Three hundred and ten patients were examined by otoscopy. Age, sex, social class and use of cotton buds for aural toilet were recorded. The incidence of visually occlusive wax plugs in the external auditory canals was not significantly different between users and non-users of cotton buds, either in children or in adults.
310名患者接受了耳镜检查。记录了患者的年龄、性别、社会阶层以及是否使用棉签进行耳部清洁。无论儿童还是成人，使用棉签和不使用棉签的人群中，外耳道可见性堵塞性耵聍栓塞的发生率并无显著差异。
