A 28-year-old female domestic helper presented to the Ear, Nose, and Throat clinic complaining of three weeks of right otalgia associated with a right blocked ear. The hearing was otherwise normal, and she denied otorrhoea, dizziness or imbalance, ear digging, or water contact, and has no history of ear eczema. She has no other past medical history and no recent travel history. On examination, numerous whitish ovoid lesions were seen lining the entire right external auditory canal (EAC), admixed with debris, and the canal was inflamed. Her tympanic membrane was intact. The contralateral ear was normal. She was diagnosed with otoacariasis. The ear mites were unable to be retrieved for a direct microscopic examination, but based on the ovoid, smooth, and translucent morphology of the mites, they likely belong to the Acaridae or Chortoglyphidae families of mites. She underwent aural toileting for complete removal of the ear mites and was prescribed ear drops containing dexamethasone and polymyxin B sulfate for 2 weeks. She was reviewed using the otomicroscopy technique two weeks later and had made an uneventful recovery with no recurrence of ear mites.
一名28岁的女性家政工到耳鼻喉科诊所就诊，主诉右耳疼痛三周，伴有右耳堵塞感。听力其他方面正常，她否认有耳漏、头晕或失衡、挖耳或接触水的情况，也没有耳部湿疹病史。她没有其他既往病史，近期也没有旅行史。检查时，可见整个右外耳道内有许多白色卵圆形病变，混有碎屑，外耳道发炎。她的鼓膜完整。对侧耳朵正常。她被诊断为耳螨病。耳螨无法取出进行直接显微镜检查，但根据螨的卵圆形、光滑和半透明形态，它们可能属于螨科或嗜卷叶螨科。她接受了耳道清理以彻底清除耳螨，并被开了含有地塞米松和硫酸多粘菌素B的耳滴剂，为期两周。两周后使用耳显微镜技术对她进行复查，她恢复顺利，耳螨没有复发。
