摘要

外耳道鈕扣電池異物併發耳膜穿孔實為少見。1名8歲的兒童患者因不慎將鈕扣電池置入外耳道，持續性耳痛3天。採局部外耳道浸潤麻醉後，順利取出電池。檢耳鏡發現除外耳道顯示紅腫外，另可見耳膜具穿孔併鼓膜炎。予以生理食鹽水擦拭外耳道並塗抹抗生素軟膏局部治療，開立口服抗生素與及止痛劑治療，並衛教病患保持外耳道乾燥。耳膜穿孔於1周後追蹤時已癒合，且追蹤聽力亦無異常表現。該患者在後續追蹤恢復良好並無其餘併發症。

Button battery as an external auditory meatus foreign body complicated with tympanic membrane perforation is rare. One 8-year-old child was referred from emergency room with severe otalgia and a button battery foreign body in the right ear for 3 days. Under topical anesthesia with 4% xylocaine spray, an alkaline button battery (LR41) was removed. Congestion of the ear canal and a small perforation on upper right tympanic membrane with diffuse peripheral myringitis were observed. Topical neomycin ointment and oral antibiotics and analgesics were administered. Tympanic membrane perforation healed one week later, and pure tone audiogram reported normal hearing level. The patient remains symptom free after six-month follow-up.
