Novel Surgical Technique in Active Bone Conduction: Minimally Invasive Approach to Fully Implantable Osseointegrated...

We report our experience using a novel minimally invasive surgical technique for implantation of a fully implantable active bone conduction implant. This was a retrospective review of 16 adults, including 10 women and 6 men. The mean age was 54 years. Hearing loss profiles included 8 with mixed hearing loss, 5 with conductive hearing loss, and 3 with single-sided deafness. Nine patients underwent placement through the standard approach and 7 with the minimally invasive approach. There were no postoperative complications at a mean follow-up of 6.5 months (SD, 4; range, 1.5-12), and all patients received audiologic benefit with objective improvement in sound-field thresholds upon activation. Mean operative time was shorter with the minimally invasive approach (64 vs 41 minutes, P = .01). The fully implantable bone-anchored auditory implant can be effectively placed via a minimally invasive incision, with potential benefits of decreased operative time, low risk for intra- and postoperative complications, and rapid healing.
