Image-guided functional endoscopic sinus surgery

摘要: Abstract Introduction: Computer-aided surgery (CAS) technology in functional endoscopic sinus (FESS) has engendered considerable discussion. Objective: The goals of this study were to describe CAS preoperative planning (software-based CT image analysis) and develop intraoperative strategies for surgery. Study Design: Between October 1, 1997, December 31, 1998, the StealthStation (Sofamor Danek, Memphis, TN) was used 61 FESS cases, a retrospective review findings performed. indication all instances chronic rhinosinusitis refractory medical management. scans before Anatomic fiducial registration supplemented by contour mapping used. Results: Localization accuracy estimated be within 2 mm or better. both localization. useful frontal recess, sphenoethmoid region, posterior ethmoid system, skull base area. deemed helpful situations where surgical anatomy altered previous extensive inflammatory disease (polyposis, fungal sinusitis, pansinusitis). Conclusion: paradigm image-guided surgery, which integrates into FESS, will serve increase effectiveness decrease morbidity. (Otolaryngol Head Neck Surg 2000;123:188–94.)
