全身麻醉後吞入固定假牙之病例報告

牙齒損傷是插管全身麻醉中常見的併發症。在日本的一項統計資料裏，氣管插管所造成的牙齒損傷約有0.69%的機會，而根據國內在1990年報告的資料，在麻醉前、中、後均請牙醫師診視時，發現牙齒損傷的機會高達12.1%斷裂或脫落的牙齒或假牙可造成嚴重，甚至於致死的併發症。在這裏我們報告一個在全身麻醉後固定式假牙吞入腹中的病例，提供各位麻醉下接受右耳的改良性根除中耳炎合併聽力失聰，患者於插管全身麻醉下接受右耳的改良性根除性乳突切除術。他上顎的固定式假牙可能是在插管的過程中導致鬆動，但是因為外觀看似正常所以當時並未被發現。而在手術結束，患者於麻醉恢復室中意識尚未完全清楚之時，假牙被吞入腹中，經X光檢查而確定診斷。所幸在密切追蹤下，發現假牙於術後30小時在解便時自然排出，沒大造成其它的併發症。

Dental injury is a common complication associated with endotracheal general anesthesia. According to a study in Japan, the incidence of dental injury caused by endotracheal intubation is 0.69%. In one study in our country, evaluation of the oral condition was performed before, during and after anesthesia, and the frequency of dental trauma is as high as 12.1%. Fragment(s) of tooth or denture may cause serious, or even fatal complications. We report a case of swallowing of fixed denture following endotracheal general anesthesia. Our accident involved a 33-yr-old male who had experienced bilateral auditory impairment as a result of chronic otitis media. The patient underwent right modified radical mastoidectomy under endotracheal general anesthesia. It might well be that the patient's maxillary fixed denture was loosened at the time of endotracheal intubation. However, patient's denture was normal in appearance and not much attention was paid to it. During his stay at the post-anesthesia care unit, he might have unconsciously swallowed his denture. Verification was later made by X-ray. On careful observation, his denture was found in the feces during defecation 30 h post-operatively.
