Evaluation of Different Patterns of Zygomaticoorbital Complex Fractures.

Study Design: Very few studies exist regarding the fracture pattern variability of the zygomaticoorbital (ZMO) complex. The retrospective evaluation of a large series of surgically treated unilateral ZMO fractures would in certain circumstances help intraoperative predictability and define sensitive indicators for open reduction and internal fixation.

Objective: The aim of this study was to investigate the different fracture patterns after ZMO complex injury regarding the 5 anatomic sutures of the zygoma as well as the concomitance of the paranasal buttress and maxillary sinus wall fracture.

Current standards in the diagnosis and treatment of oral squamous cell carcinoma - a multicenter analysis.

The German guideline for oral squamous cell carcinoma (OSCC) describes the recommended diagnosis and treatment procedures for OSCC and ensures the highest quality patient care. However, the current German guideline for OSCC is indistinct and therapy planning is not standardized in detail between centers. To address this, the current diagnostic and therapeutic strategies in different oral and maxillofacial surgery departments in Germany were summarized using a uniform questionnaire.

Prosthetically guided oral implant surgery. A retrospective cohort study evaluating the 5-year surgical outcome.

Purpose: This study primarily evaluated the 5-year implant survival and success rate of prosthetically guided inserted implants.

Tocilizumab: Another medication related to osteonecrosis of the jaws? A case report and literature review.

Medication-related osteonecrosis of the jaw (MRONJ) is a serious complication in patients receiving antiresorptive medication, such as bisphosphonates and denosumab, for different oncologic and non-oncologic diseases. Here, we report a case of MRONJ in a patient treated with tocilizumab, a humanized anti-interleukin-6 receptor antibody that effectively treats moderate to severe rheumatoid arthritis in adults. A 45-year-old female patient diagnosed with severe rheumatoid arthritis, who had been undergoing intravenous tocilizumab therapy for three years without history of bisphosphonate use, was referred to our department.

Eggerthia catenaformis infection originating from a dental abscess causes severe intestinal complications and osteomyelitis of the jaw.

Odontogenic foci may result to generalized infections spreading the bacteria through contiguous anatomic cavities or hematogenous spread. The most reported secondary infections caused by oral pathogens are intracranial abscesses. Although, few reports in the literature describe the bacterial spread to extracranial locations.

A novel histopathological scoring system for patients with oral squamous cell carcinoma.

Objectives: Tumor invasion into blood and/or lymphatic vessels, perineural invasion, and histopathological grading are evaluated to assess the biological aggressiveness of oral squamous cell carcinoma (OSCC). We aim to assess the prognostic impact of a novel scoring system, based upon the aforementioned histological parameters.

Materials And Methods: Retrospective chart review of 334 patients with treatment-naive squamous cell carcinoma of the oral cavity.

Craniomaxillofacial patient-specific CAD/CAM implants based on cone-beam tomography data - A feasibility study.

Customized implants have simplified surgical procedures and have improved patient outcome in craniomaxillofacial surgery. Traditionally, patient-specific data is gathered by conventional computed tomography (CT). However, cone-beam CT (CBCT) can generate a 3D reconstruction of the area of interest with a lower dose of radiation at reduced cost.

Current concepts in cleft care: A multicenter analysis.

The current surgical techniques used in cleft repair are well established, but different centers use different approaches. To determine the best treatment for patients, a multi-center comparative study is required. In this study, we surveyed all craniofacial departments registered with the German Society of Maxillofacial Surgery to determine which cleft repair techniques are currently in use.

The localization and risk factors of squamous cell carcinoma in the oral cavity: A retrospective study of 1501 cases.

Head and neck cancer is the tenth leading cause of cancer mortality. Ninety percent of tumours in the oral cavity are squamous cell carcinomas. Information about the exact localisation of OSCC is missing in the literature.

Optical sensor system for time-resolved quantification of methane densities in CH-fueled spark ignition engines.

