This study amied to elucidate the case of an older patient suffering from aural myiasis caused by . An 81-year-old female patient with a history of middle ear surgery and dementia presented with bleeding in her right ear and visible worms. Upon initial examination, a larva was found crawling on the right auricle. Further examination revealed numerous larvae, purulent otorrhea, and active bleeding in the external auditory canal and mastoid cavity. All larvae were successfully removed with ear irrigation. The patient was diagnosed with otitis media and treated with antibiotic ear drops, resulting in significant clinical improvement. The larvae were later identified morphologically as , a species of Calliphoridae. This case highlights the potential for aural myiasis in elderly patients with dementia and otitis media, who may be at increased risk for the condition.
本研究旨在阐明一例老年患者患耳蛆病的病例。一名81岁女性患者,有中耳手术史和痴呆症,出现右耳出血且可见蠕虫。初诊时,发现一只幼虫在右耳廓爬行。进一步检查发现外耳道和乳突腔内有大量幼虫、脓性耳漏和活动性出血。通过耳冲洗成功清除了所有幼虫。患者被诊断为中耳炎,并用抗生素耳滴剂治疗,临床症状显著改善。这些幼虫后来经形态学鉴定为丽蝇科的一种。该病例突出了患有痴呆症和中耳炎的老年患者发生耳蛆病的可能性,这类患者可能患此病的风险增加。
