We report a rare case of accident entry of titanium screw into the sphenoid sinus during paranasal augmentation with porous polyethylene implant. The screw was finally retrieved from the sphenoid sinus by a nasal endoscope. We emphasize that, on this surgery region, the simple fixation skill must be performed delicately. Otherwise, an adverse event may still happen.
