Abstract
Objective: Assess stability of a new design titanium implant (Cochlear Baha BI300) in bone anchored hearing aid (Baha) recipients over time in a prospective, nonrandomized, one-group study at a tertiary care institution.
Method: Twelve patients who underwent one-stage Baha surgery over 4 months have been analyzed. Implant stability was measured with Implant Stability Quotient (ISQ) measurement tests. Patients were tested at surgery and every week after, for 1 year. Two-tailed Student test was calculated for all comparisons. P < .05 was considered significant.
Results: The new implant showed a steep increase of ISQ values over the first 2 weeks and reached stable ISQ values 3 weeks after surgery. No significant difference on ISQ values was evident between children and adults. Complete healing time was obtained in 8 days on average (range, 7-12 days; median, 7.6). Neither implant extrusion nor skin revision surgery was observed in our patients during the first year of follow-up.
Conclusion: In our hands this new implant revealed stability and fast integration. The data from the present study suggest the new implant may be suitable for early loading protocols.
