BACKGROUND The objective was to evaluate the diagnostic accuracy of ultrasmall superparamagnetic iron oxide (USPIO)-enhanced magnetic resonance imaging (MRI) compared to plain MRI in patients with a clinical N+ neck using histology as a gold standard. MATERIALS AND METHODS Twenty-eight patients underwent unenhanced and USPIO-enhanced MRI using T1-weighted(More)
AIM To evaluate the accuracy of ultrasmall paramagnetic iron oxide (USPIO: Sinerem)-enhanced MRI in patients with head and neck cancer and enlarged lymph nodes compared with current staging examinations using histology as a gold standard. PATIENTS AND METHODS Seventeen patients with a histologically proven squamous cell cancer of the head and neck (SCCHN)(More)
Distraction osteogenesis has become a popular treatment of congenital maxillocraniofacial anomalies. Many ingenious internal and external devices have been developed and used. The rigid external distraction system based on systems previously used in correction of maxillary retrusion offers postoperative adjustment in two dimensions. Figueroa and Polley(More)
PURPOSE Piezo-osteotomy feasibility as a substitute for the conventional saw in orthognathic surgery was evaluated regarding operative technique, blood loss, time requirement, and nerve and vessel integrity. PATIENTS AND METHODS Fifty patients had orthognathic surgery procedures in typical distribution using piezosurgical osteotomy: 22 (44%) monosegment,(More)
This report documents successful tooth autotransplantation to a free iliac crest graft in an exemplar case. A 14-year-old male patient was operated thrice with increasing amounts of resection for recurrent odontogenic myxoma. When mandibular continuity resection finally was performed, a free iliac crest block autotransplant was used for reconstruction. Upon(More)
The lymph node staging is a very important prognostic parameter for patients with presenting with head neck cancer and is influencing the selection of the different therapeutic strategies including surgery, chemotherapy, radiotherapy or a combination of them. The accuracy of imaging techniques, such as US, MR imaging, and CT, depends on the appropriateness(More)
OBJECTIVE The objective of this study was to evaluate piezoosteotomy for bone harvesting at the iliac crest in a pilot collective. STUDY DESIGN Thirteen patients underwent anterior iliac crest bone graft harvesting using piezoosteotomy. These patients were compared to an age- and sex-matched retrospective cohort of 13 patients who underwent bone graft(More)
Cervical spine involvement is a common feature in the course of long existing rheumatoid arthritis (RA).We describe a rare type of vertical subluxation with pronounced cranioventral disposition of the odontoid process and neo(pseudo)arthrosis between the skull and the tip of the odontoid processus. This 74-year-old women with RA for 40 years had progressive(More)
In this observer-blinded, multicenter, non-inferiority study, 489 patients suffering from painful osteoarthritis of the hip or knee were included to investigate safety and tolerability of Dexibuprofen vs. Ibuprofen powder for oral suspension. Only patients who had everyday joint pain for the past 3 months and “moderate” to “severe” global pain intensity in(More)
