Abstract:

Objective    To discuss the methodology and advantage of endoscopic sinus surgery on cyst of the nasal sinus with an image navigation system. Methods    121 patients with cyst of the nasal sinus underwent the operation. Among them, 12 were diagnosed as maxillary sinus mucinous cyst, 5 maxillary mucosal antral sinus, 43 ethmoid mucinous cyst, 29 mucocele of the frontal sinus，and 32 mucocele of the sphenoid sinus. All surgical procedures were done with general anesthesia, and pinpoint positioning was done using a navigation system. The probe or suction unit was calibrated when needed, and the cyst was partly or fully removed by the shortest path with the help of an endoscope and a navigation system. Results    All the operations were done with minimal trauma and no complications occurred. Conclusions    A navigation system in combination with a sinus endoscope is helpful in locating a cyst of the nasal sinus with minimal trauma, increasing the curative effect and avoiding complications.
