A 74-year-old man was transported by emergency services due to head and neck trauma. He had obvious facial soft-tissue injuries, and teeth were broken. Because the patient had oral bleeding, we intubated the patient for airway management with a tracheal tube. The patient was diagnosed with a right Le Fort type II fracture, a left Le Fort type III fracture, and a cervical vertebral fracture at C2 and subarachnoid hemorrhage and was admitted to our hospital. The patient was fixed with a neck collar and ventilated. Two days after admission, chest computed tomography revealed a calcified foreign body with a short diameter of 8.0 mm in the right lower lobe bronchus with distal lung consolidation [Figure 1]a, [Figure 1]b, [Figure 1]c. The patient had no fever and no respiratory failure. Bronchoscopy through a tracheal tube showed that a broken tooth was present at the entrance to the right lower bronchus [Figure 2]a. However, the size of the object was too large to remove through the tracheal tube. Because the patient needed ventilator management for the treatment of facial fractures, a tracheostomy was scheduled. After the tracheostomy under general anesthesia, it was decided to remove the broken tooth with a flexible bronchoscope (OLYMPUS BF-260, Olympus, Tokyo, Japan). A tracheostomy tube was inserted, and bronchoscopy was performed through the tube. The forceps, a wire basket and a Fogarty balloon catheter could not remove. The tooth was scraped out with a curette [Figure 2]b, and it was removed using a retrieval net (OLYMPUS 00711191) [Figure 2]c. There was no granulation or bleeding at the right lower bronchus after removal of the broken tooth [Figure 2]d.

There are various risk factors for foreign body aspiration. If a long period from aspiration passes, granulation tissue forms easily. Furthermore, because the lining mucosa may be traumatized, or airway obstruction, atelectasis, bronchiectasis, obstructive pneumonia, or lung abscess may occur, it is important to diagnose foreign body aspiration quickly and remove the object immediately.[1] In the present case, it took 7 days to remove the airway foreign body, and there was no granulation. For the treatment of airway foreign bodies, removal with a flexible bronchoscope is the first choice. A curette, forceps, wire basket, a Fogarty balloon catheter, and a retrieval net are frequently used to remove such objects. In this case, the tooth could not be removed with grasping forceps, a wire basket, and a Fogarty balloon catheter. A curette was used to scrape out the tooth, and it could be removed with a retrieval net. A retrieval net is used for large objects and those that are difficult to trap with a wire basket, and a curette is used to assist them.[2],[3] In some cases, a foreign body is too large to remove through a tracheal tube.[4] Kim et al. reported a method of removing an object after tracheostomy.[5] However, in the present case, general anesthesia was necessary to perform a tracheostomy safely, because the patient had difficulty with neck extension. Furthermore, it was necessary to remove the foreign body after tracheostomy, because the object was too large to pass through the tracheal tube. Because of the above reasons, it was decided to remove it using a flexible bronchoscope under general anesthesia. Although there are not many patients with airway foreign bodies, it is important to consider an excision method and the timing based on each patient's clinical condition. To the best of our knowledge, there have been few reports of removal of an aspirated broken tooth using a curette and a retrieval net after tracheostomy in a patient with tracheal intubation after trauma. One can assume that the present case is extremely rare, but an airway foreign body should not be overlooked, because it requires appropriate treatment.

   Conclusion Top

A case in which a broken tooth was aspirated after head and neck trauma, and it was removed using a flexible bronchoscope after tracheostomy was presented. In trauma patients, we should consider the possibility of the presence of airway foreign bodies. Although a flexible bronchoscope is useful for removing objects in the lower bronchus, it is important to select an appropriate removal method and timing according to the type and size of the foreign body and the general condition of the patient.
