay bone grafting followed by ADO.
