摘要

顱顏創傷後造成嗅覺失能的發生率約爲4至7%，此類嗅覺失能通常無法自行復原，且仍無標準之治療方式。本病例報告爲一24歲男性，因機車車禍導致顏面創傷而喪失嗅覺，未接受特殊治療而自行恢復之過程。意外當時病患無頭部外傷，僅顎顏面區骨折，於本院接受常規之手術治療，術後發現嗅覺失能之症狀，經多項檢查後排除鼻道阻塞及嗅神經病變之可能性，故診斷爲顏面創傷後之嗅覺失能。患者於創傷後七個月開始恢復嗅覺，目前仍於本院持續追蹤中。本病例提供臨床診治顱顏外傷或單純顏面外傷時，需注意發生創傷後嗅覺失能之可能，並提出簡單之測試流程與治療步驟。

Olfactory dysfunction is relatively common caused by head trauma, with a reported incidence between 4 and 7%. It is difficult to self recovery of the olfactory dysfunction caused by craniofacial trauma, and no standard treatment for post-traumatic olfactory dysfunction was reported. This case presents a young adult who had a facial trauma and recovery without any aggressive treatment. The patient was bumped by the car without loss of consciousness, and then received open reduction and internal fixation due to complicated fractures of maxillofacial area. After the condition of facial trauma became stable, he started to complain about lost of smell, and the bilateral post-traumatic anosmia was diagnosed. The neuropathy of olfactory nerve was ruled out after a series examinations. Fortunately, progressive recovery of the olfaction without any aggressive treatment was noted by seven months closely follow up. This report provided not only early awareness of olfactory dysfunction of patients had facial trauma but also introduced a simple method for diagnosis and management.
