Audiological assessment of infants and children with preauricular tags.
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.
