INTRODUCTION: Ultrasonography is the easiest non-invasive method to diagnose lymph node metastases in patients with head and neck cancer. However, since CT scans are often preferred in the evaluation of primary tumours of these patients, information about lymphatic metastases may also available in these patients. Therefore, ultrasound is not routinely employed in the evaluation of these patients. However, elastography technique, a recent development in ultrasound technology, could make use of ultrasonography in these patients even more widespread, even though it is still not widely used today...

Precision medicine is increasingly pushed forward, also with respect to upcoming new targeted therapies. Individual characterization of diseases on the basis of biomarkers is a prerequisite for this development. So far, biomarkers are characterized clinically, histologically or on a molecular level. The implementation of broad screening methods ("Omics") and the analysis of big data - in addition to single markers - allow to define biomarker signatures. Next to "Genomics", "Proteomics", and "Metabolicis", "Radiomics" gained increasing interest during the last years...

INTRODUCTION: Sinonasal inflammatory conditions account for a major component of head and neck pathologies, whereas neoplasms involving the sinonasal region make up only 2-3% of all head and neck lesions. The symptoms of sinonasal tumors are nonspecific; imaging plays a critical role in distinguishing benign and malignant disease and may illustrate characteristic radiological features of specific sinonasal tumors. OBJECTIVE: Aim was to determine the utilization of multimodality imaging, specifically the metabolic information provided by 18-fluorodeoxyglucose positron emission tomography (18 F-FDG PET/CT) and diffusivity characteristics seen with diffusion weighted images (DWI) of magnetic resonance imaging (MRI), in a wide range of benign and malignant sinonasal tumors drawn from over 200 sinonasal lesions from our institution and supplemented by the literature...

Introduction: The Union for International Cancer Control-American Joint Committee on Cancer TNM staging system for glottic squamous cell carcinoma (SCC) includes different types of lesions defined by the involvement of specific subsites in each T category. Our study aims to identify different subcategories according to tumor local extension and determine oncologic outcomes after treatment by transoral laser microsurgery (TLM) alone. Methods: We retrospectively evaluated 410 patients affected by previously untreated pT1-pT3 glottic SCC treated by TLM alone from January 2005 to December 2015 at the Departments of Otorhinolaryngology-Head and Neck Surgery, Universities of Genoa and Brescia, Italy...

Epidermoid cysts are benign lesions, which are usually detected on the floor of the mouth in the head and neck region. They can develop from abnormal epithelial components of an ectoderm tissue during the embryological life or alternatively they can arise from the implanted epithelium after trauma or surgery. The diagnosis of an epidermoid cyst in the maxillary sinus can be challenging and it could be easily mistaken for any benign or malign lesion of the nasal cavity and paranasal sinuses. In this case, we present a 44-year-old man with a giant epidermoid cyst in the right maxillary sinus with a previous history of paranasal sinus surgery...

BACKGROUND: When treatment of acute septic arthritis of the hip is delayed, severe sequelae can occur. This may take the form of coxa breva, vara, or valga. Pseudoarthrosis of the femoral neck is a rare complication with only a few studies to guide treatment. QUESTION/PURPOSES: In a small series of patients with pseudarthrosis of the femoral neck after acute septic arthritis, we wanted to determine (1) whether femoral neck union can be achieved using a variety of surgical approaches; (2) whether these patients satisfied criteria outlined by Hunka and Choi, defined as a stable hip, a flexion arc ≥ 70° and no fixed adduction or abduction contractures, fixed flexion deformity not more than 20°, pain relief, and restoration of activities of daily living after surgery; and (3) any treatment-related complications if observed...
