Abstract

Objective: To determine the prevalence, characteristics, and outcomes of pediatric patients with recurrent swelling over their cochlear implant receiver package.

Study design: Retrospective case review.

Setting: Tertiary referral center.

Patients: A total of 332 bilateral cochlear implant patients under the age of 18 years were reviewed. Twelve patients with more than one episode of swelling around their cochlear implant receiver package were isolated. Patients with clinical evidence of infection were excluded from the study. The etiology of hearing loss was heterogeneous.

Intervention: Three patients underwent ultrasound, and three patients underwent bedside aspiration. Most patients were treated with 7 days of oral broad-spectrum antibiotics.

Main outcome measure: Incidence, frequency, and course of recurrent swelling around cochlear implant receiver packages.

Results: The first swelling appeared between 0.86 and 9.95 years after surgery (mean, 3.38), and the occurrence of the last episode ranged from 0.06 to 3.42 years from the current date (mean, 1.04). The total number of episodes ranged from 2 to 18 (mean, 6). Seven patients had unilateral swellings, and five had bilateral swellings. Swellings were associated with upper respiratory tract infection or minor trauma, or had no identifiable cause. Aspiration in three cases showed evidence of altered blood.

Conclusions: Recurrent otherwise asymptomatic swelling over cochlear implant receiver packages in children is more common than initially thought. Possible causes include hematoma and seroma secondary to upper respiratory tract infection. The incidence and the timing of swelling are variable. There were no swelling-related device failures or reimplantations so patients and parents can be reassured about the long-term outcome.
