Description

We performed endoscopic re-operation on a patient with a relapsed cyst of the right sphenoidal sinus under X-ray imaging. The case was a 59-year-old man complaining of double vision due to a right sphenoidal cyst, and cysts of the bilateral sphenoidal sinus had been operated on at 52 years old. Because of postoperative stenosis of the right nasal cavity, we endoscopically opened the right sphenoidal cyst through the left sphenoidal sinus. In order to avoid skull base injury, endoscopic opening of the cyst wall was performed securely under X-ray imaging. X-ray imaging is a useful tool supporting endoscopic sinus surgery, as an alternative to the navigation system.<br>
