Abstract
OBJECTIVE: To assess the safety and efficiency of cochlear implantation using a novel device with a linear silastic pedestal (2 mm wide, 2 mm deep, 10 mm long) on the flat undersurface.
METHODS: Operative times required to drill a linear groove (LG) for the new linear pedestal design were prospectively accrued for 46 implantations in 30 children (median age 3). Intra-operative safety was assessed during each case. Instances of dural exposure in the base of the LG were noted. Length of stay was also recorded as a secondary measure of efficiency.
RESULTS: Across all surgeons, the mean time needed to create the LG was 1.9 ± 1.5 min (±SD) with a median time of 1.5 min (95% Cl: 1-2 min). The range in time was 1-10 min. No intraoperative complications occurred. Intended device positioning was confirmed with on-table post-operative x-rays in all cases. 43% of patients were discharged on the day of surgery.
CONCLUSIONS: The novel linear pedestal design allows for deliberate device placement while adding little additional operative time and complexity, an improvement on our current standard of care.
