Intraoperative accidental extubation of the endotracheal tube during surgery, especially in the prone position, is one of the most critical perioperative complications. In this report, we introduce the “ear-hooking method” of the endotracheal tube to avoid accidental extubation during surgery. We have used this method for more than 10 years in approximately 200 patients with multiple injuries who required posterior cervical supine surgery. For the ear-hooking method, two crafted elastic adhesive tapes fix the intubation tube to the head;one to the upper jaw and the other to the lower jaw. By correctly performing this tube-fixation method, we reduced the risk of fatal intraoperative accidental extubation.
