Some modern neuronavigation systems are able to register any surgical instrument and create a virtual pointer. A virtual elongation of the digitized instrument is frequently used for neuroendoscopic procedures and spinal instrumentation. The instrument is equipped with a universal instrument adapter clamp and digitized by touching the tip of the instrument into a calibration cone. An algorithm calculates the vector of the instrument using two points: the tip of the instrument, and the geometrical center of the instrument adapter geometry. If a virtual elongation of the calibrated instrument is performed, the neuronavigation software may calculate an incorrect virtual target point. We developed an instrument calibration matrix (ICM) that automatically calibrates the correct vector, tip, and diameter of the instrument used for image-guided surgery. The ICM is easy to handle and does not cause a time delay during surgery. Virtual elongation of the surgical instruments shows correct anatomic data, which are fundamental for planning ventricular tapping and spinal screw placement in particular. The instrument calibration matrix is essential if surgical instruments are digitized and used for neuronavigation. It helps to avoid mis-planning of surgical vectors and mis-placement of the used instruments.","PeriodicalId":49808,"journal":{"name":"Minimally Invasive Neurosurgery","volume":"11 1","pages":"88 - 91"},"PeriodicalIF":0.0,"publicationDate":"2001-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91070762","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Nevertheless, these rare tumours of the frontal skull base are still associated with high rates of tumour recurrence and mortality, thus remaining a challenge even for experienced surgeons. A novel therapeutic approach that combines endoscopic sinus surgery and radiosurgery (gamma knife) is presented here. Six patients (3 males, 3 females) aged between 27 and 75 years (median 38 years) were treated between August 1993 and July 1999. Following paranasal and nasal endoscopic sinus surgery, marginal irradiation doses ranging from 16 to 34 Gy were applied radiosurgically involving up to 7 isocentres. At present, the median follow-up period is 57 months (range: 9 - 79 months). Without mortality, tumour control was achieved in all patients. One patient, who had to undergo additional craniotomy because of extensive neoplastic infiltration, developed postoperative liquorrhea. In another case the clinical course was complicated by a bilateral frontal sinusitis. All patients complained of nasal discharge and crusts. However, a preoperative Karnovsky Index ranging from 80 to 100 % remained stable in four patients whereas an improvement was observed in two patients. Based on the favourable results observed so far, the combination of endoscopic sinus surgery and radiosurgery can be considered as promising new option for the treatment of esthesioneuroblastoma that merits further investigation.","PeriodicalId":49808,"journal":{"name":"Minimally Invasive Neurosurgery","volume":"50 1","pages":"79 - 84"},"PeriodicalIF":0.0,"publicationDate":"2001-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77143541","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
