During endoscopic sinus surgery, the sinus drill was inserted into the patient´s right sinus and visible on the screen.Upon activating the foot pedal, the tip of drill #1 broke off in the patient´s sinus.The surgeon retrieved the broken piece and reported seeing no missing pieces left in the sinus.Inspection of the drill bit indicated coiled sheath that spirals around the inner piece seemed to have twisted off.An x-ray was performed to ensure there were no parts left in the patient´s sinus.Opened a second drill bit (#2).This piece showed the drill was about to break apart as well and it was removed from the field in one piece.Opened a third drill bit (#3).This drill would not fit into the drill handpiece.In addition, the hydrodebrider handpiece was manufactured wrong; it was missing a piece to be able fit into the machine/equipment.Additional supplies were used when the burr became loose (drill #4 and drill #5).
