Enlarged vestibular aqueduct (EVA) is the most frequently identified anatomical abnormality in children with sensorineural hearing loss (Lin et al., 2005). The age at onset of hearing loss may range from birth to adolescence (Berrettini et al., 2005), but typically fluctuates or progresses to a profound degree by early childhood (Valvassori & Clemis, 1978). Many patients with EVA eventually will be referred for consideration for cochlear implantation (CI). Research has shown that this route can prove successful for these patients (Lai et al., 2012) if no other developmental delays are present. One previous study found that the average length of time between hearing sensitivity documented at a severe/profound hearing level and implantation was 6.3 months (Lee et al., 2010) during which period children would have limited access to language.
Studying a sample of 42 children who received CIs with a diagnosis of EVA, we investigated their status on newborn hearing screening, their progression of hearing sensitivity from identification of sensorineural hearing loss of any degree to severe/profound degree (candidacy criteria for CI), and the length of time between identification of severe/profound degree of hearing loss and surgical cochlear implantation.
Prior to progression in degree of hearing loss and subsequent surgical implantation, subjects of this current study were largely functionally hard of hearing and predominantly aural/oral communicators. Some children used signing in support of spoken English. When spoken language became no longer accessible auditorily, efforts to limit the amount of time between these children reaching audiological candidacy criteria and implantation was imperative to maintain access to spoken language.
Efforts to limit the amount of time between reaching audiological candidacy criteria and scheduling surgery may benefit patients. These findings contribute to influencing the anticipatory process of guidance for children and families by providing comprehensive management, supports, and recommendations for follow-along care.
- Describe the status of newborn hearing screening referral in this population.
- Describe the length of time between hearing deteriorating to CI candidacy and implantation.
