AbstractDental guards are an airway adjunct recommended for patients at risk for dental injury during airway instrumentation; however, reportedly only 2% of anesthesiologists use dental guards during intubation. In this case report, a 64-year-old patient was admitted for a right retromastoid craniectomy with microvascular decompression of the fifth cranial nerve. The patient had crowns on all her maxillary teeth. The anesthesia team, which consisted of a student anesthetist, Certified Registered Nurse Anesthetist, and anesthesiologist, planned to prevent dental damage through the use of a dental guard (Bay Medical, Clearwater, Fla). Prior to intubation a dental guard was inserted on the upper teeth. Induction, intubation, and surgery were uneventful, but in the recovery area the patient complained of a sore throat. After transfer to the intensive care unit, the patient continued to complain of secretions and sore throat and was noted to have hoarseness. When a Yankauer suction catheter was inserted, the dental guard was discovered in the patient's mouth. Apparently during the busy sequence of events following intubation, the dental guard was overlooked and was displaced into the posterior oropharynx. Recommendations for the proper use of dental guards are needed to avoid complications; however, there is a scarcity of information available in the conventional anesthesia literature regarding this intubation adjunct. We recommend careful documentation, clear communication with all team members, and attention to avoid displacement during subsequent airway manipulation.
