Evaluation of Mandibular Fractures in a German Nationwide Trauma Center Between 2015 and 2017.

Introduction: This study analyses the treatment of isolated mandibular fractures between 1.1.2015 and 21.

Evaluation of Panfacial Fractures in a German Supraregional Trauma Center between 2015 and 2017 - A Retrospective Study.

Introduction: Panfacial fractures represent the most severe injuries to the face. The combination of these fractures determines the treatment strategy. This study aims to retrospectively review the data of adult patients treated for complex facial skull fractures in a hospital in Dortmund, Germany from 2015-2017.

Long-term evaluation of treatment protocols for isolated midfacial fractures in a German nation-wide craniomaxillofacial trauma center 2007-2017.

An update on the trends in maxillofacial traumatology provides additional information on the actual and changing needs. This retrospective study aimed to review all patient records of patients treated for isolated midface fractures in the Department of Cranial- and Maxillofacial Surgery at the Dortmund General Hospital between 2007 and 2017. The patient radiographs and patient files were reviewed.

Fracture heat map of the facial skull demonstrates a danger zone of concomitant cervical spine injuries.

Concomitant maxillofacial and cervical spine injuries occur in 0.8-12% of the cases. We examined the relation of injury localization and the probability of cervical spine fracture.

A randomized, prospective trial to assess the safety and efficacy of hilotherapy in patients after orthognathic surgery.

Purpose: A post-operative cooling method in oral and maxillofacial surgery is the cooling with hilotherapy. The aim of this study was the post-operative comparison of cooling temperatures of 18°C and 22°C. The parameters of this trial were swelling and the post-operative pain levels.

Complications after osteosynthesis of craniofacial fractures-an analysis from the years 2015-2017.

Background: Complications mean a recurring problem in everyday clinical practice. Complication rates between 6 and 13% are described for the treatment of bony injuries to the head and neck area. This paper aims to provide a detailed analysis of the complications after osteosynthesis in facial skull fractures.

Application of patient-specific simulation workflow for obstructive sleep apnea diagnosis and treatment with a mandibular advancement device.

A computational fluid dynamics simulation workflow was developed to analyze the upper airway of patients with obstructive sleep apnea, which is a potentially serious sleep-related breathing disorder. A single characteristic parameter was introduced to assess the severity of sleep apnea on the basis of the numerical results. Additionally, a fluid-structure interaction simulation was applied to study in detail the behavior of compliant pharyngeal walls.

Hidden danger in the neck-a problem of differential diagnostics: benign chronic lymphadenitis following carotid endarterectomy and patch angioplasty (CEAP) or a metastasis due to a squamous cell cancer of the tongue.

Introduction: Oncological head and neck operations as well as carotid endarterectomy are common surgical procedures. In some occasions, both procedures have occurred in the past, leading to possible diagnostic and therapeutic challenges when follow-up operations seem indicated.

Case Report: We report of a patient presenting with carotid endarterectomy including patch operation 8 years ago and neck dissection due to a squamous cell cancer of the tongue 3 months ago, now showing up with a suspected metastatic tumor of the neck during routine follow-up.

Sudden death after major head and neck cancer surgery due to undetected arrhythmogenic right ventricle cardiomyopathy (ARVC).

Background: Oral squamous cell carcinoma is the sixth most frequent malignancy in Austria. The incidence of arrhythmogenic right ventricle dysplasia (ARVC), an important cause of sudden cardiac death, is estimated at 1:5000 to 1:1000.

Case Report: We present a case of a 75-year-old woman who underwent major oncologic surgery for T4aN0M0 maxillary squamous cell carcinoma and reconstruction with a scapular-latissimus dorsi microvascular flap.
