BACKGROUND The aim of this work was to determine the feasibility of a robotic-assisted and fully automated approach to the sphenoid sinus. An image-guided robotic system was designed to address potential human errors in performing transsphenoidal sinus surgery by combining the reproducible accuracy of a robotic system with standard computer navigation.

We present an advanced version of our robotic setup for paranasal sinus surgery that was developed at the Department of Otorhinolaryngology, Head and Neck Surgery in Erlangen, Germany. The system was interconnected with a redundant navigation system for increasing intraoperative safety while performing telemanipulatory as well as fully automated(More)
Clinical GeneOrganizer (CGO) is a novel windows-based archiving, organization and data mining software for the integration of gene expression profiling in clinical medicine. The program implements various user-friendly tools and extracts data for further statistical analysis. This software was written for Affymetrix GeneChip *.txt files, but can also be(More)
A 77-year-old man suffered hypoxemic cardiac arrest by supraglottic and tracheal airway obstruction in the emergency department. A previously unknown cervical fracture had caused a traumatic retropharyngeal-mediastinal hematoma. A lifesaving surgical emergency tracheostomy succeeded. Supraglottic and tracheal obstruction by a retropharyngeal-mediastinal(More)
INTRODUCTION We wish to report on a rare cause of dysphagia; oculopharyngeal muscular dystrophy (OPMD). It is a late adult onset autosomal dominant form of muscular dystrophy that constitutes as a rare diagnosis for any place outside of Canada and first case in southern Germany. CASE PRESENTATION We report the medical odyssey of a 57-year old male(More)
A 47-year old man presented with a five-year history of fluctuating hearing impairment in the left ear. There was no tinnitus or vertigo. Imaging studies demonstrated a contrast-enhancing cerebellopontine angle mass in the left internal auditory canal. Surgically the lesion was attached to the cochlear nerve. Pathological evaluation revealed what is best(More)
BACKGROUND Recent studies demonstrate that recombinant adeno-associated virus (rAAV)-based antigen loading of dendritic cells (DCs) generates in vitro, significant and rapid cytotoxic T-lymphocyte (CTL) responses against viral antigens. METHODS We used the rAAV system to induce specific CTLs against CVM antigens for the development of cytomegalovirus(More)
OBJECTIVE To introduce a new robotic system to the field of neurosurgery and report on a preliminary assessment of accuracy as well as on envisioned application concepts. Based on experience with another system (Evolution 1, URS Inc., Schwerin, Germany), technical advancements are discussed. MATERIAL/METHODS The basic module is an industrial 6 degrees of(More)
When it comes to restoring impaired neural function by means of surgical reconstruction, sensory nerves have always been in the role of the neglected child when compared with motor nerves. Especially in the head and neck area, with its either sensory, motor or mixed cranial nerves, an impaired sensory function can cause severe medical conditions. When(More)
