擴張入顳骨乳突的嚴重閉塞性角化症

Severe Keratosis Obturans with Expansion into the Mastoid Process of the Temporal Bone

Abstracts


耳垢栓塞在一般門診相當地常見,可能原因爲外耳道形狀異常或耳道口受到阻塞。一38歲女性,因嚴重的左側外耳道耳垢栓塞導致耳痛及聽障1個月,自基層診所轉診於本院,經過1個月的局部用藥與5次的局部處置後才把耳垢完全取出。最後,發現已經擴大變形的外耳道,電腦斷層顯示外耳道已擴大入顳骨乳突。根據臨床特徵,本個案診斷爲嚴重的閉塞性角化症,由於罕見,特提出報告。

Cerumen impaction is quite common, and may be caused by deformity or by obstruction of the external auditory canal (EAC). A 38-year-old female presented with left earache and hearing block that had lasted a month. Severe cerumen impaction of the EAC was identified at a private clinic. Over the next month, five local treatment sessions were performed at our hospital, and the cerumen was gradually removed; finally, an expanded EAC was identified. Computed tomography revealed that the EAC had expanded into the mastoid process. Finally, keratosis obturan was diagnosed. This is rare and a curiosity, therefore we are reporting the case here.
