A Case of Endotracheal Tube Damage during Maxillo—Mandibular Osteotomy

We experienced a case in which the endotracheal tube was damaged during maxillo-mandibular osteotomy. The patient was a 16-year-old male with an oblique facial cleft. After induction of general anesthesia, the trachea was intubated nasotracheally for airway management. During the maxillo-osteotomy, the surgeon noticed that he had accidentally damaged the endotracheal tube with the bone chisel. Since severe bleeding and edema were observed in the operative field, we thought that it would be dangerous to exchange the endotracheal tube at that time, but we decided that the surgery could be continued because the level of mechanical ventilation was acceptable. After surgery, a small crack of 7 mm was found in the endotracheal tube using bronchial fiberscopy. After repair of the endotracheal tube by wrapping the crack with tape, the patient was transferred to the intensive care unit.
