Abstract:
Objective To evaluate the clinical application of computer-aided electromagnetic imaging navigation in nasal endoscopic surgery.Methods Twenty-two cases of nasal endoscopic surgery with intraoperative imaging navigation were retrospectively reviewed,including 16 cases of sinusitis with or without polyp;5 cases of nasal inverting papilloma; 1 case of maxillary capillary hemangioma.All cases were operated with computer-aided electromagentic imaging navigation and nasal endoscope.Results The preoperative preparing time would take 4-10 minutes.In 22 cases,the localization accuracy between 3-D image landmarks of navigation system and actual anatomical landmarks was less than 1 mm.The optic nerve and other anatomical landmarks could be orientated accurately in intraoperative procedures.No complication occurred.Conclusions Nasal endoscope combined with computer-aided electromagnetic imaging navigation provides accurate anatomical localization of nasal cavity,sinuses and anterior skull base.It could improve the effectiveness and decrease surgical complications,especially in complicated cases.
