    Abstract:
    OBJECTIVE: To evaluate the applicative value of computer assisted navigation system in endoscopic sinus and skull base surgery. METHOD: Forty-nine endoscopic surgery procedures were performed with the help of computer assisted navigation system, among which there were 25 cases of recurrent sinusitis and nasal polyps, 9 cases of nasal and sinus tumour, 7 cases of cerebrospinal fluid rhinorrhea, 2 cases of meningoencephalocele, 4 cases of congenital choanal atresia, 1 case of pituitary tumor and 1 case of foreign body in middle cranial fossa. RESULT: The preoperative time was 5-13 minutes for preparation, 7 minutes in average. The target error was less than or equal to 1.5 mm. All the 49 cases had successful surgery without complications. CONCLUSION: Computer assisted navigation system can help the surgeon to determine the sinus, skull base and adjacent anatomic landmarks correctly, improve surgical accuracy and safety, and reduce intraoperative and postoperative complications.
