Tooth aspiration in two cats following maxillofacial trauma

CASE SERIES SUMMARY: Tooth aspiration is a rare occurrence in human medicine, and even more so in veterinary medicine. This report describes two cats that aspirated a tooth (one canine tooth and one premolar tooth) following maxillofacial trauma. One cat presented with dyspnoea, while the other showed no respiratory clinical signs. In both cases diagnosis was reached by obtaining routine thoracic radiographs, and successful retrieval of the teeth was achieved by bronchoscopy. Both cats recovered uneventfully. RELEVANCE AND NOVEL INFORMATION: To our knowledge, this is the first report in the veterinary literature of tooth aspiration into the tracheobronchial tree following maxillofacial trauma. The scope of this case series is to raise awareness that tooth aspiration can occur following maxillofacial trauma and has the potential for serious complications if not diagnosed and treated promptly. Therefore, an oral examination must be performed in every maxillofacial trauma patient and missing teeth should be accounted for, even when respiratory clinical signs are not detected.
