Consideration for routine outpatient pediatric cochlear implantation: A retrospective chart review of immediate post-operative complications.

Introduction: Cochlear implantation is well accepted as the treatment of choice for prelingual deafness in children [1]. However, the safety of routinely performing this procedure on an outpatient basis is debated. We aim to assess immediate postoperative complications that would affect a surgeon's decision to perform pediatric cochlear implantation on an outpatient basis.

Methods: A retrospective chart review was conducted which included all children 17 years old or younger who underwent cochlear implantation from 2004 to 2014 in a private neurotology practice. The immediate postoperative complication rates and types of complications were then examined.

Results: A total of 579 cochlear implants were placed in children ages 1-17 years old from 2004 to 2014. The most common complications were nausea/vomiting and dizziness/imbalance. The odds ratio of developing complications in the group ages 1-3 years old versus all other age patients was found to be statistically insignificant (OR 0.90, 95% CI 0.61 to 1.32, p = 0.58). The odds ratio of developing a complication after bilateral implantation compared to unilateral implantation was statistically significant (OR 1.96, 95% CI 1.18 to 3.28, p = 0.01). There was no difference in complication rates when comparing lateral wall and perimodiolar insertions. A total of 6 of 579 (1%) cochlear implants resulted in a complication requiring unplanned medical attention.

Conclusions: Overall, this series offers a decade of experience in pediatric cochlear implantation that shows a low incidence of the need for unplanned medical attention in the immediate postoperative period. The most common complication seen is Post-operative nausea and vomiting (PONV) that appears to be amenable to outpatient management even in the youngest populations. This supports providers routinely performing pediatric cochlear implantation on an outpatient basis.
