BACKGROUND With the decrease of life-threatening obstructive upper airway infections and the ongoing improvement of intensive care medicine, the role of tracheostomy in children has been changing considerably, until now. The aim of this study was to establish data regarding indications, complications, and techniques of pediatric tracheostomy, which would(More)
CAS — computer assisted surgery — is a new imaging method supporting skull base surgeons. Support is granted not only for preoperative planning of therapy but also for pathfinding during surgery itself and in the postoperative phase as therapy control. TheCAS-system consists of high technology items such as -a digital image generation system (CT, MR) -a(More)
OBJECTIVE To develop strategies that may assist the surgeon to prevent and manage severe bleeding complications after adenoidectomy and tonsillectomy. STUDY DESIGN Retrospective. SUBJECTS AND METHODS Expert reports for malpractice lawsuits or professional boards were reviewed. The review was restricted to "deaths" and "permanent generalized neurological(More)
Despite the large number of tonsillectomies performed little knowledge exists about post-tonsillectomy hemorrhage (PTH) with lethal outcome. This study was performed to evaluate clinical features in a larger patient population with emphasis on the onset of this complication. A nationwide collection of cases was performed based on personal communication,(More)
Computer-assisted surgery (CAS), a new navigation aid for skull-base surgery, is discussed. The system described combines 3-D coordinate measurement techniques, voxel processing methods, and pseudo-3-D image presentations to support preoperative planning of therapy, path-finding during the operation itself, and postoperative therapy control. The surgeon(More)
OBJECTIVES/HYPOTHESIS In rare cases, the intensity of posttonsillectomy hemorrhage (PTH) may become life-threatening requiring major surgical means and intensive care. This study was conducted to assess the outcome of life-threatening PTH and its clinical features in a larger patient population. STUDY DESIGN AND METHODS Cases occurring during the clinical(More)
Available data about the size of the different sinuses to date are derived from anatomical or radiological studies. In order to verify or possibly correct the findings of other authors we evaluated the cranial computed tomography (CT)-images of more than 5600 patients. We measured the sex-linked and age-dependent width and length of the four sinuses for(More)
BACKGROUND Serious post-tonsillectomy hemorrhage (PTH) is an uncommon complication requiring immediate and adequate medical treatment. This study was undertaken to describe and evaluate the clinical data and courses of serious PTH, with and without lethal outcome in children and adolescents. MATERIALS AND METHODS Bleeding episodes accompanied by(More)
Computer assisted surgery (CAS) is a new imaging technique designed to assist the head and neck surgeon during surgery. This method is based upon a three-dimensional volume model of the patient's skull generated by computer tomographic imaging procedures such as CT and MR. Body points can be marked in the 3-D model by intra-operative correlation of model(More)