We present the development and the first application of an optical sensor system that allows single-cycle determination of methane (CH) concentration inside internal combustion (IC) engines. We use non-dispersive infrared absorption spectroscopy to detect the CH density with a time resolution up to 33 μs at acquisition rates of 30 kHz. The measurement scheme takes advantage of the strong temperature dependence of the absorption band applying two detection channels for CH that detect different spectral regions of the ν anti-symmetric C-H-stretch absorption.

Previous malignancy is an independent predictor of follow-up mortality after percutaneous treatment of mitral valve regurgitation by means of MitraClip.

Aims: To investigate the prognostic burden of previously diagnosed and treated malignancies in candidates for percutaneous mitral valve repair (MVR) with MitraClip.

Methods And Results: A total of 165 patients underwent MVR and 19 (11.5%) had been previously treated for malignancy and considered healed with life expectancy over 1 year at time of percutaneous MVR.

MitraClip step by step; how to simplify the procedure.

The MitraClip system is a device for percutaneous edge-to-edge reconstruction of the mitral valve in patients with severe mitral regurgitation who are deemed at high risk for surgery. Studies have underlined the therapeutic benefit of the MitraClip system for patients at extreme and high risk for mitral valve surgery, suffering from either degenerative or functional mitral regurgitation. The MitraClip procedure shows low peri-procedural complication rates, and a significant reduction in mitral regurgitation, as well as an improvement in functional capacity and most importantly quality of life.

Moving the mandible in orthognathic surgery - A multicenter analysis.

Orthognathic surgery has always been a classical focus of maxillofacial surgery. Since more than 100 years, various surgical techniques for mandibular repositioning have been developed and clinically tested. Since the establishment of plate and screw osteosynthesis, orthognathic surgery became more stable and safe.

Occurrence of cervical lymph node metastasis of maxillary squamous cell carcinoma - A monocentric study of 171 patients.

Introduction: Fewer than 5% of oral squamous cell carcinomas (SCC) are presented in the maxilla. The absence of cervical lymph node metastasis (LNM) is one of the main positive prognostic factors. This single-centre study analysed the cervical lymph node metastasis behaviour in patients with oral SCC of the upper jaw and serves as a basis for a cervical lymph node treatment suggestion.

Expression of ezrin in oral squamous cell carcinoma: Prognostic impact and clinicopathological correlations.

Introduction: There have been few investigations into the effects of ezrin expression in oral squamous cell carcinoma (OSCC). The aim of this study was to analyze the influence of ezrin expression on the prognosis of patients with OSCC.

Materials And Methods: Eighty patients were included in the retrospective study.

The current state of facial prosthetics – A multicenter analysis.

Even though modern surgical techniques are dominating reconstructive facial procedures, the capability to use facial epitheses for reconstruction is still an important skill for the maxillofacial surgeon. We present an international multicenter analysis to clarify which techniques are used to fixate facial prostheses. We contacted all maxillofacial departments in Germany, Austria, Switzerland and Norway which were registered with the German society for oral and maxillofacial surgery (DGMKG).

Indications for the microvascular medial femoral condylar flap in craniomaxillofacial surgery.

The medial femoral condylar flap makes it possible to reconstruct bone, cartilage, and skin, but elongation of the pedicle is usually required to bridge the distances to the vascular connections in the neck. The indications in the maxillofacial area include reconstruction of the temporomandibular joint (TMJ), pseudarthrosis of the jaws, osteonecrosis of the jaws and skull, and augmentation of bone in irradiated or otherwise compromised tissue. If small bony defects require safe and reliable osseous, osteochondral, or osteocutaneous reconstruction, the medial femoral condylar flap can be used to fill the gap between small avascular, and larger microvascular, bone transplants.

Facial basal cell carcinoma with successive metastases to the neck, thyroid gland and lung.

Basal cell carcinoma of the skin is the most common malignancy in the head and neck area. Regional and distant metastases rarely occur with this type of tumour. We report an uncommon case of a sclerodermiform basal cell carcinoma of the facial skin in which metastases developed several years after the primary tumour.
