Event Description

Medtronic received information regarding a navigation system being used for a functional endoscopic sinus surgical procedure.It was reported that after performing a registration with the system, the surgeon believed it to be 3 mm inaccurate (inferior and deep to the face).This was with both the registration probe and with the sinus shaver.Technical services had the surgeon try the following: re-registering and focusing on collecting points across the bridge of the nose and only tracing on bony anatomy; switching to 3-point touch; switching to patient reference frame; and adding touch points.After switching to the patient reference registration type and adding two touch points, the entire scan was encompassed by the green circle and a registration metric of 1.4 was achieved.The surgeon said it was more accurate but still was about 1 mm off.This occurred intraoperatively, and there was a surgical delay of less than one hour.There was no impact to patient outcome.
