Evaluation of imaging navigation system during endoscopic sinus surgury / 中国耳鼻咽喉头颈外科

ABSTRACT

OBJECTIVE Evaluation of imaging navigation system during endoscopic sinus surgury and compared endoscopic sinus surgery with and without image guidance, analyzing a number of parameters that can impact on efficacy. METHODS Retrospective review of 76 imaging-navigated endoscopic sinus surgery with image-guidance systems at our department between Jan 2000 and May 2003, including 20 consecutive pituitary adenoma patients and 10 nasal-sinus ossifying fibroma. The control group consisted of 10 nasal-sinus ossifying fibroma patients between Jan 1997 and May 2003 and 20 consecutive pituitary adenoma patients between Jan 1999 and May 2003 who underwent ESS without image guidance. The main outcomes measured were analysis of the using times of different diseases, the user's satisfication in different diseases, and compared pituitary adenoma/ossifying fibroma ESS with and without image guidance. RESULTS The using times of different diseases are different, the user feel satisfication in all cases but the degree is different with diseases. The patient's characterisitics of the two groups of pituitary adenoma/ossifying fibroma were similar in age and gendle. There are no statistically significant differences in estimated blood loss, operative time, anesthesia time. CONCLUSION Imaging navigation systems in different nasal-sinus diseases are all useful. Our experience illustrates the importance of the learning curve, we believe that the problems we had with those systems were largely operator-dependent and that these can be overcome with proper experience and training. For small group patients, it's no evidence to show in ESS can make more complete resection of nasal-sinus ossifying fibroma, but has evidence to show no more cost.
