A previous study found sensorineural hearing loss in 13% of 178 children with solitary preauricular tags. The present results are quite different. Audiological assessment was performed on 42 children (median age of 2 months) with preauricular tags as the sole anatomical malformation. Tests included behavioral audiometry and transient evoked otoacoustic emissions. Twenty-two subjects were also tested with auditory brainstem recording while under general anesthesia during surgical excision of the tag. None of the children had a sensorineural hearing loss, but 4 had a bilateral or unilateral conductive hearing loss due to secretory otitis media. It is concluded that solitary ear tags are not a high risk factor for sensorineural hearing loss if not associated with a family history of hearing loss.
一项先前的研究发现,在178例患有孤立性耳前瘘管的儿童中,13%存在感音神经性听力损失。目前的结果则大不相同。对42例(中位年龄2个月)以耳前瘘管作为唯一解剖畸形的儿童进行了听力学评估。测试包括行为测听和瞬态诱发耳声发射。22名受试者在瘘管手术切除的全身麻醉期间还接受了听性脑干反应测试。这些儿童均无感音神经性听力损失,但有4例因分泌性中耳炎出现双侧或单侧传导性听力损失。得出的结论是,如果不伴有听力损失家族史,孤立性耳前瘘管并非感音神经性听力损失的高危因素。
