RESULTS

The type and etiology of the hearing impairments being rehabilitated with the OSIA2 were heterogeneous but representative of the pediatric population that may seek surgical bone conduction hearing habilitation. Twelve of the 42 children had secondary diagnoses, including four children with Trisomy 21, two with chromosome 18Q deletion, and one child each with Goldenhar, Treacher Collins, Branchio-Oto-Renal, Waardenburg 2E Syndrome, Trisomy 8 and 22, and multiple congenital anomalies.

Mean surgical time was 69 minutes. Soft tissue reduction was required in one child who was obese. There were no subsequent postoperative issues with magnet fitting in this patient. One patient required bone polishing to achieve clearance for placement of the actuator. Surgical complication occurred in two children who experienced irritation at the magnet and incision site due to frequent usage. The soft tissue irritation and mild skin breakdown resolved upon the addition of a magnet soft pad to the external processor.
