Nasal leech infestation rarely occurs in society today and it is usually reported as an anecdote. In this study, we present seven nasal leeches in six patients from 1984 to 2008. All patients initially presented with epistaxis. Four patients were less than 8 years old and two patients were older than 60 years old. All patients had spent time in rural streams 2 weeks to 2 months before the symptoms occurred. All of the seven leeches were removed smoothly and one leech migrated to the oropharynx during the operation. The length of the leeches ranged from 2 to 12 cm with an average length of 4.6 cm. Attention should be given to nasal leech infestation, especially in children and senior citizens who have visited rural streams and have been exposed to freshwater. One of our patients had two leeches lodged in his nasal cavities. Therefore, it is also important to re-examine both nasal cavities after the removal of one leech.
鼻腔水蛭感染在当今社会很少见，通常被当作奇闻轶事报道。本研究报告了 1984 年至 2008 年间 6 例患者的 7 例鼻腔水蛭感染。所有患者最初均表现为鼻出血。4 例患者年龄小于 8 岁，2 例患者年龄大于 60 岁。所有患者在出现症状前均有 2 周至 2 个月的时间在农村溪流中度过。7 只水蛭均顺利取出，1 只水蛭在手术过程中迁移至口咽部。水蛭的长度从 2 至 12 cm 不等，平均长度为 4.6 cm。应注意鼻腔水蛭感染，尤其是曾去过农村溪流、接触过淡水的儿童和老年人。我们的 1 例患者鼻腔内有 2 只水蛭。因此，在取出 1 只水蛭后，对双侧鼻腔进行再次检查也很重要。
